Oh for the days when there were just glass or plastic lenses! Now there are 4 different basic types of glass and 4 different basic types of plastic. A comparison of the thickness of 3 types of plastic can be seen below. Add to that polycarbonate and other safety materials and you can see how complicated it has become. Not only that but there are special lens “forms” which are designed to minimise thickness. After that you can consider photochromic materials which change in the sun and all the various colours of tinted lenses available.
This picture shows a comparison of different lens forms and materials
Plastic lenses are often supplied with a hard coat to minimise scratching and most lenses can be given an anti-reflection coat.
There are single vision, bifocal and varifocal lenses plus vocational lenses for example for computer use. There are even special lenses if you need bifocals but spend your life screwing screws into ceilings! But don’t worry – tell us your problems and we will try to help – as long as they are connected with your eyes!
You may now begin to understand why if you ask “how much does it cost for a pair of glasses?” you will not receive a straight answer.
Whilst we normally advise Rodenstock lenses, we can supply many other makes where these are either better or if you prefer them, including Zeiss, Nikon and Essilor (Varilux).
