The normal range of vision for a 5-year-old child is about 0.6 to 0.8. The eyes of a 5-year-old child are still in the stage of growth and development, and are not yet completely set, so there is still room for gradual development and improvement of vision. For example, when a child is born, the range of vision is still relatively narrow, with age, it will gradually from 0.2 slowly rise to 0.8 or so, to the age of 5, the visual acuity of about 0.6 to 0.8 or so. If parents find that their children have a series of symptoms such as blurred vision, eye fatigue, eye pain, etc., and suspect refractive error, they need to seek early optometry to clarify whether they have myopia. To summarize, parents should pay attention to observe the development of their children’s vision and have regular checkups.
