Redness, Dryness and Swelling
Did you know that the cornea of the eye is one of the few locations on your body that directly "breathes" oxygen from the air? For this reason, your contact lens must be breathable or else you'll experience much discomfort or even damage to your eye. Not all contacts are right for everyone's eyes. Just as people are built differently, so too are eyes. While some eyes react well to contacts, others take awhile to adjust to this foreign object and its related solutions.
Contact lens are a foreign object that somewhat block oxygen from being absorbed through the cornea. A person who finds that contacts dry out their eyes too quickly will prefer soft or flexible disposable contacts. On the upside, these soft contacts are very porous and allow more oxygen to get through. The flip side of this feature is more natural light is able to get through as well. The wearer usually finds that his prescription will be adjusted slightly less strong to accommodate this excessive light. Also, the wearer usually is more sensitive to light and is advised to always wear sunglasses outside.
A blood shot eye is another condition that appears when your eye doesn't get enough oxygen. The easiest ways to overcome a blood shot eye is to not wear your contacts longer than recommended. Since the cornea has no blood vessels, the cornea triggers veins around the eye to pump up and get more oxygen. This response can trigger other conditions as well such as macular degeneration disease and corneal neovascularization.
If you encounter pain and swelling in your eyes while you wear contacts, immediately let your regular physician or optometrist know. These conditions are not natural for the eye and sometimes are caused by not properly caring for your lenses. Routinely cleansing your lenses with solutions is very important to remove natural deposits on the lenses and keep your eyes healthy. Special moisteners are available as drops for contact wearers. Since saliva carries nasty germs, you shouldn't use your saliva to wash off or clean your contact lenses. Another tip to keep your eyes from getting irritated while wearing lens is to always fresh makeup so that it doesn't flake into your eyes and slide between your lens and cornea.
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.
