Eyecare Glossary

Bifocals are eyeglass lenses that consist of two distinct lens powers in a single lens. They are typically used to correct presbyopia and have a visible line separating the distance prescription in the upper part of the lens from the near prescription in the lower part. Bifocals allow wearers to have clear vision for both distance and near tasks without needing to switch between multiple pairs of glasses. More about Bifocals...
