Contact lenses are small plastic discs that are placed into the eye to correct vision problems. They are a more convenient alternative to glasses.

One of the benefits of contacts over glasses is that they are usually invisible and nobody will know you are wearing them. Contact lenses have improved a lot over the last thirty years and most people don't even know they're wearing them.

Contacts may also be worn for fun when people want to change their eye color.
