Sunglasses
Before buying a new pair of sunglasses it's important to consider their functionality just as much as their fashion sense. What sunglasses can do to protect the health of your eyes is just as important as how they make you look.
The sun's UV rays can damage your eyes and lead to eye diseases later in life such as cataracts and they may play a role in the development of macular degeneration.
So, what are the most important things to look for?
Regardless of whether you currently wear eyeglasses or contact lenses you'll want to get polarized sunglasses. Polarized lenses contain a special filter that blocks the intense reflected light from surfaces such as flat roads or smooth water. This reflected light causes an intensity of light often called glare. Polarized sunglasses allow you to see more clearly without fighting the glare.
Photochromic lenses are a popular option for people who spend a lot of their days going in and out. These lenses have chemical properties that change based upon the amount of light. They darken when you're outdoors exposed to sun and light and lighten when inside.
Contact lens wearers may find wearing prescription sunglasses is sometimes a far more practical alternative outdoors. Prescription sunglasses are available for virtually any lens prescription, including bifocal and progressive lens options if you are presbyopic and need lenses to help you read.
