These lenses are comfortable to wear and must be replaced monthly, weekly or daily depending on the type you choose. Soft lenses are often recommended for sports because they fit closer to the eye and are more difficult to dislodge. They can provide correction for most prescriptions including astigmatism. Today, with the introduction of newer materials like silicone hydrogels, which allow more oxygen to the eye, patients find it easier than ever to wear soft lenses comfortably.
If you thought you couldn’t wear contacts because you require bifocal lenses then these are for you. In both soft and GP designs, multifocal lenses offer patients both distance and near vision correction just like a pair of bifocal glasses.
Gas-Permeable (GP) Lenses
Made of moderately flexible plastics, GP lenses offer sharp vision and correct most vision problems. They are more durable than soft contact lenses and can be easier to handle and care for but require a longer adaptation period and consistent wear to maintain adaptation.
Silicone hydrogels are soft contact lenses that have high oxygen permeability and are comparable to GP lenses.
