Description

A pair of gas permeable scleral contact lenses made from gas permeable fluoroscilicone acrylate, which has good optical qualities, biocompatibility and allows the transfer of oxygen to the eye. Scleral contact lenses only touch the sclera, the white part of the eye and are used when the cornea has become irregular due to trauma or eye health conditions. This type of lens is always bespoke. The back surface of the lens is made to fit the eye. The front surface corrects the prescription. The trapped tear lens between the contect lens and the eye neutralises corneal irregularities. The lenses are made from buttons of the material wich are lathed down to 0.2 or 0.3 mm thick to make bespoke contact lenses. Each lens has a slight coloured tint denoting which eye they are made for. The lenses are contained in a dual compartment polypropylene case with screw tops. The measurment listed is for the lenses.
