Imaginary harm
There are many misconceptions related tothe harmfulness of contact lenses. Some people are sure that the contact lens can roll over the eyeball, others insist that the use of lenses can lead to poor eyesight. In most cases, all doubts about the use of contact lenses disappear after the first conversation with the oculist.Real harm
In some cases, contact lenses,really, can do much harm. This mainly concerns the danger of microbial keratitis development. If a person does not follow the recommendations on the use and storage of contact lenses, they can become a source of pathogens and lead to the formation of keratitis. Keratitis is an inflammatory disease of the cornea, which is characterized by cutting and irritation in the eyes, abundant lacrimation and other unpleasant symptoms. Sometimes keratitis can lead to a noticeable impairment of vision. A lot about infectious keratitis was started in 2006, when several tens of people in the United States and Asia were affected by the disease. All of them wore contact lenses and received a severe form of fungal keratitis. A year later a new scandal broke out - in a lens solution made in the United States, a causative agent of amoebic keratitis was found. According to studies, up to 125 cases of infection with bacterial keratitis occur for every 10,000 people using silicone-hydrogel lenses. People who wear lenses continuously and for a long time fall into the risk group, they prefer not to change them too often and have different backgrounds - eye injuries, weakened health, etc. If you are afraid of keratitis, follow the simple rule: change lenses more often. This reduces the likelihood of infection by harmful microorganisms. Ideal option - the use of one-day lenses. Do not forget to watch your health, at the first unpleasant sensations in the eyes, contact the oculist.
