There are currently three main methods used to correct refractive errors: wearing frame glasses, contact lenses (ok lenses), and laser surgery. Wearing frame glasses is still the most commonly used, and its disadvantage is that it affects the appearance. However, with the continuous advancement of technology, the spectacle frames are getting lighter and lighter. Wearing glasses is still the safest way to correct vision.

The advantage of a contact lens is that it has the least impact on image changes and does not affect the appearance. But it also has certain disadvantages, such as allergies, infections, corneal damage and so on. However, with the continuous improvement of materials, contact lenses have also become a reliable means of correcting refractive errors.

The principle of laser surgery for refractive error is basically the same as that of wearing glasses, except that the cornea is thinned by cutting the cornea to correct the refractive error. However, surgery is not recommended for children under 18 years of age.
