Bifocal Contact Lens

Bifocal Contact Lenses are Helpful in Correcting Vision in Middle Age!

The term 'Bifocal' refers to two points of focus utilizing two eye powers in one lens. The bifocal contact lenses are being used since 1999 by patients suffering from presbyopia-- a vision disorder characterized by an inability to read fine prints, like reading a book or newspaper. This condition is a common occurrence in middle age, around the age of forty. It is a progressive condition that worsens with increasing age.

Bifocal contact lenses use the same mechanism of working like bifocal glasses. These bifocal contact lenses utilize two eye powers in one lens. One part corrects distance vision and the other rectifies near vision. They are available in soft and rigid gas permeable varieties. However, the rigid gas ones are more common than the soft ones. These contacts can either be disposable or be extended wear.

The disposable bifocals can be daily, weekly, fortnightly or monthly disposable. The standard bifocals are extended wear lenses that may be used for about a year.

The bifocal contacts are available in different designs- concentric, aspheric and translating. Concentric design utilizes the center of the lens for one power and the outside one for the other power. Regressive concentric contacts have near and far vision prescriptions reversed.

Aspheric lens changes the power from the center to the edge of the lens helping to rectify intermediate distances. Aspheric and concentric designs make a transition from far vision to near vision. Translating design rectifies the near vision at the bottom and the distance vision at the top.

Usually bifocal contact lenses are offered for free trails. It may take some time to get accustomed to bifocal contact lenses. These are special order items made as per individual specifications. Bifocal contact lenses require utmost care to keep them away from infection. A proper cleaning and disinfecting routine is essential to maintain good ocular health.

One must purchase only those bifocal lenses that are the best for one’s vision needs. This process may involve visiting an experienced ophthalmologist or optometrist. A skilled eye care professional can help to identify the most suitable contact lens as per individual requirements. He/she can also offer valuable advice about caring for one’s contacts and recommend an apt contact lens brand, after a thorough assessment of the person’s vision needs.

Any advice from the eye specialist would go a long way in keeping eyes healthy and problem free and help to enhance longevity of the bifocal contacts.
