隐形眼镜（Contact lenses） My myopia and astigmatism, we are wearing frame glasses, want to change the invisible, but friends said that the contact lenses are very eyes, just to take the glasses off when the vision will be especially fuzzy, and the maintenance is very troublesome, I want to hear what you say, the feeling of wearing contact lenses Answer Long term wear of contact lenses will cause the main manifestations of the following aspects of the eye: 1, eye resistance decreased. Contact lenses will make the cornea unable to contact the air, the eye will be hypoxia, similar to the body plateau reaction situation, can not be normal metabolism, resistance to decline. 2, leading to visual fatigue, dry eye. Long wearing contact lenses, visual fatigue, and even cause dry eye. Lead acid eye itching, foreign body sensation, much gum, dryness, burning eyes and blurred vision. 3, cause eye allergies.

Contact lenses wear off the cornea and may cause severe consequences for corneal epithelial detachment or perforation. Some contact lenses and concavity convexity corneal discrepancies, irregular corneal abrasion, corneal ulcer, irreversible vision loss, even after treatment will leave white spot on the cornea. 5, cause eye paralysis.

Many patients suffer from ulcerative keratitis and are unaware. 6, corneal aging accelerated. Wearing soft contact lenses at age 20, 10 years later, the corneal endothelial cell density is equivalent to that of 60 year old people and will not be able to undergo any eye surgery, even if cataracts develop in old age. 7, myopia deepened, affecting the image.
