RGP bifocal contact lenses as a solution for Presbyopia

There are many products today for those that suffer with vision problems. One type of vision problem is known as presbyopia. This is an age related problem involving the hardening of they eye, which prevents people from focusing their eyes on close objects. One solution to this is rigid gas permeable bifocal contact lenses (RGP bifocal contact lenses for short.)

Traditionally those suffering from presbyopia had to turn to either reading glasses or bifocal glasses. Today, however, RGP bifocal contact lenses can provide wearers with all new alternatives.

• RGP bifocal contact lenses with near-, far- or bifocal powers

RGP bifocal contact lenses help solve the problems of presbyopia by allowing people to focus on objects that are both nearby and far away. RGP bifocal contact lenses can utilize different patterns, but many have sections just like the more traditional glasses, where once section of the lens is used for seeing objects nearby and the rest of the lens is used for objects far away.

Other models for RGP bifocal contact lenses involve concentric rings or non-traditional designs. This design works off the same principle as monovision, in that it expects the eye to adjust to almost contradictory signals. With monovision, wearers have a different prescription in each eye, one for nearsightedness and one for farsightedness. Similarly, RGP bifocal contact lenses that use concentric circles provide the brain with two different images and expect it to adjust and pick the best available image. Just like bifocal glasses these RGP bifocals take some time getting used to.

• The advantages to RGP bifocal contact lenses

There are many advantages to RGP bifocal contact lenses. Although bifocal lenses are available in a soft lens design, many people prefer the RGP bifocal contact lenses. Particularly for the elderly, they help avoid the problems of dry eye syndrome, which is common with soft lenses. RGP bifocal contact lenses also avoid the problems of swimming vision as the wearer tries to readjust their eyesight after blinking. Eyes do not have to strain as much to refocus with RGP bifocal contact lenses.

RGP bifocal contact lenses also provide all the traditional advantages of contacts such as not dealing with glasses that fog up or get covered with rain drops every time there is an afternoon shower. RGP bifocal contact lenses can provide a wonderful alternative for those suffering from presbyopia.
