How to Choose Your Ideal Lens - Healthy Blue Zone

Choosing the ideal lens isn’t just about clear vision; it’s a profound investment in your long-term health and quality of life. For many, glasses or contact lenses are a daily necessity, but the right lens can do so much more than correct a prescription. It can protect your eyes from harmful light, reduce strain, enhance visual comfort in various environments, and even impact your overall well-being. This comprehensive guide will equip you with the knowledge to make an informed decision, moving beyond basic vision correction to consider the holistic health benefits of your lens choice.

Understanding Your Eyes: Beyond the Prescription

Before diving into specific lens types, it’s crucial to understand the intricate world of your own eyes and how they interact with your environment. Your ophthalmologist or optometrist provides a prescription that addresses refractive errors like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. However, your eyes are also constantly exposed to a spectrum of light, from natural sunlight to artificial sources, and subjected to varying visual demands throughout your day.

Refractive Errors and Their Impact:

Myopia (Nearsightedness): Distant objects appear blurry because light focuses in front of the retina. This often leads to squinting, headaches, and eye strain when trying to see things far away.
Hyperopia (Farsightedness): Near objects appear blurry because light focuses behind the retina. This can cause discomfort, fatigue, and difficulty with reading or close-up tasks.
Astigmatism: Irregular curvature of the cornea or lens causes blurred or distorted vision at all distances. Symptoms include eye strain, headaches, and difficulty with night driving.
Presbyopia: The natural age-related loss of the eye’s ability to focus on close objects, typically starting in the early to mid-40s. This requires reading glasses, bifocals, or progressive lenses.

Beyond Refractive Errors: Environmental and Lifestyle Factors:

Your daily activities, work environment, and even the climate you live in significantly influence the demands placed on your eyes. Consider:

Digital Device Usage: Prolonged exposure to screens (computers, smartphones, tablets) can lead to digital eye strain (DES), characterized by dry eyes, blurred vision, headaches, and neck pain.
Outdoor Exposure: UV radiation from the sun is a major contributor to cataracts, macular degeneration, and other eye conditions. Glare can also cause discomfort and reduce visual clarity.
Occupational Hazards: Certain professions, like welding, construction, or laboratory work, expose eyes to intense light, flying debris, or chemicals, necessitating specialized protective eyewear.
Driving: Night driving presents challenges with glare from headlights and reduced visibility, while daytime driving requires optimal clarity and protection from sun glare.
Hobbies and Sports: Activities like reading, crafting, cycling, or swimming have unique visual requirements and potential risks that should inform your lens choice.

The Foundation of Health: Essential Lens Features

Every lens you choose should ideally incorporate certain fundamental features that promote ocular health and general well-being, regardless of your specific prescription. These are non-negotiables for a truly health-focused lens.

UV Protection: Your Eyes’ Sunscreen

Just as you protect your skin from the sun, your eyes require robust UV protection. Ultraviolet (UV) radiation, both UVA and UVB, is a silent threat that can damage the delicate structures of your eyes over time, even on cloudy days.

Why it’s crucial for health:

Cataract Prevention: Prolonged UV exposure is a significant risk factor for cataracts, a clouding of the eye’s natural lens that impairs vision and often requires surgery.
Macular Degeneration Risk Reduction: While not the sole cause, UV light is believed to contribute to age-related macular degeneration (AMD), a leading cause of severe vision loss in older adults.
Pterygium and Pinguecula Prevention: These growths on the white of the eye are often linked to chronic UV exposure and can cause irritation and, in severe cases, obstruct vision.
Photokeratitis (Sunburn of the Eye): Acute exposure to high levels of UV, such as from reflected snow or water, can cause a painful “sunburn” of the cornea.

What to look for:

Insist on lenses that block 100% of UVA and UVB rays up to 400 nanometers (UV400). This is a non-negotiable feature for all lenses, including clear prescription lenses, sunglasses, and even some contact lenses. Don’t assume all lenses offer this; specifically ask your optician.

Concrete Example: Imagine an avid gardener who spends hours outdoors. Without 100% UV protection, their eyes are constantly bombarded by harmful rays, increasing their risk of cataracts and other conditions. A pair of everyday clear glasses with UV400 protection acts as a continuous shield, even when they’re not actively thinking about sun exposure.

