Bifocal Contact Lenses

Bifocal Contact Lenses are used when we are suffering with presbyopia, which is the lack of focusing on things in close range. The cause for this is the lens in our eyes becoming less and less flexible as we grow older. At some point in our lives, most of us will need some type of corrective lenses, such as contact lenses or glasses and possibly even bifocals, as this condition gets worse.

Until Recently, those who wore bifocals had very limited options when they chose their corrective lenses. Glasses containing bifocal lenses were just the only option available for years ago. Over the years, no-line lenses were created, and glasses became a bit more attractive. For bifocal correction lenses, this was a very definitive time, as they appears to be a lot better than they ever did in the past – getting rid of the massive and unattractive appearance, they were well known for.

Now days, on the market, you can find many different types of bifocal contact lenses. Since they give those who wear bifocal glasses a very attractive alternative to wearing bulky glasses, they are gaining in popularity. They are very reasonably priced as well - which makes them a more popular choice in the world of corrective lenses.

What many may not realize is the fact that by means of the way they work, bifocal contacts are very similar to glass lenses. With glass lenses, each separate lens provides a range of focus adjustments, one for distance, and another for being close up on something. With bifocal contact lenses, both of the adjustments are included. In order to produce different types of bifocal contact lenses, there are different manufacturers, meaning that it may take you a bit of research and experimenting to find which type works the most excellent for you.

Types of Bifocal Contact Lenses

1. Concentric Bifocal Contact Lenses
2. Aspheric Bifocal Contact Lenses
3. Translating Bifocal Contact Lenses

Concentric Bifocal Contact Lenses

Some lenses however, are made with a unique design, known as concentric. Analogous to concentric circles, there are two adjustments - one in the middle the other around the outside. With a sharp line in between them, these two adjustments in the contact lens are very distinct. Although they may sound hard to use, most people find that they are easy use with a little bit of practice.

Aspheric Bifocal Contact Lenses

One type of bifocal lens is the aspheric lens, which have a more steady change of focus. In the central area of the pupil, both powers are present and similar to the concentric lens, your eye will immediately adjust to these lenses and decide on the focus that is best to use.

Translating Bifocal Contact Lenses

The third and possibly best lens for bifocal use is the translating lens. Similar to bifocal glass lenses, the near correction is found at the bottom of the lens, and the distance correction is found at the top. When they are in the eye, these lenses aren’t able to shift, as they are made not able to shift around normally. No matter what you do, these contacts won’t move around. For this reason, this can be great for older individuals.

Prior to opting for bifocal contact lenses, you should always ask your optician what he thinks is best for your eyes. If you meet the exact criteria, chances are you’ll be prescribed bifocal contact lenses. You may find these contacts to be the perfect alternative if you wear bifocal glasses. For those who like plenty of choices, you can get bifocal lenses in extended wear, daily disposable, or even conventional. Bifocal contact lenses are the ideal substitute for anyone who requires bifocal correction lenses with a lot to choose from and a lot to offer.
