Types of contact lenses
Soft lenses
Thin and pliable, soft contact lenses have the ability to conform to your eye for a snug fit.
Polymethyl methacrylate (PMMA)
Old-fashioned hard contact lenses. These lenses are made of a hard plastic material, and while they provide good vision, they can be very uncomfortable and many people find them difficult to get used to.
Silicone hydrogel lenses
Initially introduced in 2002, silicone hydrogel contact lenses are the most popular contact lenses in the United States. They’re a more advanced soft lens that’s permeable, allowing oxygen to reach your cornea.
Hybrid contact lenses
A combination of hard and soft lenses for better vision and comfort, the center of the hybrid contact lens is made up of a hard plastic material to give you better vision, while the edges are soft for comfort.
Gas permeable lenses
These are hard contact lenses that are permeable, allowing oxygen to reach your cornea. Although less comfortable than soft lenses, gas permeable lenses provide sharper vision, and you may prefer them if you have astigmatism.
Customized contact lenses
Providing another method of self-expression, contact lenses are also available in different eye colors and designs.
