Contact lenses can be worn for most sports, but for sports such as diving and swimming it is best to avoid contact lenses, and if the sport is prone to contact with sand and dust, it is best to avoid contact lenses as well. Contact lenses can serve to improve the patient’s appearance as well as facilitate sports. It is possible to wear contact lenses while playing most sports. However, it is better for patients not to wear contact lenses when engaging in sports such as diving and swimming because the disinfectant components and bacteria in the water may cause eye infections if they come in contact with contact lenses, and the chemicals may not only damage the lenses, but may also have a toxic reaction to the cornea. Patients who will be exposed to a lot of sand and dust during sports should not wear contact lenses because once the sand and dust enters between the lens and the cornea, it is easy to rub the cornea with the friction between the lens and the cornea. Patients are advised to consult the ophthalmology department of regular hospitals and seek prompt medical attention if they feel unwell.
