Bifocal Contact Lenses:
The Lens Type For Visual Freedom

If you suffer from an eye condition called presbyopia you will need special eye correction eyeglasses known as bi-focals. For many years people who needed bi-focal correction were limited to only frames, but over the past recent decade, bifocal contact lenses have become available; allowing people to look and feel their best! Bifocal contact lenses are now available for disposable and conventional use, and can be purchased as both rigid gas permeable and soft.

Presbyopia is a condition that is primarily suffered by older persons, and usually happens to people once they reach their 40's. Your eyes age with your body, so you may find that you are having difficulty reading, and you hold your reading material at a distant in order to see the print. Other symptoms of that you may experience include: strain, headaches and blurred vision.

Bifocal contact lenses work in the same respect as the glasses. Each lens is designed with two features that correct both near-sighted and far-sighted vision. They can be split across the middle exactly like bi-glasses - the top being made for distance and the bottom for nearness. You can also obtain types that are like progressive eye-glasses. These have different powers of perspective combined over the lense; this allows your eye to learn how to focus and distinguish vision elements on their own.

There are three basic designs: Translating, Concentric and Aspheric. Each of these provides a different way to correct your vision. Translating types are made with the visual correction that is split in the middle. The near-sightedness correction is on the bottom half, and the edge at the bottom is created flat and not round like the rest of it. This is so that when you blink, it will not shift and disrupt your vision. Concentric ones are designed so that the near vision correction is located in the middle, and the distance correction is on the outer area of the contact. The final kind is Aspheric. These are designed so that the correction for distance and nearsightedness is located near the pupil.

This form of lens is a tremendous invention and designed by many companies, such as Bausch and Lomb and Acuvue. Discuss the best choices available to you with your ophthalmologist and find out his or her recommendations.
