What are the dangers of contact lenses

I believe that many myopic friends have come into contact with contact lenses. Contact lenses are also a tool for correcting vision, but if you wear contact lenses for a long time and pay attention to some details, it may cause some health problems, especially poor hygiene can easily lead to keratitis.

1. Contact lenses are one of the effective tools for correcting vision and have been proven to be reliable by tens of millions of wearers. There is no information to show that wearing contact lenses will affect your health when professional fitting and standard care are followed. However, contact lenses are medical devices and must be worn according to the advice of professional fitters.

Contact lenses are Class III medical devices that come into direct contact with the cornea. Wearers must select professional contact lens brands with quality assurance. It is recommended to choose regular professional eyewear stores and online eyewear malls with professional optometry qualifications. Also have regular eye exams to ensure long-term eye health.

2. Contact lenses themselves will not cause infection. Only when the lens is not clean, deposits on its surface may cause health problems. Substandard hygiene or improper use are common causes of keratitis and conjunctivitis. The shorter the lens wearing period, the smaller the chance of deposits and complications, and the healthier the lens will be when worn.

The shorter the lens replacement cycle, the less deposits there are and the lower the chance of infection or allergy. In order to make contact lenses safer and healthier for consumers, Xiaoke recommends choosing contact lenses with a short replacement cycle, such as: healthy daily disposable or two-week disposable contact lenses.

3. It is best to wear contact lenses and frame glasses alternately

Xiaoke recommends: Do not wear contact lenses for more than 8 hours, and it is best to alternate with frame glasses. You must take off your contact lenses before going to bed, because the cornea gets oxygen and moisture through tears. When people sleep, the tear secretion is too little and cannot fully moisten the eyes. The eyes will become dry and astringent, and oxygen cannot be obtained from the tears.
