Introduction
After developing extreme myopia, blindness may occur. Extreme myopia generally refers to myopia exceeding −10.00 diopters. As the degree of myopia increases, visual acuity progressively declines, and complications such as vitreous opacities, retinal atrophy (e.g., peripapillary atrophy), macular hemorrhage, and retinal detachment may develop. Even with treatment, restoration of normal vision is often difficult.

Myopia (nearsightedness) is a relatively common ocular condition in daily life. Prolonged use of electronic devices—such as smartphones and computers—in everyday activities is a major contributing factor, often leading to the development of myopia and adversely affecting normal daily life and work performance. Can extreme high myopia lead to blindness?

Can extreme high myopia lead to blindness?

Yes, blindness is possible with extreme high myopia, which is generally defined as myopia exceeding −10.00 diopters. As myopia progresses, visual acuity progressively declines, and serious complications may develop—including vitreous opacities, retinal atrophy, macular hemorrhage, and retinal detachment. Even with treatment, full visual recovery is often difficult or impossible. It is advisable to consume carrots in moderation as part of a healthy diet and to avoid staying up late.

Blindness primarily results from pathological changes associated with high myopia in the fundus, such as myopic macular degeneration, macular hemorrhage, and retinal detachment—severe complications that can cause varying degrees of vision loss, potentially culminating in complete blindness. Therefore, individuals with extreme high myopia should adopt appropriate eye-use habits and strive to slow the progression of myopia. Vigorous physical activity should be minimized to reduce the risk of serious complications like retinal detachment.

Regular fundus examinations enable early detection and prompt treatment, helping to control disease progression at an earlier, milder stage. We hope this information proves helpful to you.
