Can Wearing Contact Lenses Harm You? Modern contacts are made to very high standards.
Millions wear them daily and for years without health problems or discomfort. Still, about 4% of all contact lens users experience some form of health issue at some time. Risks of wearing contact lenses, whilst extremely low, aren't nil. Your chances can be improved by correct use, though.
One overall issue is the indisputable fact that any contact lens will prohibit the quantity of air that gets to the eye. That increases the odds of infection, even if lenses are well sterilised. With the recognition of seven day or perhaps 30-day successive wear lenses, that problem ( whilst tiny ) is bigger than it was during the past. Aside from infection, discomfort and blurred vision can happen when a lens is worn for over some days. That irritation can happen to the eyeball itself, and also to the lens and surrounding tissues. GPC produces itching and redness on the encompassing tissue, the result of protein buildup on the surfaces of the lens. Swelling happens on the inside surface of the eyelids and can produce a sticky discharge too. When this happens, you must abandon use till your eye care pro declares the lenses are safe to wear again. Regular, careful lens care and correct use can reduce the percentages of any re-occurrence. Corneal erosions, whilst unusual, are also far from unknown among contact lens users.
A tiny scratch on the clear tissue over the pupil can occur when little particles of grit get between the lens and the eye, sometimes as a consequence of poor cleaning or handling. But it can happen even to the most careful, as airborne or finger-borne material lands on the skin of the eyeball. Tiny pieces of eyelash, cotton threads, airborne plant material and much more can all wind up in the eye. With a lack of contacts these things are routinely washed away by the tears and eyelid collaborating. In several examples, antibiotics are requested since infection is common under these circumstances.
Pollen and other material can also produce allergic reactions that are occasionally amplified by contact lenses. The eyes become red and irritated and unnecessary ripping can happen, leading to blurred vision and discomfort. Occasionally the reaction is the result of additives in the lens cleaning solution. It occurs more frequently with wearing soft contact lenses. Treatments include removing the lens for a while, changing solutions and using different storage methods. The lenses themselves may cause issues if they change shape. Whilst rare, formerly well-fitting contacts can suffer the effects of temperature and age, causing tears and oxygen to less efficiently make it to the eye. This supposed Tight Lens Condition may cause agony, redness and even swelling of the cornea.
Correction contains remeasuring the eye and fitting new contacts after the eyes have recovered. The cornea itself can change shape, as can the entire eyeball. The change is refined, but with contacts the tolerations are tiny. If corneal warpage ( as it's called ) does happen the result can be discomfort and a rise in the chances of infection. The condition is more common with gas permeable and hard lenses, which are less flexible than soft contacts. If this occurs, healing can take weeks or months, during which time contacts can not be worn. As the eye resumes its ordinary shape, vision can change. More than one glasses prescription could be needed for optimal sight. In rare cases the astigmatism is permanent.
In all cases, following the manufacturer's and your eye care professional's guidance about cleaning, insertion and removal, contact lens care and wear are your best bet to avoiding problems.
