Peripheral eyesight after stroke

My friend had a stroke and her peripheral eyesight has been affected.  I understand there is computer
programming that could be used to help her improve her sight.  Could you tell me about this and where it can be bought?

Jordan2, I also had a stroke that affected nothing except the peripheral vision on my upper left field.
There's a new device out on the market that can help.
It is FDA approved.
The website is www.novavision.com/
Hope this helps....
How long has she had this loss of vision?