Anti-Reflective (AR) Coating: The Glare Eliminator

An anti-reflective coating, also known as anti-glare coating, is a microscopic layer applied to the lens surface that eliminates reflections from the front and back surfaces of your lenses. While often considered a comfort feature, its health benefits are substantial.

Why it’s crucial for health:

Reduced Eye Strain and Fatigue: Reflections on your lenses can cause constant visual distractions, forcing your eyes to work harder to focus, leading to fatigue, headaches, and blurry vision. AR coating provides clearer, crisper vision by allowing more light to pass through the lens.
Enhanced Night Vision and Driving Safety: Glare from oncoming headlights, streetlights, and reflections off the road can be significantly reduced, improving clarity and reaction time while driving at night.
Improved Digital Eye Strain Symptoms: When working on computers, reflections from overhead lights or windows can bounce off your screen and then off your glasses, contributing to digital eye strain. AR coating minimizes this.
Better Cosmetic Appearance: While not a direct health benefit, clear lenses without distracting reflections can reduce self-consciousness, contributing to overall mental well-being.

What to look for:

High-quality AR coatings are multi-layered and durable, often incorporating scratch resistance, smudge resistance, and hydrophobic (water-repellent) properties. Don’t settle for basic AR; ask about premium options that offer superior clarity and longevity.

Concrete Example: Consider a student who spends hours studying and working on a laptop. Without an AR coating, the glare from the desk lamp reflecting off their lenses would constantly interfere with their focus, leading to tired, burning eyes by the end of the day. With AR coating, their eyes experience less strain, allowing for more productive and comfortable study sessions.

Scratch Resistance: Durability for Ongoing Protection

While not directly a health feature in the same vein as UV or AR, a durable, scratch-resistant coating contributes indirectly to eye health by preserving the integrity and performance of your lenses.

Why it’s crucial for health:

Maintained Optical Clarity: Scratches on your lenses distort light, leading to blurry vision, increased glare, and a constant need for your eyes to compensate, causing strain and fatigue.
Extended Lens Lifespan: Durable lenses mean less frequent replacement, ensuring continuous access to clear, protective vision.
Cost-Effectiveness and Convenience: While an initial investment, scratch-resistant coatings save money and hassle in the long run by reducing the need for premature lens replacement.

What to look for:

Most modern lenses come with a basic scratch-resistant coating. However, premium versions offer superior durability. Ask about specific brand-name coatings known for their toughness.

Concrete Example: An active individual who frequently puts their glasses down on various surfaces or carries them in a bag without a case will quickly accumulate scratches on unprotected lenses. These scratches turn clear vision into a hazy, distorted experience, forcing their eyes to constantly adapt and leading to headaches. A robust scratch-resistant coating preserves the optical quality, ensuring consistent clear vision and preventing unnecessary eye strain.

Specialized Lens Technologies for Optimal Eye Health

Beyond the foundational features, a variety of advanced lens technologies cater to specific health concerns and lifestyle demands, offering tailored protection and comfort.

Blue Light Filtering Lenses: Mitigating Digital Strain

Blue light, a segment of the visible light spectrum with short, high-energy wavelengths, is emitted in significant quantities by digital screens (smartphones, tablets, computers, LED lighting). While blue light is naturally present in sunlight and has benefits (like regulating sleep cycles), excessive exposure, especially at night, is a growing concern.

Why it’s crucial for health:

Reduced Digital Eye Strain (DES): Blue light contributes to glare and can cause visual discomfort, blurred vision, dry eyes, and headaches associated with prolonged screen use. Filtering it can alleviate these symptoms.
Improved Sleep Quality: Exposure to blue light, particularly in the evening, can suppress melatonin production, disrupting your natural sleep-wake cycle (circadian rhythm). Filtering it can help maintain healthier sleep patterns.
Potential Retinal Protection: While research is ongoing and not conclusive, some studies suggest that long-term, high-intensity exposure to certain blue light wavelengths might contribute to retinal damage over time. Filtering it is a precautionary measure.

What to look for:

Blue light filtering can be incorporated into lenses in two primary ways:

Lens Material (In-Mass Filtration): The blue light filter is embedded directly into the lens material during manufacturing, providing more comprehensive and less visible filtration.
Coating (Surface Filtration): A blue light filtering coating is applied to the lens surface, often giving a slight blue reflection. These can be effective but sometimes less comprehensive than in-mass filtration.

