Vision 2.0 is normal?

Visual acuity 2.0 refers to central vision, which is generally normal.

Usually, vision of 1.0 or above is considered normal, and vision of 2.0 indicates that the subject's vision is very good, visual function, visual acuity and resolution are at a high level. However, the vision test often done in clinical practice is distance vision. People with very good distance vision may be prone to visual fatigue and blurred vision when looking at near objects. Professional optometry is recommended to rule out hyperopia.

Usually, attention should be paid to developing good eye habits, doing good eye hygiene, doing more outdoor sports, ensuring adequate sleep and maintaining good vision.
