Low Vision

Some people cannot see the things they need to see even though they are not blind. Their problem is low vision.  Low vision refers to impaired vision that does not improve through medicine, surgery, or ordinary corrective lenses. Individuals with low vision find it difficult or impossible to do many everyday tasks. For example, they may be able to walk unaided but not see someone's face.  Low vision is not blindness, which is the absence of useful vision or light perception.
