Glasses or contact lenses are the standard treatment for presbyopia. These lenses compensate for the hardness of the lens in the eye, which is responsible for presbyopia. Surgery is also a possibility. Surgery reshapes the cornea to compensate for the lens's inability to create proper focus.

Laura Fine, Ophthalmology, answeredThe most common remedy for presbyopia (a loss in the eye's focusing ability that occurs with age) is optical correction -- reading glasses. If you already wear corrective lenses, you might consider bifocals, trifocals, or progressive lenses, which combine several levels of adjustment to correct both distance and close-up vision problems. Some people use two pairs of glasses -- one for distance and one for close work. Many drugstores and supermarkets carry magnifying reading glasses that may help. You should consult your ophthalmologist about an appropriate strength before purchasing a pair, and you should never buy reading glasses in lieu of having an eye examination.
You can also get prescription contact lenses that correct the vision in one eye for reading and the other for distance -- a technique called monovision. Multifocal contact lenses (combining several levels of adjustment, as found in bifocal, trifocal, or progressive lenses) are also available. Whichever type of lens you choose, you may need frequent changes in prescription, because presbyopia becomes progressively worse until about age 60 to 65, when it stabilizes.
Another possible option is a novel type of eyewear called Trufocals, which are adjustable focusing eyeglasses. Each lens features a flexible lens with a transparent membrane attached to a rigid surface, with a pocket of clear fluid in between. If the wearer moves a tiny slider on the bridge of the glasses, the fluid shifts and alters the shape of the flexible lens, thereby changing the visual correction. That allows the wearer to focus at a range of distances, from near to far, without zones or lines.
