What are Bifocal Contact Lenses?

About Bifocal Contacts

The objective of bifocal contact lenses is similar to that of bifocal eyeglasses although they work differently. With bifocal contacts there will be no complaining about fine print and no need for age-revealing bifocal eyeglasses.

The bifocal term refers to the purpose of bifocal lenses which is to provide both distance and near vision correction in each lens. Since each lens of bifocal lenses has at least two power in it, bifocal lenses are also called multifocal contacts.

There are many brands of multifocal contact lenses -- signature labels and private labels. These lenses now have come in different styles and colors. They do not only give functional value but also provide aesthetic appeal.

How Do Bifocal Contacts Work?

A bifocal lens works like a bifocal eyeglass lens. Each bifocal lens has two powers: one to correct near vision, and the other to correct distance vision. But the way powers distributed on the lens differentiates how bifocal contacts work.

A concentric, progressive contact lens, for example, works like a progressive eyeglass lens because the powers are finely distributed to different parts of the lens.

Another Option for Multifocal Contact Lenses

Do you find it difficult to choose different powers during, primarily during your early period of adjustment? If you aren't satisfied with multifocal contact lenses chances are monovision can meet your vision needs.

There are monovision contact lenses -- available in less expensive spherical lenses -- that can correct your vision and are easier to fit. In this arrangement one lens corrects distance vision and another lens corrects near vision. Some wearers don't even notice which part of the eye is responsible for distance or near vision correction.

However, others wearers don't like the loss of three dimensions vision that it causes. For them, adjusting to alteration of depth perception aspect in monovision contacts also requires a longer period of adaptation compared to that of bifocal contact lenses.
