Are retina Mac displays and the 5k iMac display better for a low sighted user? I have very poor vision and I mainly use VoiceOver and JAWS when I use a computer or my iOS devices. I have some vision on my other eye and I am able to see and read text if the text is large enough and the text is white on a black background. My iPad Air 2 is great because I can use it in white on black, zoom and use VoiceOver all at the same time. I also like that the contrast seems very good. Good contrast is important to me. I only use my sight to read short texts. For anything longer VoiceOver is nicer.
I am buying a new Mac. I have Mid 2010 MacBook Pro that does not have a retina display. It is a great computer but the display is not as good as on my iPad. I'm thinking of getting a 27 inch iMac. However for someone like me is the retina display on a Mac a good investment? I have heard that some low sighted users who use zoom prefer the retina display. Certainly on my retina IPad the zoom works very well. Money is not a huge factor here. If the retina 5k IMac is superior for someone with poor sight and uses zoom and white on black and I will certainly get that one. As I mentioned earlier good contrast is important also.
I understand that the answer to this question depends largely on the level of my sight. However I would appreciate all comments from other users who have low vision or knows anything about this subject.
PS. This is my first post here. Thank you very much for any feedback.
