One way it has been found, is to reduce the water content of the lens. Some people have reacted to the new hydro-gel contact lenses. Contemporary silicon hydrogel lenses are only about 30% water - which is much less than the 50% to 60% of traditional lenses, and 70% of soft contact lenses. Moreover, is the new polymers are used in contact lenses, keep the lens mushy.
Most of the high water content lensesdehydrate rapidly and rely on the eyes tear film to replenish the lost water. For someone that already has dry eyes, this creates a very uncomfortable contact lens environment. Contact lens related dry eye can be very noticeable at the end of the day or during extended computer use.
Soft lenses have a high water content which makes them satisfied primarily and they retain that high water content in most environments. For a person wearing soft contact lens, This means do not hold that absorb so many tears as other lenses in a moist condition to leave. Whether at the computer, the theater or the beach, stay soft contact lenses for dry eyes comfortable.
Contact Lenses Dry Eyes:
Dry eye is a common disease of the inadequacy of the tears in his eyes, or tear caused by undue disappearance. Dry eyes are a number of causes, such as drugs, infections, allergies linkedResponses and contact lens use. Dry eyes often cause contact lens bigotry. A normal person suffers from mild dry eyes may not feel any discomfort until they wear contact lenses, and a growing unease with the hours spent in front of the computer.
Some doctors recommend switching to gas permeable (RGP) contact lenses for dry eye syndrome. RGP contact lenses are made of polymeric materials and contain nono water. This is different than soft lenses evaporates, and so no surface water.
A very important advantage of RGP contact lenses is that they do not clump oxygen flow to the cornea, as they are gas permeable. This is for the eyes as a lack of oxygen can lead to very serious problems, including inflammation of the cornea. Another plus point is that they contain no moisture, they do not dry out. Consequently, they can for the perfectwork under conditions where there is a chance for dry eye syndrome.
