Presbyopia glasses in different forms

Some people may not know the exact meaning of presbyopia glasses. In simple words, it refers to prescription eyeglasses for presbyopia correction. It is necessary to discuss some aspects of this bothersome eye condition. Presbyopia is a natural part of aging and individuals over 40 years old will suffer this problem sooner or later. Most eye doctors believe that presbyopia is a natural phenomenon and is independent from other vision problems like nearsightedness and farsightedness. The first and foremost sign of developing presbyopia is a difficulty seeing details up close. At this point, old eyes can not grasp clearly the notes and signs on materials that are just in front of the body. Over time, the old eyes will continue to advance and become more rigid.

Since a majority of the world’s population will suffer presbyopia, finding appropriate solutions become a great and significant task. Until now, major treatments for presbyopic patients include presbyopia glasses, contact lenses and surgeries. The first solution is the commonest because it is the safest and easiest. Eyeglasses for presbyopic correction come in different forms. Reading glasses have a longest history and they are followed by bifocal reading glasses, trifocal reading glasses and progressive reading glasses. This progress in presbyopia eyewear represents the continuous development in lens industry. In detail, reading glasses use single-vision lenses which can only compromise presbyopia and “restore” close vision. Bifocal reading glasses have two focal points and thus can deal with another refractive error. More powerfully, a trifocal lens is capable of managing intermediate vision. Progressive reading glasses are widely recognized as the most advanced form.

Except for various forms of presbyopia glasses, prescription contact lenses in bifocal, trifocal and progressive forms can also correct presbyopia. Contact lenses in different forms are actually made in similar concepts to corresponding eyeglass lenses. And they function also in similar ways. Unlike presbyopic eyewear and contacts, surgeries like LASIK, PRK and CK can help cure presbyopia in a relatively permanent way. During these surgeries, an ophthalmologist will use artificial multifocal lenses to replace the old, improper-functioning natural lenses.
