There is no clear correlation between bare eye vision and the degree of vision, or there is a very weak correlation, because everyone’s adjustment power and the depth of focus and depth of field are different, so the degree of nearsightedness or farsightedness that results has a different degree of impact on vision. For example, some people may have 100 degrees of myopia and still see about 0.8, but some people with 100 degrees of myopia may only see about 0.3-0.4, indicating that the depth of focus or depth of field of the eye is not as great as seeing 0.8, so the resulting 100 degrees of myopia has a greater impact on vision. In addition, it is possible for children with 100 degrees of myopia to still see 1.0, this situation may exist pseudomyopia component, need to go to the hospital for dilated eye examinations to eliminate eye fatigue and pseudomyopia, vision can also be restored to a stable situation.
