Multifocal contact lens offers eyeglass wearers a new alternative.

Sufferers from impaired vision are no longer restricted to only being able to have it corrected with eyeglasses. Contact lenses are available in a variety of forms to suit most needs and lifestyles, from soft or hard gas permeable ones to convenient disposables, with the multifocal contact lens providing correction of bifocal problems.

The first development of the multifocal lens concept was the bifocal variant, which featured two parts to each lens, the upper part to deal with long distance vision and a lower part to deal with close-up vision . The multifocal lens was the logical extension to that concept. It is prescribed most commonly for presbyopia, the condition that is caused by the loss of elasticity in the muscles controlling the focusing function.

Whereas the bifocal has two distinct segments to the lens, which correct to fixed focal lengths, the multifocal lens corrects progressively through a range of focal lengths. Usually, it is constructed with a small circular or slightly elliptical central core with outer concentric sections. The inner part corrects close-up vision, the outer part correcting longer distances.

This is a modern hi-tech product manufactured to the highest precision standards. The lens is safe to wear for anybody with healthy eyes, and the choice of versions makes it available to people in all walks of life and lifestyles.

The latest version of the multifocal lens is able to mimic the reactions of a perfect eye with no perception to the user. It reacts not only to changes in ambient lighting conditions but also to subtle variations in pupil size. This is a huge improvement over the bifocal lenses of the past.
