Extended Wear Contacts
Extended Wear Contacts

Most extended wear (EW) contacts are thinner than daily wear lenses and are made of silicone hydrogel. This advanced soft lens material enables EW lenses to "breathe" better than daily wear lenses, allowing more oxygen to reach the cornea. This is especially important when lenses are worn continuously for extended periods of time.

Hard Lenses
Hard Lenses

Hard Contact Lenses. Hard contact lenses are generally known as semi-rigid gas permeables (RGPs)and they are now made of plastic-like material, although originally they were in fact made of glass.

Multifocal / Bifocal

Multifocal and bifocal contact lenses are designed for people with presbyopia who have trouble focusing on close-up objects. They work by combining correction for distance and near vision into the same contact lens. Multifocal lenses have improved significantly in recent years due to better technology.

Rigid gas Permeable (RGP) Lenses
Rigid gas Permeable (RGP) Lenses

Gas permeable contact lenses are also called RGP (Rigid Gas Permeable) contact lenses, and oxygen permeable lenses. GP designs are differentiated primarily by size. For many years virtually all GP lenses were fitted significantly smaller than the corneal diameter, typically 9 to 10 mm in diameter.

Spherical Contacts
Spherical Contacts

Spherical contact lenses have the same lens power throughout the entire optical part of the lens to correct myopia (nearsightedness) or hyperopia (farsightedness). Toric soft contact lenses have different powers in different meridians of the lens to correct astigmatism as well as nearsightedness or farsightedness.

Toric Contacts
Toric Contacts

A toric lens is a contact lens that's shaped in a particular way. Standard contact lenses have a spherical surface: think of a slice of the side of a beach ball. A torus, in contrast, is a geometric shape that looks like a donut.
