Glass is heavier than all other lens materials. It is recommended to treat glass lenses with an impact-resistance treatment as they shatter easily.
These lenses provide distance vision correction in patients with nearsightedness, farsightedness or astigmatism. This type of lens is available in all materials.
These serve the same purpose as a progressive lens but with visible lines on the lens. A large portion of the lens is used for distance vision; the centre portion for intermediate vision; and the bottom portion for near vision.
