30/20 vision

**30/20 Vision**

30/20 vision refers to a measure of visual acuity that is better than the standard “20/20” vision. While 20/20 vision means a person can see clearly at 20 feet what an average person is expected to see at that distance, 30/20 vision indicates the ability to see at 30 feet what a person with normal eyesight can only see at 20 feet.
