What should one do if something works for them, but scientific evidence suggests otherwise? Tough to say.
However, if you experience eye strain after prolonged computer use (as I do), consider a blue light filter glass from Amazon. I recommend the ones with a strong orange tint. They're also available as clip-ons. Give them a shot and see if they alleviate your pain. If they don't help, return them. Essentially, you're making a no-risk investment. In the worst-case scenario, you lose nothing, but in the best-case scenario, it could remedy your eye strain, just as it did for me.
