I have used different kinds of blue light filter glasses for almost two years, but I remember the day I got my first ones. I had a hard time falling asleep. I had minor bad habits, like drinking too much coffee and staying on the computer too far in the evening. But these habits were pretty hard to change. I needed to work on the computer and did not know how to survive without coffee.

Every night I went to bed at around 11 pm, lay awake for one hour, got bored and took out my phone or iPad (even though I knew I wasn't supposed to!). Then stared at the screen for too long and fell asleep at 1:30-3:00 am, depending on the day. And you can guess that getting out of bed at 7 am was displeasing.

I first bought the anti-blue light glasses as computer glasses but started wearing them all day at home. They did not help straight away, but over the first week, I noticed that I wanted to go to bed because I was tired. Before, I always got more active during the evening and going to bed just seemed stupid, but I knew I needed to get the sleep. Fast forward a few weeks, I always got to bed at the same time, fell asleep pretty much instantly, and woke up at the same time without an alarm clock. It felt like my body was in sync. (and btw as a side note, my first blue blocking glasses were not so good and let some of the blue light in, but they still worked)
