How many degrees is 0.25?

The visual acuity of 0.25

usually refers to the decimal record of uncorrected visual acuity checked by logarithmic visual chart, and the degree is the result of refraction. There is no complete correspondence between visual acuity and refractive degree, and there is a fluctuation range. Due to the different eye adjustment ability of each person, there may be a gap in the degree of myopia. It is recommended that patients check the specific degree by refraction.

Avoid excessive use of eyes in life, do not look at electronic products for a long time and stay up late. If the visual acuity is lower than normal value, wear glasses to correct their visual acuity.
