To be honest, I'm not sure just how much of an exception me and my eyesight is to the norm. But certainly from what I see already on your site it is just red on black which creates problems for me. Having said that - it's a bit difficult to explain but - the red/black reminds me of a more generic difficulty that I personally have with a lot of high contrast pages. I used to download stuff from (for example) an old rocketdownload site which had a horrible 'sickly' green background (not sure if it exists anymore) but I invariably had to stop browsing because it really did create a very annoying irritation for me as well as my not being able to read the site.
