The objective of bifocal contact lenses design 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 contact lenses.
How Bifocal Contact Lenses Work
A bifocal lens works like a bifocal eyeglass lens. Each bifocal lens has two powers: one for correcting near vision, and the other for correcting 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.
Multifocal Or Bifocal Contact Lens Manufacturers and Brands
Bifocal contact lens manufacturers are out there producing and marketing popular contact lens brands. Manufacturers like Ciba Vision and CooperVision are two examples of leading multifocal contact lens makers with many lines of contacts for correcting different types of presbyopia problems.
The above manufacturers market their products under many contact lens brands for different target audience. You can find signature labels such as Air Optix Aqua from Ciba Vision and Biofinity Multifocal from CooperVision. But there are also the private labels ones.
These presbyopia contact lenses now come in different styles and colors, which not only give functional value but also aesthetic appeal.
Bifocal Contact Lenses for Astigmatism
If you have astigmatism and want to continue wearing contact lenses at your 40+ you may want to try multifocal toric contacts. Bifocal toric lenses can correct presbyopia and astigmatism. There are some soft toric bifocal brands like Proclear multifocal toric. Also, ask your eye doctor if there are RGP contacts available for this type of prescription.
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.
What You Can Expect from Multifocal and Bifocal Contact Lenses
Fitting multifocal contacts is a complex process. You will need to work together with your eye doctor for a period of trial and error. Also, remember to negotiate the total fitting fees upfront. This is to avoid dispute when you are not satisfied with the results after the fitting services have been rendered.
For the above reasons, make sure that the doctor understands your primary vision goal from the beginning. Also, keep in mind is that the vision clarity of multifocal and bifocal contact lenses are lower than glasses or even spherical contacts. Using the knowledge you can ask the doctor for trying different options until you get an acceptable level of vision clarity.
