Hard lenses are made by silicone polymers which facilitate the flow of oxygen to your eyes.

In Dublin these lenses are advantageous if there is any irregularity in the shape of the cornea. For example, in a situation called keratoconus, where the cornea assumes an abnormal shape. According to opticians these lenses tended to be uncomfortable because they allowed no air passage.
