High myopia can also wear contact lenses, whether it is low, moderate or high myopia. Just ophthalmologists do not advocate wearing contact lenses, contact lenses direct contact with the conjunctiva and corneal tissue of the eye, easy to stimulate conjunctival congestion, conjunctival follicles, papillary hyperplasia caused by dryness, grinding tears, fear of light and other discomforts. Wearing contact lenses for a long time will also cause hyperplasia of the giant papilla above the conjunctiva, forming giant papillary conjunctivitis. Contact lenses that do not breathe well can also lead to corneal degeneration, corneal dryness, and even the formation of punctate keratitis, which can then lead to severe vision loss. In addition, contact lenses do not have astigmatism, so they are not a complete solution to refractive problems.
