Hard lenses are lenses that retain their form, so they do not have much give. This makes them extremely appropriate when the eye declines in strength. Because of the developments in ophthalmology, hard lenses have a longer lifespan and allow a lot of oxygen to pass through, which benefits the health of the eye. A standard hard lens usually corrects the cylinder correction of C -0.50 / C-0.75. When a hard lens has a reading part, this will be concentric.
