Just as a natural sunscreen can be beneficial for your vision health, sunglasses have their place in the health industry too. If you are skiing or out on the water, wearing sunglasses can help to protect your eyes from sun damage. However, I personally avoid wearing sunglasses on many occasions other than this, for reasons explained below.
In the first place, we need to declare how the Sun can damage your eyes. Just like your skin on any part of your body, your eyes are susceptible to damage from too much sun exposure too. The skin around your eyes, including the eyelids, is among the most sensitive and thinnest on your body, making it vulnerable to age spots and wrinkling from excessive exposure to UV rays. Sun damage may cause the conjunctiva. Namely, the thin membrane is there to cover the white part of your eyes. Conjunctiva means your eyes became inflamed and irritated.
The cornea is even more sensitive as it can be sunburned, causing acute pain and temporary blindness. However, chronic exposure to the sun can lead to cataracts, especially if your diet does not contain lots of antioxidants.
If your eyes are blue-colored, you may want to avoid sunlight even more as your eyes are more susceptible to UV-induced damage.
As for the time when you may need serious protection for your eyes, not every sunglasses out there are created equal. You cannot even use price tag as an indicator of quality as many of the high-priced brands cost a plethora of money because of its brand, not function. Ray Ban Sunglasses Inc is a good example of such a brand that's more popular because of its fashion status than the actual function of their glasses. Generally speaking, in order to ensure you are getting a quality pair of sunglasses you should look for:
- Glasses that says 99-100% UV absorption or UV 400. Avoid glasses that simply say "absorbs UV" because these sunglasses are not reliable
- Darker lens colors don't always mean better UV protection as UV the UV protection can be of any color
- Be careful of sunglasses called sunware or Eyeware (This one is especially interesting as Sunglass Hut some of their products sell under the "Eyewear" label.)
As I have mentioned at the beginning of the post, I rarely wear sunglasses. I actually wear sunglasses only for special occasions, usually when I'm skiing or surfing. Under these conditions, the water or snow greatly magnifies the sunlight and may even cause slight pain. That's why I choose some sunglasses from Oakley Sunglasses collection and wear these when I really need them. On an average nice sunny day, the last thing you want to do for your vision is to wear sunglasses. You may ask - why? Because sunglasses will probably be blocking potentially beneficial wavelengths of the light from reaching your eyes. Instead of wearing sunglasses, you may want to opt for a cap to protect your face and eyes from the sunlight. If you really want to protect your eyes, the cap is your best friend. On the other hand, if your eyes are really sensitive to the sunlight, you may want to ask a doctor to get you a pair of prescription sunglasses.
