275 degrees myopia is 4:00

There is no direct conversion relationship between 275-degree myopia and visual acuity, so it is generally impossible to give an accurate conclusion.

Myopia refers to parallel light entering the eye and focusing in front of the retina, resulting in unclear imaging on the retina. A patient's 275-degree myopia belongs to the eye diopter. There is no direct conversion relationship between diopter and sharpness of vision, which expresses vision. Moreover, due to certain differences in individual development, there may be certain differences in vision for the same degree of myopia, so it is generally impossible to give a direct conclusion.

Patients can use logarithmic eye charts, dilated optometry and other medical means to check eye vision, and accurate results can generally be obtained.