Discuss your daily screen time and sleep concerns with your eye care professional to determine the most appropriate level of blue light filtration for you.

Concrete Example: A graphic designer who spends 10+ hours a day in front of multiple high-resolution monitors is an ideal candidate for blue light filtering lenses. Without them, they might experience constant eye fatigue, difficulty focusing, and disrupted sleep due to evening screen exposure. With blue light lenses, they can work more comfortably, experience less strain, and maintain healthier sleep patterns, directly impacting their overall productivity and well-being.

Photochromic Lenses (Transitions®): Dynamic UV and Glare Protection

Photochromic lenses, often known by the brand name Transitions®, are lenses that automatically darken when exposed to UV light outdoors and return to clear indoors. They offer a convenient two-in-one solution for vision correction and sun protection.

Why it’s crucial for health:

Continuous UV Protection: They provide 100% UV protection both when clear and when darkened, ensuring your eyes are constantly shielded from harmful rays without needing to switch between glasses.
Reduced Glare and Eye Strain Outdoors: By adapting to varying light conditions, they reduce squinting and discomfort in bright environments, minimizing eye fatigue.
Convenience for Active Lifestyles: Ideal for individuals who frequently move between indoor and outdoor environments, eliminating the need to carry separate prescription sunglasses. This ensures consistent eye protection.
Protection from Harmful Blue Light (Advanced Versions): Newer generations of photochromic lenses often incorporate blue light filtering technology, providing comprehensive protection indoors and out.

What to look for:

Activation Speed and Fade-Back Time: How quickly do they darken and clear? Newer generations are much faster.
Darkness Level: Do they get dark enough for your outdoor activities? Some photochromics are designed for specific outdoor use, like driving (blocking UV through the car windshield).
Indoor Clarity: Do they return to a completely clear state indoors? High-quality versions are virtually clear.
Temperature Sensitivity: Some older photochromic lenses are less effective in very hot temperatures.

Concrete Example: An architect who frequently moves from an indoor office environment to outdoor construction sites would greatly benefit from photochromic lenses. Instead of constantly switching between their prescription glasses and prescription sunglasses, their photochromic lenses adapt seamlessly, ensuring continuous UV protection and comfortable vision as they navigate different lighting conditions throughout their workday. This reduces inconvenience and ensures consistent eye health protection.

Polarized Lenses: Superior Glare Reduction (Especially for Reflections)

Polarized lenses are specifically designed to reduce glare from reflective surfaces like water, snow, roads, and car hoods. They achieve this by containing a special filter that blocks horizontally polarized light, which is the light that causes glare.

Why it’s crucial for health:

Enhanced Visual Comfort and Reduced Eye Strain: By eliminating harsh glare, polarized lenses provide significantly more comfortable vision, reducing the need to squint and alleviating eye fatigue, especially during outdoor activities.
Improved Clarity and Contrast: They enhance color perception and visual clarity, making it easier to see objects in bright, reflective environments.
Increased Safety for Driving and Outdoor Sports: Glare from wet roads or reflections can be dangerous while driving. For activities like fishing or boating, polarized lenses allow you to see below the surface of the water, improving safety and performance.
Protection from Disabling Glare: Certain types of glare can be so intense that they temporarily blind you. Polarized lenses effectively mitigate this risk.

What to look for:

While often found in sunglasses, polarized lenses can be prescription. Ensure they are true polarized lenses, not just tinted. Test them by looking at a reflective surface (like a car windshield) and rotating the lenses; if they are polarized, the glare will significantly diminish.

Concrete Example: A keen angler who spends weekends fishing on a lake would find polarized lenses indispensable. Unpolarized sunglasses would only darken the view, but the glare reflecting off the water’s surface would still obscure their vision, making it hard to spot fish or navigate. Polarized lenses cut through this glare, allowing them to see clearly beneath the surface, reducing eye strain from constant squinting and enhancing their overall enjoyment and success.

Lens Materials: Impacting Comfort, Durability, and Safety

The material from which your lenses are made plays a significant role in their weight, thickness, optical clarity, durability, and impact resistance – all factors that affect your comfort and eye safety.

CR-39 Plastic: The Traditional Standard

CR-39 plastic has been the standard lens material for decades. It’s inexpensive and offers good optical clarity.

