Wearing sunglasses is more than just a fashion statement. It’s also the easiest and most eye-healthy habit you can start building right now.
Sunglasses are very important for children and adults to protect their eyes from sun damage and maintain healthy eyesight throughout life. There are many brands of sunglasses available at Tuaco, and different types of lenses which offer varying degree of protection from the damage caused by sunlight and UV rays.
Although many people believe that sunglasses protect vision thanks to the dark tinted lenses which place the eyes in the shade, there are other ways in which sunglasses contribute towards preserving eye health.
To enjoy adequate protection from sun damage, your sunglasses must block nearly all of the sun’s UV rays.
Sunglasses give you an indication of how well they block out UV rays and you should always aim to purchase a those that protect from 99 to 100% if UV-A and UV-B waves.
You can ascertain that you bought a high-quality pair of sunglasses by purchasing those labelled as UV 400, which means they can block all waves up to 400 nanometres in wavelength, thus covering all rays in the UV-A and UV-B spectrum.
The differently coloured tints on the lenses in your sunglasses play an important role in filtering light out.
Amber lenses, for example, block out most of the blue light, which scientists have determined to be harmful to vision in large quantities and could increase the risk of eye diseases like macular degeneration.
Blue-blockers, are a very popular type of lenses, among hunters, pilots, boating and enthusiasts and anybody who spends a lot of time outdoors, especially since they also increase contrast.
Polarised lenses have become very popular in recent years as more people discovered the benefits of these types of sunglasses, going from being restricted to outdoor activities enthusiasts, to a mainstream choice in eyewear.
Polarised lenses reduce reflected glare from surfaces such as roads or smooth bodies of water. Light bouncing off these surfaces is generally horizontally polarised, meaning that light rays travel horizontally through air and can achieve a dangerous intensity which people experience as glare.
Glare can be very distracting and cause accidents, especially while driving or engaging in high-risk activities. Polarized lenses contain a special filter which eliminates this type of intense reflected light, reducing glare and improving comfort and visibility in these situations.
People who can benefit the most from wearing polarised sunglasses include drivers, bikers, boating enthusiasts and joggers, who can enjoy a clearer view of what’s in their environment in bright conditions
Polarised sunglasses can also be worn indoors by people who are light-sensitive, such as those who have recently undergone cataract surgery, as well as office workers who are continually exposed to bright light coming through windows.
Anti-reflective coating is applied on most sunglasses in order to cut down the glare that is caused by light reflecting off the back of the lenses.
Mirror-coated lenses reduce the amount of light that enters your eyes through your sunglasses’ lenses. Also known as flash coating, it is applied to the front surface of the lens and diminishes the discomfort caused by light reflecting off surfaces in bright environments.
One of the less obvious ways how sunglasses protect your eyes from sun damage is through their design.
Sunglasses with a wraparound shape block any stray sunlight that enters from above, below or beyond the edges of the lenses, keeping your eyes in the shade at all times.
