What Are The Dangers Of Contact Lenses To The Eyes?
First, the eye resistance is decreased
Contact lenses will prevent the cornea from reaching the air, and the eye will suffer from a condition similar to "altitude sickness" in the human body due to lack of oxygen.
Two, lead to visual fatigue, dry eye disease
Wear contact lenses for a long time, easy to produce visual fatigue, and even cause dry eyes. Causes eye itching, foreign body sensation, eye excrement, dry feeling, eyes burning and blurred vision.
Three, cause eyeball allergy
Contact lenses absorb proteins, lipids, collagen and so on in tears, so that they deposit on the surface of the lens, breeding bacteria, corneal edema, corneal neovascular reaction and allergic reaction and so on.
Four, wear cornea, can not accept correction
Contact lenses wear on the cornea, which can lead to epithelial detachment or perforation of the cornea. Some contact lenses do not conform to corneal convexity, irregular wear of the cornea, causing corneal ulcers, resulting in irreversible vision loss, even after treatment will leave white spots on the cornea.
Five, cause eye paralysis
Contact lenses attached to the eyeball for a long time, will paralyze nerve endings, resulting in loss of corneal perception. Many patients develop ulcerative keratitis without noticing it.
Six, corneal aging is accelerated
If you start wearing soft contact lenses at the age of 20, ten years later, the density of endothelial cells in the cornea is equivalent to that of a 60-year-old and will not be able to withstand any eye surgery, even if cataracts develop in old age.
Seven, the degree of myopia deepens, affecting the image
Contact lenses are difficult to obtain a diopter very consistent with myopia, resulting in the degree of deepening year by year, more than 60 degrees of high myopia most eyeball bulging, dull eyes, affecting the image.
