In a nutshell, there are four types of lenses used to correct vision: Single vision, Bifocal, Trifocal, and Progressive
- Single vision – As the name indicates, a single vision lens has the same focal power (or magnification) from top to bottom and can be used for nearsightedness, farsightedness, as well as for correcting astigmatism. Single vision lenses are the most common lenses used and, for most first time glass wearers, the first lenses prescribed. While you can purchase inexpensive ready-made single vision readers in most drug stores, they will not correct for astigmatism or in the case where your eyes have different corrective needs, i.e. one eye is a +1.50 and the other is a +2.00. Using readers, in that case, can cause an additional eye strain problems.
- Bifocal – A bifocal lens has two parts: the separate, very distinct lower portion designed for reading or close-up work and the upper portion containing a prescription for distance or even with no correction at all. Using bifocals allows a person to leave their glasses on at all times while retaining the ability to see at various distances.
