If you have insomnia (specially sleep onset insomnia where it's hard to get to sleep, not the kind where it's hard to stay asleep) or delayed sleep phase disorder (what I have) they can be helpful
They're not the specific glasses typically used on the studies (uvex skyper glasses made by honeywell), but those have a hard nose bridge which hurts my nose if I wear them for the durations the studies were on, and a guy did independent testing for a bunch of the blue light blocking glasses and found these did slightly better while being much more comfortable :)
If anyone has questions or would like me to grab the study or the webpage for the guy who did the testing lemme know and I can go find the links :)
Edit: I forgot to mention, a lot of people actually really like these (yellow tint glasses) because some feel they increase their contrast perception. So they're sometimes worn when motorcycling on a rainy day, or other times where more contrast might be helpful. For me it feels subtle, but my dad immediately commented on it when he tried them.
