What Are Varifocal Glasses?

Varifocal glasses, also known as varifocals, varifocal lens, PLA, or progressive lenses, have a gradual change in strength from the top of the lens to the bottom with multiple focal points in between. Unlike bifocals, varifocal glasses have no specific area of lens strength, but progressive lens zones.

The way to look through varifocal glasses depends on what you want to look at. If you are looking at the distance, you look through the top of the lens. If you want to look at the close objects, you may need to move your eyes lower to keep the objects in focus. For the best close-up focus, you need to look through the bottom of the lens.

The benefits of varifocal glasses are that they do not need to buy or prepare 2 separate pairs of glasses or need to switch between frames for different vision needs.

However, if you wear the varifocal glasses for the first time, you may come across some problems.
