When wearing contact lenses, attention should be paid to the following points:

　　1. Before wearing contact lenses, it is important to ensure that the eyes are not congested or visibly dry, and that there is no discomfort. Only then can contact lenses be worn.

　　2. Before wearing contact lenses, it is necessary to wash hands with soap and then take out clean contact lenses to wear. If there is a foreign body sensation or pain in the eyes after wearing contact lenses, be sure to remove the lenses and do not wear them temporarily. At this time, frame glasses need to be used to correct vision. We still need to go to the hospital for a check-up to rule out any issues such as keratitis.

　　3. Contact lenses should not be worn for more than 8 hours during the day, as wearing them for too long can cause hypoxia in the cornea, which can easily lead to the shedding of corneal epithelial cells. Therefore, the time for wearing contact lenses should be shortened as much as possible.

　　4. After removing contact lenses, be sure to clean them thoroughly and soak them in a care solution. Try not to wear contact lenses every day and minimize the time and days of wearing them.

　　5. People with contact lenses need to prepare a pair of frame glasses for alternate use.
