Impressive, and interesting, but with one problem: I, like a lot of people, have floaters in my eyes (http://en.wikipedia.org/wiki/Floaters). When I focus on a single point and don't move my eyes around, they tend to congregate at the centre of my vision and in Spritz's case block the words that are being shown.

Potentially, a brief pause every 50 words or so would make sense in order to quickly move my eyes and unblock my vision, though obviously at the cost of some words per minute.

Having had detached retinas that were caught early and tacked back in place by a laser I too have a heavy dose of floaters from blood leaking and clotting. It's more like drifting and jerking, variably transparent clouds than what people usually think of with point or wiggler floaters. What annoys me the most with this problem is their motion into and out of my foveal region in response to eyeball rotations and the resulting variation of tranparency. This especially bugs me while reading. Well, driving is worse but that's another topic.

What I immediately noticed with the Spritz demo was that since I wasn't moving my eyes there was no particular change in transparency in the foveal region once the little beasts settled into place. I found this a much improved situation which indicates that it is not the partial occlusion itself that bothers me but rather the constant changes in it due to moving my eyes about the page.

In brief, I like what this method does for my problem.