Health and Safety Considerations:

Good Optical Clarity: Provides clear vision.
Lower Impact Resistance: Compared to newer materials, CR-39 is more prone to shattering upon impact, posing a safety risk for active individuals or children.
Thicker and Heavier: For higher prescriptions, CR-39 lenses can be noticeably thick and heavy, which can be uncomfortable and affect frame choice.

Concrete Example: For someone with a very low prescription and a sedentary lifestyle who primarily wears glasses indoors, CR-39 might be an acceptable, cost-effective choice. However, for a child playing sports, the lack of impact resistance would be a serious safety concern.

Polycarbonate: The Safety Standard

Polycarbonate is a thinner, lighter, and significantly more impact-resistant material than CR-39, making it an excellent choice for safety and active lifestyles.

Why it’s crucial for health and safety:

Exceptional Impact Resistance: Polycarbonate is 10 times more impact-resistant than CR-39, providing superior protection against blunt force trauma, making it ideal for children, athletes, and those in hazardous work environments.
Thinner and Lighter: For the same prescription, polycarbonate lenses are considerably thinner and lighter than CR-39, offering greater comfort and a more aesthetically pleasing appearance, especially for higher prescriptions.
Built-in UV Protection: Polycarbonate naturally blocks 100% of UV rays, providing inherent sun protection.

What to look for:

For children, sports eyewear, or safety glasses, always specify polycarbonate lenses. Many eye care professionals automatically recommend it for these applications.

Concrete Example: A construction worker needs lenses that can withstand potential impacts from flying debris. Polycarbonate lenses are mandatory for their safety eyewear, as they offer vastly superior impact resistance compared to standard plastic, preventing serious eye injuries. Similarly, a child playing soccer benefits immensely from polycarbonate lenses, protecting their eyes during accidental bumps or falls.

Trivex: Superior Optics with High Impact Resistance

Trivex is a relatively newer lens material that combines the best qualities of CR-39 and polycarbonate: excellent optical clarity and high impact resistance.

Why it’s crucial for health and safety:

Superior Optical Clarity: Trivex offers higher optical clarity (less chromatic aberration, or color fringing) than polycarbonate, making it preferred by some for professions requiring very precise vision.
High Impact Resistance: While slightly less impact-resistant than polycarbonate, it’s still significantly more robust than CR-39 and meets safety standards for protective eyewear.
Thinner and Lighter than CR-39: Similar to polycarbonate, it offers a thinner and lighter profile for higher prescriptions.
Built-in UV Protection: Trivex also naturally blocks 100% of UV rays.

What to look for:

Trivex is often recommended for individuals who desire the highest optical quality combined with excellent impact resistance, or for those with specific visual demands where subtle optical distortions are critical.

Concrete Example: A surgeon performing delicate procedures might choose Trivex lenses. While polycarbonate offers impact resistance, Trivex provides a slightly clearer, distortion-free view crucial for precise work, while still offering the necessary protection against accidental impacts within a clinical setting.

High-Index Lenses: Thinness for Higher Prescriptions

High-index lenses are made from materials that bend light more efficiently, allowing them to be much thinner and lighter than standard materials for the same prescription power.

Why it’s crucial for health and aesthetics:

Reduced Weight and Thickness: For individuals with strong prescriptions, high-index lenses dramatically reduce the weight and “coke bottle” appearance, leading to greater comfort, less pressure on the nose and ears, and a more aesthetically pleasing result.
Improved Peripheral Vision: Thicker lenses can distort peripheral vision. High-index lenses minimize this, providing a wider, clearer field of view.
Wider Frame Choice: Lighter, thinner lenses open up a broader range of frame styles that might otherwise be unsuitable due to lens thickness.
Reduced Eye Strain (Indirectly): While not directly a health benefit, the increased comfort and improved aesthetics can reduce self-consciousness and discomfort, contributing to overall well-being.

What to look for:

High-index lenses are available in various indices (e.g., 1.67, 1.74), with higher numbers indicating thinner lenses. Your eye care professional will recommend the appropriate index based on your prescription. Always combine high-index lenses with a good anti-reflective coating, as their surfaces are more prone to reflections.

Concrete Example: Someone with a very strong prescription of -8.00 might find traditional CR-39 lenses incredibly thick, heavy, and visually distorting. Switching to a 1.74 high-index lens would result in lenses that are dramatically thinner and lighter, making their glasses far more comfortable to wear throughout the day and reducing the visual bulk that might cause self-consciousness.

