I think there's pretty much only truth to that. I had dry eye/eye strain from my first LED monitor which was a macbook back in 2010 only for 3 weeks but I was young back then. My dry eyes/eye strain officially became a chronic problem 7 months ago when the weather got cold and all of sudden we were getting rains everyday here in southern California. THere are different pollens for every season weather. On top of that, some family member of mine brought home huge amount of flower and kept it in the house for 5 days making the house smell unbearable. My eyestrain threshold has been so low ever since, to the point where I am turning my screen down to 0% brightness + plus another brightness slider to lower brightiness + influx basically turning down blue light as low as possible. THe newest thing I am trying now is lowering the contrast to 30% lower than the default, this seems to help a bit more as well.
So pretty much with the theory (if proven) in mind, the environmental supremacists/LED fanatics could legitimately claim that LED doesn't cause any problems and that we should have our auto-immune disorders fixed first.... am I correct?
anyways I am going to take a look at your subreddit post now. Thanks a bunch!
