now more and more people want to get rid of the shackles and tend to take off the frame glasses, so more and more people wear contact lenses, and wearing contact lenses is also very exquisite. Let's see which seven kinds of people are not suitable for wearing contact lenses
1. Cold patients often have a large number of bacteria on their hands, they are easy to enter the eyes when people take off and wear glasses, causing infection.
2. People in the cold often accompanied by mild conjunctivitis, keratitis or retinal inflammation, wearing contact lenses will aggravate the inflammation.
3. Many cold drugs contain components that inhibit tears. The reduction of tears secretion will make contact lenses dry, reduce transparency, cause discomfort and affect vision.
2. Fever patients
In febrile patients, the resistance of eyes decreased, the secretion of tears decreased, bacteria multiplied in large numbers, and their metabolites accumulated between the cornea and the lens, causing bacterial corneal ulcer, etc.
3. Pregnant women
During pregnancy, due to the changes of endocrine function, the barrier function of corneal tissue decreased, and the tear secretion decreased. At this time, wearing contact lenses is easy to cause eye discomfort.
4. Primary and secondary school students
Primary and secondary school students are in a period of vigorous growth and development. The optic axis of the eyeball has not been shaped yet, but most of the ordinary contact lenses are not specially customized, which is easy to cause the curvature of the lens not to adapt to the cornea. If the contact lenses are worn too early, it will cause corneal wear, epithelial detachment, and even lead to corneal ulcer or perforation in serious cases.
5. Sensitive people
Contact lenses are easy to cause complications for people with seasonal or perennial allergic conjunctivitis, so it is recommended to avoid wearing them.
6. Long term outdoor work or cycling tour
The acceleration of air convection will make the lens dry and hard gradually, and the eyes will feel uncomfortable, so it is not suitable to wear contact lenses.
7. Patients with eye diseases
Patients with keratitis, conjunctivitis and severe trachoma are not suitable for wearing contact lenses.
