Cosmetic contacts are not for everyone
Since the appearance of contact lenses, more and more consumers love, whether short-sighted or normal vision consumers use it to increase the level of appearance, matching makeup. But in fact, "color contact lenses are not suitable for everyone, beware of the possibility of complications, when choosing to wear, must be careful." If not used properly, there will be eye complications, so how should we choose?
There are three main uses for contact lenses: one is for correcting refractive errors, the other is for treating eye diseases, and the third is for cosmetic purposes.
Contact lenses for eye disease treatment usually do not cause serious complications because they are used under the guidance of a doctor. Contact lenses used to correct refractive errors, which require an optometry test, are used at least partly under a doctor's guidance, and serious complications are rare. For color contact lenses used for cosmetic purposes, the chances of serious complications are significantly increased due to the "free" trading and "arbitrary" use in China, and the uneven quality.
What are the manifestations of eye injury?
Specific damage to the eyes is mainly as follows:
One is to affect night vision: because of the color around the contact lens, the diameter of the circular hole left in the middle is fixed, but the pupil of the human eye needs to expand or shrink with the brightness of the light. At night, the pupil of the human eye is usually larger than 6mm. Therefore, long-term wear of this kind of color contact lenses, the range and clarity of vision at night can be affected.
The second is corneal edema and corneal mechanical injury: color contact lenses prevent the cornea from getting oxygen from the air, corneal hypoxia causes corneal epithelial cells edema and easy to flake off, so that wearing or removing the lens is easy to cause mechanical damage to the corneal epithelium. Such as red eyes, fear of light, tears, see things blurred.
Three is giant mastoid conjunctivitis: mainly lens and conjunctival contact, repeated friction stimulation when the eye is closed, or allergic reaction to the lens itself or disinfectant potion. Such as eyelid conjunctiva visible red pomegranate seed like protuberance, serious manifestations of red eyes, itching, secretion, wearing a mirror after the lens shift, blurred vision, foreign body sensation, etc.
Four is the leakage of color substances and damage the eyes: because the color of color contact lenses is infiltrated into the lens, if the production technology is not up to standard, there may also be the risk of leakage of color substances and damage the eyes.
When matching contact eyes, do the necessary examination and consultation first. Be sure to buy qualified products that have been tested and produced. And carefully read the product instructions, ask the inspector about the use method and matters needing attention. Avoid wearing it over time, preferably not overnight. Regularly go to the matching place to check whether there is any damage to the lens. Also, never wear colored contact lenses in windy environments or while swimming.
