Historically spectacle lenses or 'pebbles' used to be made from a glass material or even naturally occuring pebbles.
- Modern lenses are made from much lighter and safer materials (only rarely is glass used for modern lenses).
- Spectacle lenses that are worn for sport or work should be made from materials that will provide protection to the eyes.
- New lens materials are constantly being developed to give you better vision and more comfortable specs.
Deciding which material is right for your lenses is a complex decision, and needs to be made through discussion with your Dispensing Optician.
