There are lots of books available for blind children, and many card and board games (Rummikub, monopoly, and uno, as well as standard card decks) can be found in Braille versions. :) I loved Monopoly at about that age. My sister preferred Uno by then. (Neither of us are blind- my husband is. We have Braille Rummikub and Monopoly.)

Personally I would suggest clay- I loved it at a kid and still do now. It's all touch and feel and can even be therapudic.

Basketball with sound so he can hear where it’s at. As a braille transcriber I’ve adapted board games with textures instead of colors. Also find out if there are any video games he can play. Many blind people play video games.

Hi there! I would definitely consider these $1 people. In a couple days they will be launching a revolutionary version of their first product which is called MyEye 2. It's a tiny camera attachment that can snap to any kind of glasses frame and whispers into your ear what is around. It can also read text from any surface. Street signs, emails, newspapers any form of text you can imagine. It really is one of the best $1. I don't know what your budget is but after being withness how this wearable tech can change the way visually impaired people live, I would definitely recommend it. I believe it would make a great gift for an 8 year old.

Wonderbaby.org has a few different toy lists. I think they tend to be geared towards younger kids but a couple of them have stuff appropriate for a a range of ages.
