My mother suffers from pattern dystrophy, similar to macular degeneration but without an available treatment. Though she is now legally blind, she has practical vision remaining. For reading, she uses several visual aids -- large iPad for ebooks, magnifying glasses, and has a very large screen television used both for entertainment and as an extended computer monitor.
