Contact lenses can be worn to correct various vision problems including myopia, hyperopia, astigmatism, and presbyopia. While soft contact lenses are prescribed most often, there is another type of lens available – a rigid gas permeable (RGP) lens, sometimes called a hard contact lens, can also be used for vision correction.
These two types of lenses are made out of different materials and offer different advantages and disadvantages, but both can be used to correct vision.
Hard contact lenses used to be made out of PMMA or polymethylmethacrylate, acrylic glass, or even lucite. However, in the 1970s, hard contact lenses switched over to rigid gas permeable lenses. RGP lenses incorporate silicone and are more flexible than the original hard lenses, which makes them better for the cornea since they let more oxygen permeate the lens.

Disadvantages of RGPs or Hard Contact Lenses:
Made of a gel-like plastic, called hydrogel, soft contact lenses are combined with water to allow plenty of oxygen to reach the cornea while also being comfortable and flexible. There are several different types of soft contact lenses that can be worn for varying amounts of time including dailies, weeklies, bi-weeklies, and monthlies.

There are plenty of things to consider when deciding which type of lens you should choose. Your lifestyle, your prescription, and your eye conditions should all be factors. Your eye doctor can help you determine which type of lens will be the best fit for your eyes.
