SINGLE VISION
These lenses have the same focal power throughout and can be used to correct nearsightedness, farsightedness, astigmatism, or a combination of each.
Single Vision start at $50 per pair
BIFOCAL
These lenses have two focal powers: the upper part is normally used to correct distance vision and the lower part is used to correct near-vision tasks,such as reading.
Bifocals start at $75 per pair
PROGRESSIVE
These lenses are often referred to as No-Line Bifocals. Progressives have no clear dividing lines as the focal powers change from distance to near vision. They give the wearer multiple focal points from the top of the lens (distance) to the bottom (near) and every point in between. They have become popular in recent years because other people cannot tell that you are wearing bifocals.
Progressives start at $160
