Children can wear contact lenses, but mainly for older children, for example, keratoconus is a special contact lens that requires children over 8 years of age to wear it, which is relatively hygienic and effective. However, children under the age of 8 with high refractive error and no way to match frames can wear contact lenses, such as rigid contact lenses and RGP glasses, which can also be worn in younger children, mainly to improve visual effects and avoid amblyopia. When children are wearing contact lenses, they should pay attention to hygiene and safety to avoid rubbing their eyes which can lead to broken glasses and damage to the cornea. It is also easy to cause corneal infections if hygiene is not taken care of. Children can wear contact lenses, but it is important to pay extra attention to these issues when wearing contact lenses.
