Progressive Lenses

Benefits of Progressive Lenses:

With progressive lenses, you won't need to have more than one pair of glasses with you. You don't need to swap between your reading and regular glasses.

Drawbacks of Progressive Lenses:

It takes time to adjust to progressives. You need to train yourself to look out of the lower part of the lens when you're reading, to look straight ahead for distance, and to look somewhere between the two spots for middle distance or computer work.
