Is a vision of 0.8 normal?
Vision screening during the physical examination showed only 0.8 visual acuity. I occasionally experience blurry vision in daily life. Is this level of vision considered normal? Could there be a problem with my eyes, and should I go to the hospital for further examination?

Whether a vision acuity of 0.8 is considered normal depends on the specific circumstances. For adults, it is generally not considered normal, while for minors, it may be within the normal range.
In the standard vision criteria, 1.0 is regarded as normal visual acuity. An adult with vision of 0.8 has slightly lower than normal visual acuity, which may indicate mild refractive errors such as myopia, hyperopia, or astigmatism. These conditions may be caused by poor eye habits, genetic factors, or other reasons. Although a vision acuity of 0.8 is not significantly different from the normal standard, without proper attention and correction, it may lead to further deterioration of vision.
However, different age groups have different standards for normal vision. A child's vision is not yet fully developed, so a vision acuity of 0.8 may be considered normal. If a child's vision remains at 0.8 or below and does not improve with age, timely medical attention is recommended to rule out eye diseases or refractive errors.
In daily life, it is advisable to maintain good eye habits, such as avoiding prolonged screen time, maintaining an appropriate reading distance, and engaging in sufficient outdoor activities, which can help maintain and improve vision.
