How Do Contact Lenses Work?

How do contact lenses work, you ask? It may as well be a mystery to some, but today, it'll no longer be a mystery for you. Well, contacts work the same way glasses do, of course! However, contacts lens material is made differently than the standard issue glasses material. The technology allows for a full spectrum of vision to be seen through a much smaller and thinner piece of plastic. Thus, contacts can be worn safely on the eyes without adding much in weight or depth, like glasses can add.

Contact lenses work simply the same way glasses do, except they are more internally oriented than their glasses counterparts. They just are made smaller, and as such, have condensed the corrected vision down with it to allow for contact to be made directly with the cornea. Contacts are just a portable version of glasses, if you will, and as such, they correct vision in the same way glasses would if worn regularly.

Contact lenses are worn on the cornea so that their use can be targeted to the retina, where you do most of your seeing. As you blink, the contact lens is washed with naturally produced tears that keeps it lubricated and overall keeps your eye in a comfortable condition. When you open your eye from that blink, you are able to see clearly as your vision is focused normally, even with the contact over the cornea, because your eyes will automatically adjust to the "foreign object" being placed on it.
