An English-language study published last year in the journal Eye cited corneal opacities as the fifth leading cause of blindness in the world, with infectious keratitis or corneal ulcers (infection caused by viruses, bacteria, fungi, or parasites) as the leading cause.
“Ulcers, when deep, cause a scar at the front of the eye, impairing vision. Severe cases that do not respond to treatment can develop into a perforation of the eye,” explains Tatiana.
A North Carolina study found that the risk of developing corneal ulcers is about nine times more common in patients who wear contact lenses. This is explained by the fact that contact lenses reduce the exchange of tears during blinking and facilitate the accumulation and adherence of microbes to the cornea.
How do you wear contact lenses?
“It is important that contact lenses be fitted and prescribed by an ophthalmologist. The grade is not always the same as the glasses. In addition, a loose or narrow lens can cause discomfort, corneal infections, and the growth of abnormal vessels in the cornea.
The time for wearing and replacing lenses, as well as the use of cleaning solutions and methods for cleaning and storing lenses, must be respected. Other recommendations on correct use are: do not sleep in your eyes, do not take a shower and do not enter the sea, river or pool with lenses; Use preservative-free moisturizing eye drops and replacement lenses with glasses.
Tanaka concludes, “If you experience discomfort, pain, redness of the eyes, or blurred vision, discontinue use and seek professional care.”
