How many degrees is high myopia?

Generally, high myopia refers to a myopic refractive error exceeding 600 degrees. Patients with high myopia are advised to undergo regular fundus examinations to detect potential complications early and receive timely treatment as directed by a physician. The analysis is as follows:

High myopia is defined as a refractive error of 600 degrees or more. In ophthalmology, this condition is classified as pathological myopia, characterized by significant vision decline, visual fatigue, and other clinical symptoms. Corrected vision often fails to reach normal levels. With higher degrees of myopia, patients are more prone to develop fundus complications and retinal detachment. Once diagnosed with high myopia, patients should follow medical advice to wear corrective eyeglasses or contact lenses to prevent further progression of the condition.

In addition, in daily life, it is important to maintain good eye hygiene and avoid prolonged near-work activities to reduce eye strain.
