Hi everyone,
Like others here, I've suffered from chronic eyestrain/LED strain for a long time. I've found that affixing laminate pouches to the monitor has helped reduce my eyestrain by 60-70%. I believe this is because the pouches diffuse and soften the light coming from the screen, which makes everything a little easier on the eyes.
Anyways, I've created a video to demonstrate the setup in the hope that it provides some relief for others in the same situation. It's not a perfect solution, but for me at least, it's helped a lot.
Cheers!
