Many stars will wear contact lenses to increase the effect of eye makeup. People who pursue fashion also have great interest in contact lenses of various colors. However, such small and convenient lenses also have many taboos in use, do you know?
The biggest taboo of contact lenses is to wear them overnight. Under the condition that the cornea is originally anoxic and edematous, bacteria proliferate rapidly between the lens and the eyeball, which greatly increases the possibility of damage and infection of the cornea and conjunctiva, and makes the eye health at risk.
Wearing contact lenses when flying is very harmful to your eyes. The air in the cabin is dry and the cornea is easy to lack of oxygen, which may cause problems such as vision decline and corneal ulcer. In addition, the change of air pressure also changes the curvature of cornea, resulting in contact lens deformation, coupled with a long time of drying, the lens will become fragile.
It's best not to wear contact lenses when cycling or running. Air convection will accelerate the evaporation of water and make the lens dry gradually, which may damage the cornea and cause pain. If dust and other foreign matters enter the eyes, it is also easy to cause infection.
Contact lenses have relatively strict restrictions on the suitability of people. People who are not suitable for wearing contact lenses mainly include students, middle-aged and elderly people, patients with eye diseases, etc. these people are not allowed to wear contact lenses because they may cause multiple injuries to the eyes or further aggravate the disease.
Do not choose to use contact lenses if sanitary conditions are not guaranteed. As long as the direct contact lens, no matter the operation in the process of removing and wearing or the cleaning and care of related products, it must be ensured that the disinfection is clean and thorough.
