Is there any harm in taking cosmetic contact lenses for a long time?

Wearing lenses for a long time every day will lead to hypoxia in corneal tissue, and it is easy to reduce the wearing comfort due to lens precipitation or lens dehydration. More than 80% wearers will have symptoms such as jealousy, visual fatigue and dry eyes after wearing 13 hours continuously, and some wearers have to take off their lenses and temporarily stop wearing them. Therefore, it is recommended to wear glasses for no more than 8 hours a day, and no more than 12 hours at most.
