10 Reasons Why Prescription Sunglasses are Necessary for Eye Health
6 Min Read September 8th, 2023

Sunglasses are an essential accessory on bright, sunny days. They allow you to see more clearly and protect your eyes from harmful ultraviolet (UV) radiation. According to the American Optometric Association, a sunglass should block out 100% of both UV-A and UV-B radiation, screen out 75 to 90% of visible light, and have a lens that should be free of distortions or imperfections in sight and clear color recognition. 

If you require corrective lenses, prescription sunglasses are even more important for maintaining good eye health. Here are 10 compelling reasons why you should consider getting prescription shades.

10 Reasons Why Prescription Sunglasses Are Essential for Eye Health

1. Block Harmful UV Rays

UV rays can damage the cornea and retina over time, potentially leading to conditions like cataracts, macular degeneration, and growths in the eye. According to the American Optometric Association, excessive UV exposure can even cause "photokeratitis, akin to a 'sunburn of the eye'." This is severely painful and can lead to temporary vision loss.

Prescription sunglasses with 100% UV protection effectively shield your eyes from these dangerous rays year-round. Don't rely solely on hats or regular eyeglasses for adequate safeguarding. The wrap-around design of sunglasses optimally protects the sensitive tissue around your eyes that hats miss.

Without adequate UV protection, accumulated photochemical and retinal damage from the sun's rays can advance to macular degeneration. UV exposure early in life significantly raises a lifetime risk of cataracts and other ocular diseases.

So don't take chances with cheap shades. Invest in the best prescription sunglasses with UV-blocking features to protect long-term eye health. They're an essential shield against harmful UV rays.

2. Protect Against Debris 

When outdoors, our eyes are vulnerable to blowing dust, dirt, sand particles, and other irritants. While prescription glasses may filter some of these out, only robust sunglasses can optimally defend against eye injuries and inflammation from such debris. 

Wearing shades reduces risks. And in windy conditions, tightly fitting wrap-around sunglasses offer even better particle protection.

3. Enhance Comfort and Convenience

Trying to wear eyeglasses under sunglasses can feel awkward and uncomfortable. They might not fit together very well. 

With prescription sunglasses, you get the corrective lenses you need along with protection from bright light - all in one sleek, integrated pair of shades. No more juggling two sets of spectacles.

4. Stay Updated on Changing Vision 

As we age, our vision prescriptions require more frequent updates to address changes in our eyes. Wearing outdated lenses can lead to unnecessary eye strain, headaches, and blurriness. This is especially relevant for people over 40.

Prescription sunglasses should align with your current correction needs. Schedule an annual eye exam, and upgrade your shades accordingly for peak performance. Don't let old lenses undermine your health perks.

5. Enhance Performance During Sports

During outdoor sports and intense activities, robust eye protection takes priority. Prescription sports sunglasses with impact-resistant lenses shield your eyes from racquetballs, golf balls, and other hazardous high-velocity objects.

The securely wrapped frames also prevent normal sunglasses from flying off your face. This allows you to focus on performing at your best.

6. Maximize Visual Clarity With Polarization

The sun glaring off snow, water, or other surfaces can be blinding. Squinting strains your eyes and causes headaches. Polarized prescription sunglasses substantially reduce glare and eye fatigue.

By filtering out specific light wavelengths, these specialized shades optimize visual clarity. This makes activities like driving, fishing, hiking, and beach trips more pleasurable and safer.

7. Conquer Nearsightedness Outdoors

For people with myopia (nearsightedness), seeing objects clearly in the distance is challenging without corrective eyewear. But switching between prescription glasses and sunglasses can be tiresome.

Prescription sunglasses seamlessly bridge this vision gap, allowing you to read a book at the beach or glance at a trail map while hiking. No more hassling with multiple sets of spectacles.

8. Accessorize With Advanced Lenses

From trendy mirrored lenses to functional anti-reflective treatments, prescription sunglasses now offer varied lens upgrades beyond basic UV protection.

Options like impact/scratch resistance, hydrophobic coatings, and progressive bifocals provide specialized benefits. Discuss your priorities with an optometrist to accessorize with the ideal shades.

Here's a table that shows the benefits of different lens features for easy comparison:

9. Give Your Eyes a Break From Contacts

On days when you don't want the hassle of inserting contact lenses, prescription sunglasses are a convenient alternative. They allow your eyes to breathe while still letting you see clearly outside.

Having a pair of prescription shades means you don't have to sacrifice vision, comfort, or style on your contact lens holidays.

10. Say Goodbye to Clip-On Shades 

Rather than wearing ill-fitting clip-on shades over your prescription glasses, get dedicated prescription sunglasses. This eliminates uncomfortable pressure on your nose and provides more effective UV protection. 

For maximum practicality and aesthetics, custom prescription lenses attached directly to the sunglass frames offer unparalleled convenience.

Key Takeaways 

Prescription sunglasses may cost more upfront than drugstore shades, but they're a smart investment in your long-term eye health and daily comfort. Here are some key reasons to spend on customized prescription shades: 

  • They provide durable UV protection explicitly tailored to your eyes, filtering out up to 100% of UVA and UVB rays.
  • The frames and lenses are designed to seamlessly fit your face, reducing pressure points that can cause headaches. 
  • The optics are calibrated precisely to your prescription for maximum visual clarity—no squinting or eye strain.
  • You'll avoid the hassle of losing sunglasses due to an inadequate fit. Prescription models stay snugly in place.
  • Advanced lens treatments like polarization and anti-reflective coatings optimize eye comfort.
  • Your sunglasses will always match your current vision needs when you get new prescriptions.
  • It spares you the awkward look and feel of wearing clip-ons over your regular glasses.

