What does it mean if you wear bifocals?

Bifocals are two lenses in one. One part, or segment (usually the bottom), is made to adjust the eye for close focus, and the other (top) has a different strength for distant focus. The key to wearing bifocals is to learn to automatically look through the proper part of the glass.

How do you tell if your bifocals are correct?

Some bifocal glasses have a line across the middle that divide the two corrections. Trifocals correct your vision so you can see close up, middle distance, or far away. They may also may have lines or come in a progressive lens.
