The cornea of the eye is one of the few "breathing" organs of the body. Hence, contact lens must be able to breathe in order for you not to experience the discomforts that many people encounter upon wearing contacts. Some contacts are better for some people's eyes since some eyes are able to absorb oxygen better. Unfortunately, not all eyes react positively to a foreign object like contact lens. For some people, it takes some time for your eyes to adjust to direct contact with lenses.
Since contacts lie directly on the cornea, some oxygen is blocked from being absorbed. Some people who find that their eyes dry very quickly prefer wearing more porous contacts like soft or flexible disposable contacts. Since these contacts allow more oxygen to filter through the lenses, the eye doesn't get as dry. However, these contacts also allow more light to filter through as well, so the wearer's prescription must be adjusted for this. Most soft contact wearers are highly advised to wear sunglasses outside to reduce sensitivity to sunlight.
When the eye doesn~t get enough oxygen, it tends to look blood shot. While the cornea is one of the few places on your body - outside the hair and nails - that have no blood vessels, the eye will start to react to this loss by pumping up the veins around the cornea, such as in the retina. Extended contact wear and wearing your contacts beyond their recommended period of time exasperate red eye. If red eye exists long enough, it can trigger other conditions, such as corneal neovascularization, and diseases, such as macular degeneration.
Pain and swelling are not natural for the eye. If you encounter this as result of wearing contacts, immediately inform your optometrist or regular physician. Many times, these conditions are caused by improper care of your lens. Ritualistic cleaning with lens solutions cut down many symptoms. The cleaning removes deposits that naturally build on the lenses and also moisten your eyes. Using saliva as a cleaner is never advised as saliva can carry infectious germs. Also, fresh makeup prevents pieces from falling into your eye and sliding under your lens.
So many people enjoy wearing contacts and maintain healthy eyes. Statistically, two out of three wearers are women, over 30 million Americans wear contacts, and eight out of ten wear their contacts on a daily basis. The main reason people prefer wearing contacts over wearing glasses is people feel they look better. Furthermore, people who properly care for their lenses and properly moisten and rest their eyes encounter far less symptoms associated with wearing contacts.Contact Petra Thurel
