Do you desire thinner and lighter lenses? Most of today's eyewear choices are made of plastic or metal with rims thinner than the lens. Sometime eyewear has no frame at all and features rimless mountings. In either case, the lens edges are highly visible and thicker edges can detract from the appearance of your eyewear.
The good news is that a variety of new plastic materials are available to provide thinner and lighter lenses. This means less lens material can be used to correct the same amount of prescription. In addition to looking thinner, your lenses will also reduce the magnified "bug-eye" or "Coke-bottle" look often caused by thicker lenses.
Ask an optician about which lens material will be best and most comfortable for you!
