How good does your vision need to be to appreciate the high-resolution screen on the iPhone? How about 20/25 ... this video shows an iPhone being used as a vision screener!
20/25 as the limit makes this almost worthless (not threshold for most pts, and if you can't test threshold...). Until the dot-pitch really improves, near testing with computer generated optotypes is not good enough. Good idea though!
