The term ‘20/20’ or ‘visual acuity’ is a measurement of the eye’s sight ability. It means that you can see at 20 feet what a ‘normal’ person sees at 20 feet.
If your eyesight is 20/100, you would see at 20 feet what a normal person sees at 100 feet. You would have to be that much closer of the object would have to be that much bigger for you to see it. In other words- distance would be very blurry!
If your eyesight is 20/10, you would see at 20 feet what a normal person sees at 10 feet! You would have super sharp eyes like a hawk!
Your visual acuity can be affected by your refractive state (nearsighted, farsighted or astigmatism), your eye health, and in cases if you have a ‘lazy eye.’
