If you see blurry images, do you have impaired vision?

Blurred / impaired. This is a tricky question. Some people can have 20/20 vision, but the images are not crisp, and may seem blurred to the person. To define the vision as "impaired" means that the best corrected vision is poor to the extent that it interferes with routine activities of living. A person would not have to be legally blind (20/200) to have "impaired vision". Impairment depends on a person's visual need.
