There are many different options when you need glasses. Most people start with single vision glasses where they are set for either just distance or just near then transition to glasses for distance and near. The articles below are provided by to aid in understanding the differences between bifocals, trifocals, and progressive addition lenses.


Progressive addition lenses are what most people need when they need bifocals. They have areas specifically for distance, intermediate, and near like trifocals except the areas are blended together and the reading power gets more powerfully progressively as you go from the top to bottom.

Progressive addition lenses or no-line bifocals


Bifocals are used for people who need correction for distance as well as near tasks. The top portion of the lens has the distance prescription and the bottom power is set for reading and close work.



Trifocals are very similar to bifocals except they have a second line in the lens. The area in the middle is used for intermediate or arm's length distance. It allows you to see well in the distance, at the computer distance, and up close.
