Whats the visual acuity equivalent to a 500-degree myopia?

If you have a need to measure your visual acuity, it is recommended to visit a formal hospital for measurement. If you do not develop proper eye-use habits in daily life and use your eyes for extended periods, it can lead to excessive eye fatigue and induce myopia. With a myopia of 500 degrees, the damage to visual acuity is relatively severe, often accompanied by symptoms such as blurred vision and visual fatigue. There may also be abnormalities such as poor night vision and flashes of light in front of the eyes, affecting daily work and life. Patients can undergo visual acuity tests, fundus examinations, and axial length measurements at formal hospitals to determine the severity of their condition through various tests.

500 degrees of myopia usually corresponds to a visual acuity of 4.2. Patients can wear glasses for intervention and need to visit the hospital annually for follow-up examinations to adjust the prescription of their glasses. They can also undergo laser refractive surgery or vitrectomy at the hospital to improve their symptoms. It is usually recommended to avoid wearing glasses for a week before surgical treatment to reduce irritation to the eyes. It is essential to develop proper eye-use habits in daily life, avoiding prolonged use of electronic devices such as tablets and computers. If you use your eyes extensively in daily life, you need to regularly close your eyes for a period of rest or gaze into the distance.
