What is the uncorrected visual acuity of high myopia?
Myopia can be classified as mild myopia from 200-400 degrees, moderate myopia from 400-600 degrees, and high myopia as above 600 degrees. What is the uncorrected visual acuity for high myopia? There is no clear pattern for this because a visual acuity of 0.1 may be corrected to 1.0 with just 50 degrees, or it might not reach 0.5 even with 1000 degrees. Therefore, uncorrected visual acuity is not a standard measure for high myopia. The level of uncorrected visual acuity depends on the condition of the eye's axial length and diopter. If the change in the axial length is not significant, a minor uncorrected visual acuity is not crucial, and the required correction might be very low. Conversely, the longer the axial length, the higher the correction needed might be.
