Some people who require reading glasses prefer half glasses. When using half glasses, you look through the glasses to read, and over the glasses to see at a distance. These are for people who need both near and far correction. One area of the lens corrects for vision at a distance, the other for near vision. PALs are cosmetically pleasing and offer visual correction that's superior to traditional lined bifocal and trifocal lenses.
Many people prefer contact lenses to eyeglasses because they provide a more natural look.
You have three options for wearing contact lenses to correct presbyopia. Multifocal contact lenses. Like bifocal eyeglasses, these specialty contact lenses utilize two separate optical areas one for correcting vision at a distance and the other for near vision. One eye is fitted with a contact lens to see well at a distance while the other eye is fitted with a lens to provide sharp, close-up vision. Although this may seem odd at first, the brain is very adept at reconciling the difference into consistent, clear vision, both near and far.
