There are many different types of contact lenses, and it’s always best to consult an eye doctor before deciding which is best for you. One of the biggest decisions will be whether to choose soft contact lenses (SCLs) or hard ones, which are also known as rigid gas permeable lenses (RGPs).

What Are They Made Of?

Soft contact lenses are made of flexible plastics known as hydrogels. Hydrogels can absorb a large amount of water, which keeps them supple and doesn’t dry the eye. Silicone is sometimes added to hydrogel lenses to increase the amount of oxygen that can reach the cornea. Like hydrogels, the various plastics used to make rigid contact lenses are all gas permeable, meaning oxygen can reach the eye.

How Do They Help Eye Conditions?

How Will a Doctor Recommend One?

Your eye doctor will base their recommendations on your particular condition as well as your lifestyle and lens preference. Soft contact lenses are easier to get used to and stay in place better, while harder lenses allow sharper vision and need less follow-up care.
