What are the methods for vision correction?

Vision correction generally adopts methods such as wearing glasses, wearing orthokeratology lenses, laser treatment, etc. Symptoms of vision loss should be promptly treated by a doctor.

1. Wearing glasses: Glasses mainly add refractive lenses in front of the human eye's refractive system. Light sources can converge light on the retina through glasses, thereby obtaining a clear image and improving vision. This is a common method of vision correction.

2. Wearing orthokeratology lenses: Orthokeratology lenses are a method of refractive correction that can improve the naked eye vision of patients with myopia. They are worn at night and removed during the day, maintaining clear vision throughout the day and achieving a temporary vision correction effect.

3. Laser treatment: Laser treatment involves cutting the corneal stroma with excimer laser or femtosecond laser to change the corneal radius of curvature, corneal thickness, and corneal refractive state, achieving the effect of vision correction.

In addition to the above methods, vision correction can also be achieved through intraocular lens implantation surgery, which can improve vision and achieve the effect of vision correction. In daily life, it is important to develop good eye care habits, avoid staying up late, refrain from prolonged use of electronic products such as tablets and mobile phones, and avoid eye fatigue, which can lead to decreased vision.

You can eat more foods such as tomatoes, animal liver, and cantaloupe to supplement your body with vitamin A, which has an auxiliary effect on improving vision.
