What are the different kinds of lenses that are available?
With so many lenses available, it’s a good idea to ask a professional optician for help when choosing sunglasses. Different tints can help you see better in certain conditions, and a knowledgeable optician can help you choose sunglass tints that are best suited for your needs. Blue-blockers block blue light and usually have amber lenses. Some evidence indicates blue light is harmful, and could increase risk of eye damage from diseases such as macular degeneration. These lenses are popular among skiers, hunters, boaters and pilots who use them to heighten contrast. Both polarized lenses and anti-reflective coating cut reflected glare. Polarized lenses in particular are popular with those who play water and snow sports. Anti-reflecting coatings reduce glare caused by light reflecting off the back surface of your sunglass lenses.
