he first choice when considering contact lenses is which lens material will best satisfy your needs. There are five types of contact lenses, based on type of lens material they are made of:
Soft lenses are made from gel-like, water-containing plastics called hydrogels. These lenses are very thin and pliable and conform to the front surface of the eye.
Silicone hydrogel lenses are made of an advanced type of soft contact lens material that allows more oxygen to pass through the lens and reach the front surface of the eye. Silicone hydrogel contact lenses are now the most popular type of contact lenses.