The right prescription shades are an investment that pays off every time you head outside. You get protection, clarity, style, and convenience in one sleek accessory. So don't compromise - see your optometrist and safeguard your vision with custom shades.

Frequently Asked Questions

1. Are all prescription sunglasses capable of blocking 100% of UV rays?


Unfortunately, not. When selecting prescription shades, it's critical to verify that they offer 100% UV protection or a UV400 rating to safeguard your eyes. Not all lenses inherently filter out UVA and UVB rays.

2. How often should I update my prescription for sunglasses?

Eye doctors recommend getting an annual eye exam and updating your prescriptions accordingly. This is especially important after age 40 when vision changes more rapidly. Don't wear sunglasses with outdated prescriptions.

3. What's the difference between regular and polarized prescription sunglasses?

Polarized lenses use a special filter to further reduce reflective glare from surfaces like water or snow. This minimizes eye strain and improves visibility. If you're outdoors frequently, polarized prescription shades are ideal.

Over 50? Take Care of Your Eyes

As individuals age, especially those over 50, their eyes naturally become more susceptible to a range of conditions and sensitivities, making protection against harmful UV rays even more crucial. Prescription sunglasses provide the dual benefit of corrective lenses tailored to an individual's vision needs while also offering the protective shield of sunglasses. This ensures that people can enjoy clarity of vision without straining their eyes in bright environments, reducing the risk of exacerbating age-related eye conditions like macular degeneration or cataracts.

Moreover, the design of prescription sunglasses has evolved to cater to the aesthetic preferences of older individuals. This means that they don't have to compromise on style while prioritizing their ocular health. The glare from water, pavements, or other surfaces can be particularly intense and discomforting for aging eyes. Prescription sunglasses effectively mitigate this issue, allowing those over 50 to engage in outdoor activities, whether it's reading a book by the beach or driving, with enhanced comfort and safety.

Visit Your Eye Doctor

Regular visits to the eye doctor are paramount, especially as one ages. With time, subtle changes can occur in one's vision, and certain eye conditions might develop without immediately noticeable symptoms. By seeing an eye professional regularly, potential problems can be detected early, ensuring timely interventions and preserving optimal eye health. 

Furthermore, these check-ups provide an opportunity to update prescription needs, ensuring that eyewear, whether daily glasses or prescription sunglasses, remains effective and comfortable. In essence, maintaining regular eye appointments is a proactive step in safeguarding one's vision and overall ocular well-being.

Editor's Note

Retirement planning, often centered on financial securities like 401(k)s and savings accounts, must evolve to address the challenges associated with aging and long-term care. As the American population continues to age, the potential need for assisted living, home health care, and other long-term services looms larger. Ignoring these realities can jeopardize one's hard-earned savings. It's not just about ensuring a comfortable retirement; it's about safeguarding assets from the skyrocketing costs of health care services in later years.

Long-Term Care Insurance emerges as a pivotal solution in this context. By incorporating LTC Insurance into retirement planning, individuals can create a protective barrier around their savings. Policyholders can lean on their LTC coverage instead of drawing from their 401(k) or depleting other assets to finance unforeseen health care needs. This not only ensures financial stability but also grants peace of mind, knowing that one's nest egg remains intact.

Moreover, the benefits of an LTC policy extend beyond mere financial security. One of the unspoken challenges of aging is the strain it can place on family dynamics. Loved ones often bear the brunt of caregiving duties, which can be emotionally, physically, and financially taxing.

With an LTC Insurance policy, families can hire professional care, allowing them to focus on cherished moments and maintain their roles as sons, daughters, or spouses rather than primary caregivers. It's a compassionate approach that prioritizes both financial wellness and family bonds.

The time to add coverage is when you are still enjoying good health. Most people get coverage in their 40s or 50s, but if you have good health, you still have opportunities to get affordable coverage in your 60s and beyond.

Unlock the Best LTCI Coverage with a Specialist's Expertise

Navigating the landscape of Long-Term Care Insurance can be intricate and, at times, overwhelming. This underscores the importance of seeking guidance from a dedicated LTC Insurance specialist, particularly one who represents the top companies and boasts substantial experience in long-term care. 

Tapping into their expertise can ensure you secure the most suitable coverage tailored to your individual needs while benefiting from a broad overview of the market's best offerings.

A qualified specialist will match your age, health, and other factors to provide accurate quotes from all the top insurance companies so you can make an informed decision. 

An independent LTC Insurance specialist affiliating with the industry's leading companies provides an invaluable edge: access to diverse policies offering long-term care benefits. Each insurance company offers varied features, benefits, and pricing structures. 

By working with a well-connected specialist, you're not confined to the limited offerings of a single insurer. Instead, you gain the advantage of comparison shopping, ensuring you get a policy that aligns with both your care preferences and budgetary considerations.

Moreover, the intricate nuances of long-term care can be challenging for the average person to grasp fully. An experienced LTC Insurance specialist brings a wealth of knowledge about the evolving trends, policy stipulations, potential pitfalls, and federal and state regulations.

A specialist will guide you through complex terminology, assist in forecasting potential care needs, and even advocate on your behalf when issues arise. In essence, partnering with a seasoned specialist in long-term care is not just about purchasing a policy; it's about making an informed, strategic investment in your future well-being.
