I would wait on close-focus stuff, myself. But there's plenty of non-visual work you could do on math (skip-counting, mental math, oral drill, guessing games and all sorts of other math games) ... and you could probably find lots of interesting games to do for reading that wouldn't involve visual work as well... rhyming games, alliteration practice, parts of speech, reading aloud for vocabulary and comprehension, etc.).
