A person becomes visually impaired when their vision cannot be corrected to an acceptable standard. Macular degeneration, cataracts, and glaucoma are the leading eye diseases that lead to visual impairment in the elderly. It is difficult for someone to get used to vision loss, and they will often need support to help cope with their new reality. Tasks that they were used to performing with ease may now be beyond their abilities. This can lead to dangerous situations without the aid of a caregiver.
