The best defence against UV damage to eyes is wearing quality sunglasses. Ultraviolet rays cause both short and long-term damage, which include macular degeneration and temporary vision loss. For eyewear that protects, International Eyewear recommend that you should check for the following in your next sunglasses purchase.
For summer outdoors, on a road trip, or on a boat, you should buy polarised sunglasses. These glasses remove the glare that occurs when sunlight reflects on flat surfaces. These include snow, paved roads, and even water. They provide clearer vision and objects can be seen better.
Contrary to what most people believe, darker sunglasses do not equal more protection. Instead, the colour depth of the shades purchased will depend on the kind of activities being done. Grey, brown, or green shades are the most preferred colours for most activities.
Not all sunglasses protect from UV rays. Always check if the glasses have 100% UV rays protection. A licensed optometrist will make sure that the glasses have the right protection.
Check Visible Light Transmittance (VLT). VLT is the amount of light that can go through an eyewear’s filter. The higher the VLT, the better is the protection against glare. For well-lighted environments, you could buy glasses with a 20 percent VLT.
Many people consider wearing sunglasses as a fashion statement. However, eyewear is not merely for aesthetics, but also for health.
