Bifocal Contact Lenses. See Near, Far, Wherever You Are.
Contact lens wearers who suffer from presbyopia will be thrilled to hear about multifocal and bifocal contact lenses.
Multifocal lenses provide a great boost in reading ability and use a prgressive type of reading add power. Bifocal lenses are usually made of gas permeable materials and look similar to the ben franklin eyeglasses (only much smaller). They have a distinct line between the distance and near portion of the lens. Bifocal lenses take precision and expertise to fit properly.
Most modern designs of gas permeable multifocal contact lenses will incorporate a type of combination between multi and bi focal optics, providing the wearer with the best possible vision correction.
Multifocal contact lenses are manufactured in both soft and gas permeable designs. And more recently, a combination style of multifocal has come to the market. The Synergeyes Multifocal Hybrid Contact Lenses provide the comfort of a soft lens with the optics of a gas permeable contact.
Multifocal contact lenses usually consist of an aspheric surface that gradually increases or decreases add power away from the optic center. A major key to success in being fit with multifocal or bifocal lenses is to have realistic expectations. The more add power a lens has for near vision, the more potential there is for distortion in the distance. Most multifocal contact lens fittings are designed to be optimized for vision with two eyes together.
Another reality is that multifocals will not always eliminate the need for reading glasses. What they will do is drastically reduce your dependency on them and the strength needed. For emerging presbyopes (early 40's), multifocal contacts can delay the need for reading glasses a few more years. If you are interested in being fit with multifocal lenses, contact your eye care practitioner today for an appointment.
