In people who constantly wear contact lenses, Over time, vision may deteriorate significantly. This was recently reported by employees of the Center for Disease Control and Prevention, noting that the use of contact lenses leads to vision problems and even to development blindness.
The fact is that people who prefer lenses often parasitize organisms that provoke an infection that is very dangerous for the eyes. Doctors working in the center reported one case: a woman, as a result of wearing them, was blinded in one eye. After the doctors conducted a full examination, it was determined that a microscopic parasite, called Acanthamoeba. As a result, the woman fell ill acanthambic keratitis. Because of this infection, the eye is blind.
Doctors explain that such a microorganism can live in a liquid where contact lenses are stored, from which it penetrates the eyes. This parasite damages the cornea, which leads to pain, redness, and visual impairment. It seems to a person that something constantly creeps in his eye.
A parasite can be detected by taking a scraping from the cornea, and this can also be done using a microscope. It is important to detect the pest in time and start treatment, otherwise the infected patient will suffer from severe pain and may even lose his sight after some time.
Therefore, Australian scientists urge contact lens wearers to carefully adhere to all hygiene rules, and also visit a doctor if there is some discomfort. Also, to maintain vision, it is very important not to fall asleep without removing the lenses. After all, during sleep, they will not receive enough oxygen. The likelihood of infection also increases. If the eyes are closed, bacteria entering the cornea are not washed off.

These are special models that are thrown away after socks. But since few can afford such squandering, it is important, at least, not to wear these devices after their expiration date has expired. It is best to purchase not one, but several pairs of lenses, so that, if necessary, immediately replace them. And, before you start wearing lenses, you must definitely familiarize yourself with the rules for their use.
