With 275 degrees of myopia, the visual acuity will not exceed 4.6, but the specific visual acuity results will vary depending on each individual’s accommodation. The higher the degree of astigmatism, or the different axial positions, the greater the impact on visual acuity. In addition, each person’s visual acuity results are not fixed, and are susceptible to fluctuations due to external factors, such as dry eyes after excessive eye fatigue, which may cause transient blurred vision, and different vision inspection equipment may also lead to different results.
