Spectacle lenses are manufactured from a variety of different materials, including plastic, glass and polycarbonate. Plastic is the most popular choice as it is lighter than glass and safer to wear.

The main types of lenses

Single Vision Lenses are the simplest and most popular form of lens. They are used to correct single vision deficiencies in long or short sightedness.

Bifocal Lenses contain two optical corrections for patients requiring assistance in both near and long distance vision. The two sections are clearly visible by the distinctive section on the lens. The combination of both prescriptions eliminates the need for two pairs of spectacles.
