History of Contact Lenses

Contact lenses may be grouped into two main types; hard gas permeable contact lenses, and soft hydrogel contact lenses.
Leonardo da Vinci is frequently credited with introducing the general principle of hard contact lens. He described a method of directly altering corneal power by submerging the eye in a bowl of water. Leonardo, however, did not suggest his idea be used for correcting vision as he was primarily concerned with learning about the mechanisms of accommodation of the eye.

What Type of Contact Lenses Are Right For Your Eyes?

Contact lenses are thin discs that when placed over the cornea of the eye serve to act as a substitute for eyeglasses. The conditions that are corrected by contact lenses are the same as the conditions corrected by eyeglasses and include the following:
• Astigmatism (distorted vision)• Myopia (nearsightedness)• Hyperopia (farsightedness)• Presbyopia (need for bifocals)
Just like no two sets of fingerprints are identical, no two pairs of eyes are exactly alike either. Because of this, there are different types of lenses for different types of eyes. Read below to find out which type of contact lens is right for you.