Specific Lens Designs for Lifestyle and Health Needs

Beyond materials and coatings, the design of the lens itself is paramount, especially for addressing presbyopia and optimizing vision for specific activities.

Single Vision Lenses: Basic Correction

Single vision lenses have one power throughout the entire lens and are used to correct myopia, hyperopia, or astigmatism for a single viewing distance (e.g., distance vision, reading vision).

Health Considerations:

Simple and Effective: For those without presbyopia, they offer straightforward correction.
Potential for Eye Strain (if not combined with other features): If used for prolonged computer work without blue light filtering or AR coating, or for outdoor activities without UV protection, they can still lead to eye strain and long-term damage.

Concrete Example: A young adult with only nearsightedness would use single vision lenses for clear distance vision. If they spend significant time on a computer, adding a blue light filter to these lenses would protect their eyes from digital strain.

Bifocal Lenses: Two Vision Zones

Bifocal lenses have two distinct power zones: a larger top portion for distance vision and a smaller segment at the bottom for near vision. A visible line separates these two zones.

Health Considerations:

Clear Distinction: Provides clear vision for distance and near, reducing the need to constantly put on and take off reading glasses.
Image Jump: The abrupt change in power at the line can cause “image jump,” where objects appear to shift as your eyes move between zones. This can be disorienting and potentially lead to falls in some individuals, especially older adults navigating stairs.
Limited Intermediate Vision: Bifocals don’t offer a specific zone for intermediate distances (like a computer screen), which can still lead to strain for tasks at arm’s length.

Concrete Example: An individual in their 60s who enjoys reading books and driving would find bifocals functional. They can look through the top for the road and easily drop their gaze to the bottom segment for reading maps or their car’s dashboard. However, they might still struggle with the clarity of a computer screen at arm’s length.

Progressive Lenses (No-Line Bifocals): Seamless Transitions

Progressive lenses, also known as no-line bifocals or varifocals, provide a seamless progression of power from distance vision at the top, through an intermediate zone in the middle, to near vision at the bottom. There is no visible line.

Why it’s crucial for health and comfort:

Natural Vision: Mimics natural vision more closely than bifocals, allowing the eyes to adjust smoothly between different distances without image jump. This reduces visual fatigue and improves comfort.
Comprehensive Vision: Offers clear vision at all distances – distance, intermediate (computer, dashboard), and near (reading). This is invaluable for modern lifestyles.
Improved Balance and Safety: Without the image jump of bifocals, progressive lenses can improve balance and reduce the risk of falls, especially on stairs or uneven surfaces.
Aesthetics: The absence of a visible line is often preferred cosmetically.

What to look for:

Design Quality: Not all progressive lenses are created equal. Premium progressive designs offer wider fields of view and less peripheral distortion (“swim”) than basic designs.
Adaptation Period: There’s typically an adaptation period as your brain learns to use the different zones. High-quality designs often have shorter, easier adaptation periods.
Consultation with Optician: A skilled optician is essential for precise measurements and fitting to ensure the optimal performance of your progressive lenses.

Concrete Example: A university professor who lectures (distance), works extensively on a computer (intermediate), and reads research papers (near) would find progressive lenses revolutionary. They can seamlessly transition between looking at their students, checking notes on their laptop, and reading a book, all without switching glasses or experiencing the jarring “image jump” of bifocals, reducing eye strain and improving workflow.

Computer Lenses (Intermediate & Near): Office Ergonomics

Computer lenses are specialized progressive lenses designed with a larger, wider intermediate zone and a generous near zone, specifically optimized for computer work and desk-related tasks. They typically do not have a distance vision component.

Why it’s crucial for health:

Targeted Digital Eye Strain Relief: Directly addresses the visual demands of computer use, providing optimal clarity at arm’s length and for reading, significantly reducing digital eye strain, neck pain, and headaches associated with awkward postures from leaning in or craning the neck.
Ergonomic Comfort: Allows for a more natural head and neck position while working on screens, promoting better posture and reducing musculoskeletal discomfort.
Enhanced Productivity: By providing comfortable, clear vision for the specific distances of an office environment, these lenses can improve focus and productivity.

