Bifocal contact lenses for near and far now all in the same lens

Were you aware that there is now an alternative to reading glasses or bifocals for those who have presbyopia? (An age related issue involving hardening of the eye that prevents focusing on close objects). There is now an alternative for older people who have this condition: bifocal contact lenses.

• Getting used to bifocal contact lenses takes some time

Bifocal contact lenses can help with vision both near and far away as well as helping to solve problems with astigmatism. As with traditional glasses, some bifocal contact lenses have most of the surface area designed for distance viewing while a small portion is for near sighted vision. Another model for the bifocal contact lenses involves concentric rings. While this may seem strange, it can work because of the way the brain can interpret the signals from the brain and adjust accordingly. In a few days, and with some individuals in a few hours your brain will adjust. Going back to ordinary glasses goes even faster.

Another variation on this theme of bifocal contact lenses is that of monovision. People wear one contact lens with a distance prescription in one eye and one with a near vision prescription in the other eye. Once again the brain is vital in interpreting and choosing which eye to use at different points, and it takes some time to get used to. However, many people prefer bifocal contact lenses to this option.

• Bifocal contact lenses to choose from

Bifocal contact lenses come in different varieties. There are both soft and hard lenses available. However, in the case of bifocal contact lenses, many people find that hard lenses are a better choice. Gas permeable lenses are better at keeping their shape, which can be especially helpful with bifocal contact lenses since it avoids the eyes straining to refocus.

Since bifocal contact lenses are typically worn by older people, gas permeable lenses may also be preferable because they are less likely to absorb the water from your eyes as soft lenses will. Older people sometimes suffer from dry eye syndrome, which will not be irritated by their bifocal contact lenses if they are gas permeable.
