Poor vision is the loss of vision that makes everyday tasks difficult. A person with visual impairment may find it difficult or impossible to accomplish activities such as reading, writing, shopping, watching television, driving or recognizing faces.

Losing vision does not mean giving up your activities, but it means finding new ways to do it and that requires a person’s patience and desire to follow life normally.
