The basic soft quality of soft lenses comes from their water absorbency. They are usually gas-permeable, allowing oxygen transport to the cornea. This softness and permeability make them considerably more comfortable than hard lenses, and many wearers can adapt to them almost at once. These qualities can be advantageous to wearers, but they come at the expense of some visual clarity. Soft lenses, which may contain anywhere from 30 to 90 percent water, can be very flexible, but what is called their “bag of water” nature has an effect on refraction, yielding less clear images than provided by hard lenses. Additionally, high water content lenses are usually fragile and easily torn. Reducing the water content in order to increase acuity and durability, however, sacrifices comfort. Reducing the plastic content to increase acuity by making a thinner lens usually increases fragility. These tradeoffs are the major problem with soft lenses.

Soft lenses take little getting used to when wearers first start wearing them.

Soft lenses provide less sharp vision than most hard lenses.

Due to their high level of moisture, soft lenses tend to tear easily.

The thinner soft lenses are, the more oxygen they allow to reach the cornea.
