Bifocal Glasses Glasses USA : Types, Brands & Tips for Buying<\/span><\/h2>\n

Bifocals are eyeglasses with two distinct optical powers. Bifocals are commonly prescribed to people with presbyopia who also require a correction for myopia, hyperopia, and\/or astigmatism.<\/p>\n

Original bifocals were designed with the most convex lenses (for close viewing) in the lower half of the frame and the least convex lenses on the upper. Up until the beginning of the 20th century two separate lenses were cut in half and combined in the rim of the frame. The mounting of two half lenses into a single frame led to a number of early complications and rendered such spectacles quite fragile.<\/p>\n

A method for fusing the sections of the lenses together was developed by Louis de Wecker at the end of the 19th century and patented by John L. Borsch Jr. in 1908. Today most bifocals are created by molding a reading segment into a primary lens and are available with the reading segments in a variety of shapes and sizes.<\/p>\n
