If you’re brand new to contacts or thinking of switching over from glasses, the thought of putting tiny corrective lenses on your eyes might cause some apprehension. How do these almost invisible lenses even work? It’s pretty amazing stuff, and you should read our article on the history of contact lenses to see how far we’ve come. (Teaser: It used to involve submerging one’s head in a bowl of water.)
But what may come as a surprise is there are actually many different kinds of contact lenses, and they fall under two main categories: hard and soft. To help you become familiar with the various types of contacts, we’ve made a little crash course. Check it out.
Soft Contact Lenses
These are the most popular lenses for consumers. Soft contact lenses are composed of a type of plastic and water which allow oxygen to reach the eye. They’re comfortable and come in several varieties, many of which are disposable for added convenience. These are some of the different types:
Hard Contact Lenses
The hard contact lenses most commonly used today are called RGP (rigid, gas-permeable lenses). They’re made of silicone or fluoropolymers which allow them to hold their shape. These contacts also permit oxygen to freely flow through the lenses to the cornea. Sometimes, RGP lenses are the preferred choice over soft lenses for correcting astigmatism in the cornea. They’re also helpful if you have allergies or tend to form protein deposits on your contacts.
Bifocal or Multifocal Contact Lenses
If you have trouble with both near and far vision, your optometrist may prescribe bifocals or multifocal lenses. These lenses can help correct myopia (nearsightedness), hyperopia (farsightedness) and presbyopia, which is when your eye loses the ability to focus from far to near as you get older. Bifocal and multifocal lenses are available in both soft and hard lens types.
