1.0 eye vision is basically normal, but the presence of eye diseases cannot be ruled out.
When a child reaches the age of 8, his or her eyesight is basically fully developed, and his or her visual acuity can reach 1.0 or more. After adulthood, vision is mostly in a stable state, if there is no myopia problem, eye vision can reach 1.0 to 1.5, therefore, 1.0 eye vision is normal.
1.0 eye vision does not mean that there is no problem in the eye, some people with slight myopia or astigmatism will squint and tilt their head when checking their eyesight, resulting in an eye vision of 1.0, and some patients with glaucoma can also have a visual acuity of 1.0.
Therefore, a visual acuity of 1.0 does not mean that there is no problem with the eyes. If you feel uncomfortable with your eyes, you should go to the hospital for a detailed examination to clarify the health of your eyes.
