High quality data is nice, but at some point one has to get on with one's own life, rather than wait for data. I bought a pair of glasses to filter out blue light on the advice of my dad (who has an eye problem and was recommended them by his doctor) and it has made a real difference - I can now do a full day's coding in front of my LED screen without feeling like my eyes went up against a cheese grater. YMMV
