Glare is defined by the International Commission o n Illumination (CIE) as a “ condition of vision in which there is discomfort or a reduction in the ability to see details or objects caused by an unsuitable distribution or range of luminance or by extreme contrasts ”
Disability glare: loss and recovery • Onset of peripheral glare source produces large initial visibility loss (threshold elevation) • If glare source left on sensitivity improves (threshold decreases) until a steady state (continuous) glare sensitivity level is reached • Disability glare formulas generally refer to

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.
What line is 20 40 on the eye chart?
Line 1: If you are only able to read the big E, your vision is approximately 20/200. If you can read the T & B, you are reading 20/100. Line 2: This line is approximately 20/50. Line 3: This line is ~ 20/40. You need to be able to read letters this size to pass the vision test for your drivers licence in California.
