Suggestions for adaptions at work

I work in a mainstream primary school.  I've got a management of absence meeting next week because I've recently had a viral infection. While I was in the meeting I was going to mention that the amount of fluorescent lights is affecting my light sensitivity. I'm going to the opticians next week to get some prescription glasses with blue light filters built in. Can anyone think of adjustments that my school could make that won't cost the earth?
