Wearing contacts will definitely not cause myopia, but there are two common causes of myopia: first, congenital genetic factors, if the parents are highly myopic, the next generation is more likely to be myopic. Secondly, bad eye habits, which are usually seen in children or adolescents, and wearing contacts will certainly not lead to the appearance of myopia. However, from a health perspective, ophthalmologists generally do not recommend wearing contacts because the oxygen permeability and breathability of this material is very poor, and long-term contact with the cornea and conjunctiva is likely to cause complications such as infectious keratitis or conjunctivitis after a long period of time, so it is not recommended to wear contacts.
