Bifocal Contact Lenses and Presbyopia Information
|Presbyopia comes from the Greek word "presbys" meaning older man or elder with the latin root, opia, meaning eye. It is a condition, normally noticed around 40 years of age, when the eye begins to lose focus at all distances. Eye strain, headaches, and blurry vision can all accompany the onset of presbyopia.
Similar to bifocals and other eyeglasses, bifocal contact lenses were developed to correct vision issues related to the onset of presbyopia. Bifocal lenses come in both soft and hard (RGP) material with disposable versions available for greater convenience.
Bifocal contacts are sometimes referred to as multifocal contact lenses but there is a difference. Multifocal contact lenses can include a range of powers to correct many different vision issues while bifocals have two powers to correct a near and farsightedness problem.
There are a wide range of bifocal and multifocal contact lenses on the market. The Acuvue Oasys for Presbyopia is rapidly gaining in popularity while mainstays like the Soflens Multifocal and Purevision Multifocal continue to be highly prescribed lenses. Proclear Multifocal and Proclear Multifocal Toric are both quickly become a popular prescription in the bifocal market as well.
