Definition |
| |
Made from flexible plastic, these lenses absorb water and thus enable greater amounts of oxygen to pass through the lens to the cornea. Soft lenses are more comfortable for most wearers than hard lenses, and most lenses prescribed today are a version of a soft lens. They vary in design depending on the type of materials and required refractive correction. |

These may be in form of :- |
| |
- Extended wear contact lenses: made of material designed to last 2-4 weeks.
- Daily disposable lenses: although generally more expensive, carry a lower infection risk.
- Toric contact lenses: correct moderate astigmatism. They are available in both rigid and soft materials.
- Generally, contacts should be removed at bedtime due to risk of infection and risk of contact lens intolerance.
