Review on Gudzws Kids Blue Light Blocking Glasses: Rectangular Digital Eyewear for Boys and Girls aged 5-12 by Andrew Roll

These are the only child sized blue light blocking glasses I could find. They are definitely kid sized. They fit my 4 year old and 7 year old well. The best part is that they stay put, so they don't have to be constantly adjusted. These glasses seem to block some of the light (I've looked at the LED light through the lenses and can see that the light looks warmer with the glasses) but not sure how much blue light they filter out. Anyway, my kids love them and wear them all the time. They even forget to take them off when playing indoors (without watching screens). The reason for 4 stars is that the red color is not as bright as pictured. They're more purple. I almost returned them because of this, but my son said they were fine (they look darker compared to the light pink ones I bought for my daughter, so I guess that's why he was okay with that). I figured if he agreed with you, then so did I; I ended up buying it for him. All in all a great purchase as my kids actually wear them without a fight.
