Recently, a microblogging site about “wearing contacts that cause eye stones” has been hotly debated by netizens, and the picture of an eyelid covered with dense white dots is even more frightening. Many people are confused: what are eye stones? The actual fact is that you will be able to wear contact lenses for many years and you will have eye stones? Eye stones are not “real stones”. Eye stones are not the same as kidney stones or liver and gallstones, but are actually just a minor eye problem. Generally speaking, eye stones are only minor eye problems with little or no calcium deposits and are not real stones, so in most cases they do not require surgery to remove. When the stone is just a small particle buried under the conjunctiva and not protruding beyond the surface of the conjunctiva, people do not feel the stone and can ignore it for a while. When it emerges, it can cause irritation to the eyelid and even abrasion to the cornea, causing a foreign body and stinging pain in the eye. Some people grow new eye stones soon after treatment. Eye stones are often caused by inflammation of the eye, and the inflammation is not eliminated, and only the stones are removed symptomatically, the source of the disease is not broken, so it may recur. It is understood that patients with chronic keratitis and the elderly are at a high risk of eye stones, such as the elderly with the age of the conjunctival epithelial degeneration, creating an opportunity for the occurrence of eye stones. In addition, trachoma, dry eye disease and other common modern eye diseases may also lead to eye stones. As for the claim by netizens that wearing contact lenses causes eye stones, doctors believe that improper stimulation of the eyelids may also lead to eye stones, if no attention is paid to hygiene during the wearing of contact lenses. Most eye stones are caused by inflammation, and the key to preventing eye stones is to prevent eye inflammation. Doctors recommend that you seek medical attention to eliminate inflammation in the event of eye discomfort. It is also important to develop healthy eye habits, not to rub your eyes and to keep them moist. Contact lens wearers should pay attention to lens disinfection and maintenance, regular eye examinations, if not suitable for wearing contact lenses, do not try reluctantly. It is best to wear protective eyewear in a sandy environment to avoid sand blowing directly into the eyes. Although eye stones are only small lesions of the conjunctiva, they are a “red flag” to alert you to the health of the conjunctiva. In addition, if eye stones grow again and again, removing them frequently can harm your eyes, even though there is no risk of blindness.