What to look for:

Discuss your specific work setup (single vs. multiple monitors, distance to screen, reading material) with your eye care professional to determine if computer lenses are right for you and what type of design would be most beneficial.

Concrete Example: An accountant who spends 8 hours a day in front of a dual-monitor setup, constantly referencing spreadsheets and documents, would benefit immensely from computer lenses. Traditional progressive lenses might have too narrow an intermediate zone, forcing them to constantly move their head to find focus. Computer lenses provide a wide, comfortable field of view for their screens and paperwork, preventing strain and promoting a more ergonomic posture throughout their workday.

The Fit and Dispensing: The Unsung Heroes of Lens Performance

Even the most advanced lens technology is useless if it’s not properly fitted to your face and prescription. The role of your eye care professional and the precision of the dispensing process are critical for optimal vision, comfort, and health benefits.

Accurate Prescription and Measurements

Your eye exam provides the foundational prescription, but precise measurements are needed to translate that into your ideal lenses.

Pupillary Distance (PD): The distance between the centers of your pupils. Incorrect PD can lead to prismatic effects, causing eye strain, headaches, and even double vision.
Optical Center Height: The vertical placement of the optical center of the lens relative to your pupil. Misalignment can induce unwanted prism and strain.
Vertex Distance: The distance between the back surface of your lens and the front of your cornea. This is particularly important for higher prescriptions.
Pantoscopic Tilt: The angle at which your frames tilt relative to your face.
Face Wrap: The curve of the frame around your face.

Why it’s crucial for health:

These precise measurements ensure that the optical center of the lens aligns perfectly with your pupil, allowing light to enter your eye correctly. Even slight misalignments can introduce distortions, prismatic effects, and lead to significant eye strain, headaches, and reduced visual clarity, negating the benefits of even the best lenses.

Concrete Example: If a progressive lens is not measured and fit precisely, the distinct vision zones won’t align with the wearer’s natural eye movements. This means they’ll constantly be “hunting” for the clear spots, leading to frustration, dizziness, and ultimately, an inability to adapt to the lenses, rendering them ineffective and uncomfortable.

Frame Selection and Adjustment

The frame you choose directly impacts how well your lenses perform and how comfortable they are.

Lens Size and Shape: Larger lenses offer a wider field of view, especially important for progressive lenses. The shape should complement your face but also accommodate your prescription without making the lenses excessively thick or heavy.
Frame Fit: The frame should sit comfortably on your nose without slipping, and the temples should rest gently behind your ears. A poorly fitting frame will constantly slide, causing the optical centers to shift and resulting in blurry vision and discomfort.
Adjustability: Ensure the frame can be adjusted by your optician to achieve the perfect fit.

Why it’s crucial for health:

A well-fitting frame ensures the lenses stay in their optimal position relative to your eyes. A loose or ill-fitting frame causes constant shifting, leading to distorted vision, persistent eye strain as your eyes try to compensate, and discomfort from pressure points.

Concrete Example: Imagine someone with a high prescription choosing a very large, oversized frame for a fashion statement. Even with high-index lenses, the sheer size of the lens area might make the glasses uncomfortably heavy, causing nose indents and headaches. Furthermore, the optical centers might be difficult to align properly in such a large lens, leading to visual distortions. A skilled optician would guide them towards a more appropriately sized frame.

Conclusion: Your Vision, Your Health, Your Choice

Choosing your ideal lens is a multifaceted decision that extends far beyond simply correcting your prescription. It’s about empowering your eyes with the protection, comfort, and clarity they need to support your overall health and well-being throughout your life. From foundational UV protection and anti-reflective coatings to specialized blue light filters, photochromic transitions, and polarized glare reduction, each lens feature and material plays a vital role.

Understanding your specific lifestyle, daily activities, and potential environmental exposures is paramount. Are you a digital professional battling screen fatigue? An outdoor enthusiast seeking robust sun protection? A multi-tasking individual needing seamless vision at all distances? Your answers will guide you toward the right combination of technologies.

Ultimately, your eye care professional is your most valuable resource. Engage in an open, detailed discussion about your visual habits, concerns, and aspirations. They possess the expertise to translate your needs into the perfect lens solution, ensuring that your investment in eyewear is an investment in your long-term health and a clearer, more comfortable view of the world. Make an informed choice, and see the difference it makes.
