Boothe Laser Center Discusses Unpleasant Facts About Contact Lenses
Contact lenses are considered by many perfect alternative to eyeglasses. They make it possible to avoid common “foureyes” issues such as a visual field reduction, optical distortions, eyeglasses lens breathing, and giving up some sports. Not to mention the pressure on the nose and ears as well as appearance issues.
However, recently ophthalmologists often notice negative consequences connected with improper or long-term use of contact lens.
Colored contact lenses
The U.S. Food and Drug Administration (FDA) recently announced a public warning regarding the use of colored contact lenses that became very popular among people all over the United States, especially teenagers and young adults. For some reason, many people feel that this type of contacts are intended only for changing their eyes’ color rather than for vision correction, and they can buy and wear them without a proper ophthalmology consultation (as well as without sunglasses). Meanwhile, according to FDA data, some of these contact lenses, which are sold for less than $50 on beaches, in markets and on the Internet, lead to corneal inflammation. Dr. Boothe added that in the worst cases the eye infection and other complications caused by the use of such contacts may lead to blindness. Other complaints made by wearers include suffering from conjunctivitis, corneal edema, allergic reactions and deterioration of contrast sensitivity.
Contact lens can scratch your eye
Dr. Boothe says that wearing of soft contact lenses may lead to the damage of outer eye layers even if you properly take care of them. Researchers of Ohio University have found that more than half of contact lens wearers experience corneal damage of at least in one eye. One in every thirteen “scratches” represents a danger to vision.
During research, experts of twenty leading clinics examined five hundred people who was wearing contacts lenses eight hours a day, five days a week. To detect superficial damages a special fluorescent-containing probe was used. The fact is that fluorescent lingers on the damaged areas of epithelium and can be easily discovered with special examination light.
The coloration of epithelium, which was indicative of corneal erosion, was detected in almost fifty six percent of examined lens wearers, at least in one eye. Eight percent of examined people were found with moderate to severe corneal damages. According to the researchers, this can lead to infection as well as to formation of sores and scars. Scientists revealed differences in frequency of erosion formations depending on frequency of both contact lens replacement and thoroughness of care. Also, the dependence on contact lens optical power was revealed: people with farsightedness and moderate to severe nearsightedness suffered from corneal damages more often than others.
