Do these block blue light? Some people say they do and some say they don't.

I am sorry. I don't know if they specifically block blue light. I use them only when on the computer. I was experiencing pretty significant eye strain before getting the glasses. Now it is almost non-existent. I continue to be very pleased with these glasses for computer use. Sorry to not be able to answer regarding blocking blue light.

The lights don't however I just leave them on. They are blue and look nice on.

I switch mine to the blue at night and they are just fine. The white light is pretty bright.

No, they are not the blue-type lighting but they give off minimal light. I thought they'd give me more work light but I'm very disappointed.

Kinda. Not great. What I love most about these, is the way they block glare but don't darken everything

They block enough not to see through but if there's a full moon light gets through. They aren't black out so if the spot light is close I'd probably say no.

I bought them to block out blue light from my computer and e-reader. They aren't tinted so I wouldn't recommend them as sunglasses.

I use them for night and rainy driving, and I think they're very good at brightening things up. I don't know if they block blue light completely, because I haven't anything to compare to. I just know they work for me and I have a pair in each vehicle.

The manufacturer dose not want to make that claim. The blue light blocking claim would be more for medical devices witch would be more expensive than these glasses.

It will block UV but I don't know about blue light. You cut it to fit screen.

There's a setting for them to blink on and off, or they can be on or off. They shine but don't "twinkle."

Mine were fine when I got them. I really like them. They give a low light at night-not a glare to the eyes.

My grown son and grown daughter both think that they're bright enough. They are definitely not like those blue lights that blind everybody in their eyes at night, which we all hate!

I dont know. they appear to block some blues. I wear them for driving on overcast low light days.

It's decent with the blue light blocking, not the best. In hindsight I should have ponied up and bought the more expensive ones since I am on the computer about 12 hours a day. The sleep factor, I'm unsure as I didn't put emphasis on that when I bought them nor have I tracked it. I hope this helps.

No, the blue tint on the bulbs are used to filter out the yellow from standard halogen bulbs. They instead emit a bright, white color.

My sleep doctor told me to wear blue filtering glasses to help me sleep. He said to wear them at night when on the computer or watching TV because the blue light tricks your body into thinking it's daytime and produces hormones to keep you awake. By the way, I am looking. I haven't bought any yet so I appreciate reading your reviews. Thanks!
