Luckily, a good pair of shades can keep those harmful rays at bay. Whether you're photophobic or just want to look cool, we've got the scoop on picking stylish specs that shield sensitive eyes. Sunglasses come in all shapes and sizes now, with options tailored to different eye conditions and ages. So read on to learn how the right shades can fend off eye problems down the road. Your future eyes will thank you!

Common Eye Conditions From Sun Exposure

UV radiation from the sun can cause serious damage to your eyes over time. Prolonged sun exposure leads to conditions like cataracts, age-related macular degeneration, and growths on the eye like pingueculae and pterygia.

Without protection, the UV rays penetrate deep into your eyes. Over days and years of sun exposure, the UV radiation builds up and breaks down the proteins and tissues in your eyes, causing irreparable harm. The effects tend to worsen with age as your eyes become more sensitive and less able to repair damage.

The best way to protect your peepers is by wearing sunglasses that block both UVA and UVB radiation whenever you're outside during the day. Look for sunglasses that specifically say they block 100% of both UVA and UVB rays. Large framed styles and wrap-around sunglasses provide the most coverage.

For those with sensitive eyes or conditions like cataracts, macular degeneration or pterygia, high-quality polarized sunglasses can reduce glare and make being outside more comfortable. Photochromic lenses that automatically darken in sunlight are also helpful as they reduce the need to switch between regular glasses and sunglasses.

As you get older, especially after age 60, it's critical to protect your eyes from the sun. Age-related changes in your eyes make them even more vulnerable to damage. Wearing sunglasses, limiting sun exposure during the middle of the day when the sun is strongest, and wearing hats with brims can all help prevent vision loss and keep your eyes healthy for years to come.

Protecting your vision starts today. Make wearing sunglasses a habit and give your eyes the protection they deserve against the sun's harsh UV rays. Your future self will thank you.

How Sunglasses Protect Your Eyes

  • Photokeratitis: Also known as snow blindness, photokeratitis is caused by UV radiation from the sun (or snow!) damaging the cornea, the clear front cover of your eye. Symptoms like a gritty feeling, pain, redness, and temporary vision loss can show up within 6-12 hours of sun exposure. The good news is it's usually temporary, but it's still no fun. Sunglasses can help prevent this painful condition.
  • Pterygium: Prolonged sun exposure over many years can cause fleshy growths on the white of the eye that can eventually spread onto the cornea. These growths, known as pterygia, can lead to astigmatism, chronic inflammation, and vision loss if left untreated. Sunglasses are key to avoiding pterygium in the first place.
  • Macular Degeneration: Sun exposure is a major risk factor for age-related macular degeneration (AMD), a leading cause of vision loss for those over 65. Ultraviolet (UV) light can damage the macula, the part of the retina responsible for sharp, central vision. Sunglasses that block both UVA and UVB rays can help prevent sun-related AMD and slow the progression of the disease.
  • Cataracts: A cataract is a clouding of the eye's natural lens, and excess UV radiation exposure is a significant risk factor. Sunglasses absorb UV rays before they can damage the lens and contribute to cataract formation. Wearing sunglasses, especially in youth and middle age, may help delay the onset and progression of cataracts.

Finding the Right Sunglasses for Your Needs

As you get older, it’s essential to protect your eyes from the sun's damaging UV rays. UV exposure is cumulative over your lifetime and can lead to vision loss and serious eye diseases like cataracts, macular degeneration, and growths on the eye. The good news is, wearing sunglasses that block 100% of UVA and UVB rays can help prevent this damage and keep your eyes healthy for years to come.

Prevent Premature Aging: Squinting in bright light can cause crow's feet and wrinkles around your eyes over time. Sunglasses relax your eyes and prevent excessive squinting, keeping your eyes looking youthful. They also block the sun's aging effects on the delicate skin around your eyes.

Reduce Eye Strain: Bright sunlight strains your eyes, causing headaches, fatigue, and discomfort. Polarized sunglasses eliminate reflected glare from surfaces like water, snow, and roads. This makes it more comfortable for your eyes to be outside in intense light and reduces eyestrain.

Protect Light-Sensitive Eyes: If you have light-sensitive eyes from a condition like iris albinism or iritis, sunglasses are essential for your vision and comfort. Specialized sunglasses that block all UV radiation and most bright blue light can make it possible for you to be outside during the day without pain or vision issues.

Sunglasses are such a simple solution with huge benefits for your long-term eye health and vision. As styles and lens technology improve each year, there’s no reason not to make wearing sunglasses a habit and give your eyes the protection they deserve. Your future self will thank you.

Sunglasses FAQs: Your Top Questions Answered

With so many options, choosing sunglasses can be tricky. The most important factors are protecting your eyes and visual health. Consider your needs and sensitivities to find the perfect pair.

UV Protection: Look for sunglasses that block UVA and UVB rays, which can cause cataracts, macular degeneration, and skin damage. For most people, look for glasses that block 99-100% of both UVA and UVB rays. Those with light-colored eyes or a family history of eye disease should aim for maximum UV protection.

Lens Material: Plastic lenses are lightweight, shatter-resistant and block UV rays. Polycarbonate lenses are a good plastic lens option. Glass lenses tend to be more scratch-resistant but can be heavy. Photochromic lenses darken in UV light and lighten in low light, reducing the need to switch between sunglasses and regular glasses.

Lens Color: For most general use, grey lenses reduce brightness without distorting colors. Brown lenses enhance color contrast and depth perception. Green lenses are good for outdoor activities like golfing. Polarized lenses reduce glare from reflective surfaces like water or snow. They come in grey, brown and green tints.

Frame Style: Choose a frame style that fits comfortably and suits your needs. Wrap-around frames provide the most UV protection for your eyes and surrounding skin. Sport frames are lightweight but durable for an active lifestyle. Oversized frames are stylish but may not offer as much protection or be suitable for smaller faces.

Special Considerations: Those with sensitive eyes or conditions like glaucoma may need specialized tinted lenses to reduce glare and light sensitivity. Talk to your eye doctor about lens options that suit your needs. As we age, our eyes become more sensitive to UV damage and glare. Larger frames, polarized lenses and maximum UV protection are important for older adults.

Protecting your vision for years to come starts with finding sunglasses tailored to your needs and lifestyle. Talk to your eye care professional if you have any concerns about UV exposure or eye health. They can recommend options to keep your peepers shaded and your vision clear.
