Visual acuity
A measurement of how well you see in front of you. Visual acuity of 20/20 is considered “perfect” vision. 20/20 visual acuity means you can see something 20 feet in front of you what can normally be seen at 20 feet. If you have 20/50 visual acuity, it means you need to be 20 feet away from an object that someone with perfect vision can see 50 feet away.
