Just a quick suggestion for the computer. I to have vision issues with it, you may want to try a privacy filter over your lcd screen. They help reduce eye strain I find, also you could try using a program f.lux which has been mentioned in this forum. It softens the intensity of the lighting and can adjust by time of day.

For a cheap experiment for fluorescent lights, look on some online retailers for safety glasses by uvex with the Vermillion tint. Some use those for light and monitor sesitivity. I am experimenting with them this weekend, pretty cheap to try.
