Vision correction refers to the correction of vision loss through optometry or surgery, which can help people with vision loss achieve normal vision and improve their quality of life, and is mostly used for people with refractive errors. The common clinical causes of vision loss include myopia, hyperopia, astigmatism, and other refractive errors. Patients can clarify their refractive status through optometry, and then correct their refractive errors through prescription lenses to improve their vision. For adult patients with refractive errors, refractive surgery is also available to correct refractive errors, such as corneal laser surgery and intraocular lens implantation to improve vision. It is recommended that patients with vision abnormalities seek timely medical attention to assess their condition and choose the appropriate treatment under the guidance of their doctor.
