Physiology of glare and readaptation (including age differences)

What is 20 - 20 Vision Test?
- Visual acuity is the most common clinical measurement of how your eyes function. It's usually one of the first tests taken during a comprehensive eye exam to determine how sharp your vision is. If someone has 20/20 vision, it means they can see the same amount of detail from 20 feet away as the average person.
