Thanks for pointing this out, George. Of course there is a wide range of vision impairments - each with its own needs. I just wanted to keep the answer short and simple. My suggestion was: imagine yourself, what help do people need with certain disabilities. Besides this I gave a few examples illustrating this - as a first approach to accessibility. All the other posts here were correct, but it seemed to me, they have had just too much information for a beginner.
