0.8 How many degrees is your eyesight?

0.8 is only a visual acuity value on the eye chart. The corresponding degree can be myopia, generally in the range of 50 or 150 degrees, or it may be farsightedness in the range of about 300 degrees. There is no direct corresponding relationship between the specific degree of myopia or farsightedness. Because everyone's adjustment will lead to different degrees, the same vision, if the adjustment is very strong, it is possible that the degree will be relatively high. If the individual's regulatory power is poor, the degree of possible performance is quite low, so it should be combined to see.
