It's probably the combination of my astigmatism and my early stage cataracts and not the astigmatism alone. The blue is too dark. I'm using a two or three year old iMac with a 21 inch screen. I don't know what the resolution is, but it's very good. I have no trouble reading this thread in the Mudcat, even when the text size is the same as in the Faldingworth Live site, because there is very good contrast between the text and the background. But the background in the Faldingworth Live website is too dark and there's not enough contrast. It almost gives me a headache when I try to read it.
