Bifocal, Multifocal, Progressive & Reading Eyeglasses

Reading glasses can be worn when doing close work; distant objects become blurry however, when viewed through reading glasses. Consequently, some people choose bifocal or multifocal lenses which offer good distance vision through the top and clear reading vision through the bottom (multifocals also give good intermediate vision). People who have good distance vision without glasses may use half glasses to correct presbyopia. Progressive lenses or no line bifocals that allow continuous correction from distance, to intermediate, to reading vision are also a popular choice.
