A Guide to Sunglasses
Most people pull out their sunglasses at the first sign of the sun peeking through the clouds, which is a smart move. However, some people do it simply because it is the “thing to do,” not fully understanding just how much sunglasses do for them. In addition to blocking the bright sun and helping you to see, sunglasses also play a vital role in keeping your eyes healthy for years to come. Our team at Optica 20/20 San Antonio can help you find prescription or non-prescription sunglasses to keep your eyes safe.
How Does the Sun Affect Your Eyes?
The sun emits UV or ultraviolet rays, which are invisible to the naked eye but can be very harmful. UV rays can damage the eyes just like they damage the skin. They can cause cataracts, which impact many things such as night vision and the ability to see colors. UV rays can also damage the retina, the eye’s tissues, and the cornea. Furthermore, they can increase the risk of macular degeneration and other eye conditions. Wearing a good pair of sunglasses can go a long way in preventing these issues.
Choosing the Right Sunglasses
When choosing sunglasses, it is important to be sure you pick a pair that will actually protect your eyes. Many sunglasses that you can pick up at a local convenience store or retailer provide little to no actual protection. In addition to finding a pair you feel are good and look good in, you want to look for lenses that block 99 or 100 percent of UV rays.
The lenses should include both UVA and UVB protection. Aim for sunglasses with a label that states “UV 400” for the best protection. Blocking UV rays is important, but don’t forget you need to block the sun’s glare as well to see clearly. In addition to the “UV 400” label, look for a pair that blocks at least 75 percent of visible light.
Should I Get Polarized Lenses?
Polarized lenses are great for some activities, but they are not necessary for everyone. You would want to wear them if you fish, boat, golf, jog, or participate in any other activity where glare will bounce off the surface in front of you. They can also be great for driving. Although polarized lenses aren’t necessary for every daily activities, having a pair handy comes in handy. At Optica 20/20 San Antonio, we are happy to help you determine if they are a good option for your needs.
