Business agency on February 6 hearing wearing a pair of blue or gray colored contact lenses, or a pair of black eyes to see the darker and bigger "US pupil", are now considered by the beauty Meimei Eyes for extra points. For convenience, some people buy "american pupils" on the Internet and in small optical shops. However, the State Food and Drug Administration recently released a message saying that in the future, color plain contact lenses (commonly referred to as “US-pupilsâ€) will be formally included in the scope of medical device supervision. If no medical device registration certificate is obtained, production and sales will not be allowed. Ophthalmologists said that "the United States pupil" can be worn but carefully selected cautiously, should be standardized eyes, follow-up review and other links, once found problems in the wear process should seek medical advice.
"The United States Hitomi" has a wide range of risks. The reporter found that various brands of "Mizutori" can be seen everywhere on shopping websites and street shops. Some are said to be Japanese-made, some are said to be Korean-made, and many are poorly packaged. Even vague, the price is even more expensive, some less than 30 yuan a pair.
"Color flat contact lenses are of varying quality, and poor quality products are harmful to the eyes. Even if it is a qualified product, because the lenses contain pigments, their oxygen permeability, light transmittance, and visual field are worse than those of ordinary contact lenses. Wear them with care." affiliated to Sun Yat-sen University Associate Professor Yang Xiao of the ophthalmology hospital told Xin Express reporter that there are some inferior products on the market. The dye is only applied to the surface of the contact lens and is in direct contact with the eyeball. The printing and dyeing process is rough and the surface is uneven, even though the naked eye is not noticeable. Decolorization may even lead to ocular surface staining. The resulting irritations can also lead to eye congestion and inflammation. A few extremely severe individuals may cause corneal hypoxia, eye infections, corneal ulcers and other serious eye diseases, and may even cause blindness.
She pointed out that the current color contact lenses mainly through the "sandwich" process, the dye layer sandwiched in two transparent lenses, to avoid contact between the dyed layer and the eye; also through a special process evenly pressed the dye in the entire lens. In both processes, the dyes are not in direct contact with the eyeball and are safe. However, the pigment layer will affect oxygen permeability and metabolism, but also absorb light and reduce light transmittance. Many people feel that wearing a "US pupil" will dim the light is the truth. Different colors have different wavelengths and their light transmittance also varies. In addition, compared with ordinary contact lenses, the "US-pupil" optical zone is less, more pigment, it will inevitably narrow the field of vision.
Can not be worn every day or for a long time not long ago, Lin Lin in the "'Mizuta's Daren" Mary's lobbying under the "US pupil." After playing all night at a friend's birthday, Lin Lin, who had been very careful, forgot to go to bed by picking up the “pupil.†When she wakes up, she is naturally worried. However, the next day she did not feel any discomfort with her eyes, so she felt that she should pick the "US-pupil" every day is only a minor issue. After wearing a "mei pupil" for three days in a row, she developed eye pain, tears, and photophobia. She thought she had a corneal ulcer after attending the doctor. She was associated with her wearing a "beautiful pupil" for a long time.
Based on the color contact lens lenses containing pigments, affect its oxygen permeability, light transmittance and visual field, Yang Xiao believes that color contact lenses should not be worn every day or for a long time, otherwise it is easy to occur such problems Linlin. Long-term wear "beautiful pupil" causes long-term hypoxia of the cornea, no abnormal symptoms at the beginning, but the long-term hypoxia cornea is prone to corneal ulcers, after the expansion of the cornea will be dissolved, medication can not cure, can only rely on surgery. “Wear occasions, wear on certain necessary occasions, and remember to take them off at night.†Experts cautioned that if persistent redness, pain, photophobia, tearing, increased secretions, blurred vision, etc. occur during wear Stop immediately and go to a professional institution to find an ophthalmologist or optometrist to check the eyes.
Wearing the "US-pupil" at least half a year to review Yang Xiao told reporters that the first time wearing contact lenses, including "the United States pupil" should not be too casual, should go to ** eye examination glasses. "There are too many types of contact lenses and different techniques. They should choose the conditions that suit their eyes. This requires professional eye examinations, try-on procedures, and eye diseases that are not suitable for wearing contact lenses," she said. Different tear secretion conditions, suitable for contact lenses with different water content; eye shape is different, the choice of contact lens base arc is also different. It may not be necessary to buy an eye every time you buy a “beautiful pupil,†but at least when you wear it for the first time, you should do professional eye testing.
“Some people have done professional eye examinations at the first glasses and selected suitable contact lenses at the advice of a professional doctor. Usually, it is possible to facilitate direct purchase, but it is also necessary to review regularly because the condition of the eyes is not Immutable, there will be changes after the adjustment or replacement of the use of contact lenses." Yang Xiao pointed out that some people wearing "US pupils" and other contact lenses for a long time will appear new blood vessels, which prompted its wearing lens oxygen permeability Not enough, should choose better oxygen permeability of the lens, but this is invisible to the naked eye, only to check the eyes can be found. In addition, as the age increases, the secretion of human tears will decrease, which requires adjusting the lens parameters of the contact lenses. These conditions can be discovered in a timely manner through regular review and adjusted in a timely manner. Therefore, experts suggest that wearing a "US-pupil" and other contact lenses should be reviewed once every six months; first-time wearers should review the first month and three months, and then review once every six months thereafter.
After wearing a mirror first make-up, first remove the mirror and remove makeup after a lot of crush training on a "fire chestnut" kung fu, keep long nails, wear false eyelashes also wear contact lenses, but do not know this is a dangerous act. Laughing and laughing love to wear "beautiful pupil" every day, but after wearing it for a while, she feels unclear sight. To the doctor at the optician's center, she saw scratches on her lenses. Laughing and laughing thus demonstrates his own practice of wearing a "female pupil". Obviously, she does not know how to use the finger to wear glasses, and her long fingernails scratch the "pupil".
Yang Xiao told reporters that many people who wear the "Beauty Hitomi" are amateurs. They also have a lot of make-up habits. Once they make-up, they should wear makeup after the mirror first, and then remove the makeup after removing the mirror. In order to increase the oxygen permeability of some contact lenses, silicone molecules are added to make it easier to adhere to oils and fats. Cosmetics are mostly lipids. Once attached to such materials, they are not easy to remove, resulting in wearing the lens more blurred, so use this kind of contact lens. When the lens of the material is used, it is not possible to remove the makeup first and then pick the lens. "When wearing a mirror, apply two fingers to open the upper and lower eyelids to prevent the lens from touching the eyelashes. When you pick the mirror, you must open your eyes and look upward. Move the lens to the lower eyelid and gently remove it with your fingertips. "She also stressed that do not use the method of squeezing the eyeball to pick up the "United States pupil" and other contact lenses, this oppression of the eye, in the long run may lead to keratoconus, resulting in irregular astigmatism.
The lens box should be replaced every 3 months â— The contact lens wearer starts three things every morning (three-look): his eyes look good, his eyes feel uncomfortable, and his eyes look good.
◠Contact lenses daily care four-fold: Clean → Rinse → Disinfection → Store.
â— The care solution should be used within the validity period. If it is not used up within the use period (usually 90 days) after the bottle is opened, it must be bottled and discarded.
â— Do not contaminate the care solution. Do not touch the mouth of the care solution bottle with your finger, lens, or mirror box. Place the bottle lid open and place it upwards.
â—Used care solution should be promptly poured into the net and should not be reused.
â— Avoid contamination of the mirror box. The mirror box is highly contaminated and can contaminate the glasses. The mirror box should be washed daily with hot water, physiological saline, or a care solution, and the mirror box should be replaced every 3 months.
