Zhongxin Online Hai, December 13 (Chen Jing, Xu Lanqing) "Contact lenses are convenient and beautiful, often regarded as ordinary goods, but in fact, contact lenses are the third class of medical devices, especially decorative contact lenses, should be very careful when buying and wearing." Yang Xiaobo, chief physician of the Department of Ophthalmology of Shanghai Medical University Hospital, said bluntly in an interview with reporters on the 13th that the improper wearing of contact lenses will indeed have an impact on eye health.

It is reported that in the face of different market demands, today, contact lenses have more tricks, different colors, materials, functions, etc. to give beauty lovers more choices. Do contact lenses have an impact on eye health? What to look out for when choosing and using contact lenses on the web? In this regard, Yang Xiaobo said that glasses should be chosen as much as possible. If you choose to wear contact lenses, be sure to pay attention to eye hygiene.

Yang Xiaobo told reporters that because there are no blood vessels on the surface of the cornea, 5% of the oxygen on the surface of the eyeball is absorbed from the air, contact lenses reduce the oxygen content of the eye surface, and the eyeball is in a relatively hypoxic state. Long-term wearing of contact lenses can easily lead to problems such as dry eye and acute keratitis. Not taking off contact lenses at night and wearing glasses for several days in a row have huge health risks. At the same time, if the degree of contact lenses worn is not appropriate, it will cause symptoms such as dizziness and dizziness, and severe ones will affect vision, resulting in irreversible consequences such as deepening the degree of myopia.

The expert said that many people buy decorative contact lenses online, the safety hazard is greater: irregular decorative contact lenses, compared to ordinary contact lenses will be thicker, oxygen permeability is worse, the material is harder, the friction with the eyes will be greater, and the damage to the cornea will be greater.

Yang Xiaobo reminded the public that if it is the first time to wear contact lenses, it is best to conduct a professional eye examination before purchasing, conduct a comprehensive assessment of the degree of the eye, cornea conditions, etc., and judge whether it is suitable for wearing contact lenses; when buying contact lenses online, we must pay attention to whether the qualifications of the merchant meet the standards and choose regular sales channels. In addition, the public should grasp the correct posture of wearing contact lenses, ensure hygiene in the process of wearing or taking off, do a good job of finger cleaning, if you need makeup, remember to wear glasses before makeup.
