I guess I have to speak up as every one made their mind and knows how the blue-blocking glasses are useless placebo gimick made up to take your precious 20$ from you.
I developed an eye pain condition around 14 years ago in university years, my eye sight was not really degrading but I get physical tension turning into pain in the eyes if I look at the screen for about 3-4 hours. I know that I still have this condition because sometimes I forget my glasses to the office and I have to take breaks much more often than otherwise. With the glasses I can work all day, then play video games, watch movies etc without feeling anything.
One thing I want to add is that there are seems to be different types of these glasses as I bought about 10 pairs and 2 of them also didn't work for me. So when I need a new pair I just take the one I know is good and ask optician if they have exactly the same type of filter.
So if the research says there isn't enough evidence it's fine, do more researches and find out exactly what happens here, but don't go around and tell how it's all made up and not helping anyone.
