What is the difference between bifocal and varifocal glasses?
Varifocal and Bifocal lenses usually have distance and reading powers to correct presbyopia. Varifocal lenses allow you to see near and far objects ( and all distances in-between)using just one pair of glasses. Unlike bifocals, there’s no visible line on the surface of the lens (Bifocal lenses contain only two prescription powers in one lens). With Varifocals it doesn’t matter whether you’re reading a book, watching TV or driving, as you’ll you only ever need one pair of glasses, making them convenient for people who would otherwise have to carry two pairs of glasses.
