Could wearing contact lenses actually damage your eyes?

Millions of people the world over wear them daily and for years without health issues or maybe discomfort.

Still, about 4% of all contact lenses users experience some form of health issue at some time. Hazards of wearing contact lenses, whilst terribly low, are now not nil. Your percentages can be improved by correct use, though. One overall issue is the undeniable fact that any contact lens will prohibit the amount of air that gets to the eye. With the recognition of seven day or perhaps 30-day successive wear lenses, that problem ( whilst little ) is bigger than it was in the past.

Except for 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 need to can use until your eye care pro declares the lenses are safe to wear again. Regular, careful lens care and correct use can cut back the chances of any re-occurrence.

 

Corneal erosions, while rare, are also far from unknown among contact lens users. A little scratch on the clear tissue over the pupil can occur when tiny 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. Little 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 usually washed away by the tears and eyelid collaborating. In a lot of examples, antibiotics are requested since infection is common under these circumstances.

Pollen and other material can also produce allergic reactions that are often amplified by contact lenses. The eyes become red and irritated and over the top ripping can happen, leading to blurred vision and discomfort. Often the reaction is the result of additives in the lens cleaning solution. It occurs more frequently with soft contact lenses. Treatments include removing the lens for a while, changing solutions and using different storage techniques. The lenses themselves could cause issues if they change shape. Whilst rare, formerly well-fitting contact lenses can notice 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 pain, 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 delicate, but with contact lenses the tolerations are little.

If corneal warpage ( as it's called ) does occur the result can be discomfort and a rise in the chances of infection. The condition is commoner with gas permeable and hard lenses, which are less flexible than soft contact lenses. If this occurs, healing can take weeks or months, during which time contact lenses cannot be worn. As the eye resumes its ordinary shape, vision can change. In rare cases the astigmatism is permanent. In all cases, following the maker's and your eye care pro's guidance about cleaning, insertion and removal, contact lenses care and wear are your best shot to avoiding issues.
