These work and fit as expected. There is a yellow tint to the lenses, however it didn’t bother my son.Fit perfect to kidsThe glasses are a little too small for the bridge of my son’s nose, he’s 12 yrs old. The box the glasses came in were smashed So when we opened the box, the pair of frames were crooked. I tried my best to straighten them, but it didn’t help much. My son wears them for online schooling. He said they his eyes feel less tired and I noticed his eyes are no longer red.I wear blue light blocking glasses during the evening when I use my phone or tablet. My daughter has noticed that and asked for a pair to wear herself. I ordered these kids ones so they fit her well and they do. She wears them if she is watching a show in the evening so it protects her eyes and doesn’t interfere with her sleep schedule. I have actually noticed a big difference in her responding to preparing for bedtime with her not fighting it so much when she uses them.My son and daughter been wearing theirs all summer since they have more screen time than usual due to COVID-19. And now 2 weeks into virtual learning and these glasses helps a lot. The only complaint I have from them is that they do give a green tint to everything but the kids aren’t blinking or complaining about eye strain as above.I love the look of these. I am am a small adult but they fit perfectly and don’t look too big in my face. My only concern is I don’t feel that they do much in terms of comfort for my eyes. Maybe it’s just me but my eyes feel dried out and my head hurts while wearing them. I cannot wear them for long durations of time. I am a virtual teacher so this was disappointing. However I do like them to change up my look every once in a while.When, I seen these glasses I thought this would be a good item to buy for my granddaughter to wear when using the computer and her tablet. She’s, eight years old. An, she was all smiles to have gotten them. An, I was glad that I seen the glasses for my grandchildren to while on the computer and their tablets. Sincerely, D.L.B...I got them for my 3yr old. They are a bit big but she can still fit them with room to grow. They work really good, durable so far and lightweight.
