Low vision is considered a significant vision impairment that usually results from serious eye disease or an injury. The vision loss, which is characterized by either reduced visual acuity (to 20/70 or worse) or reduced field of view, can't be fully corrected with glasses, contact lenses, medication, or surgery.

 

Low vision can affect both children and older individuals but is more common in the elderly, who are at greater risk of eye diseases such as glaucoma, macular degeneration, and cataracts, which are some of the most common causes of the condition.
