do these glasses block blue light?

I bought the Uvex S0360X Ultra-spec 2000 glasses because they were advertized as blue blockers, and they do seem to be effective in improving sleep when worn after 7pm each evening.

I'm not sure, I use them to watch TV at night. I believe they're suppose to b/c that's what the TV projects & can keep you awake at night. They do help me feel sleepier earlier in the evening when I wear them before I go to bed & watch TV.

Yes they do block out blue light very effectively. Really helps to use in evening to aid sleep.

Yes, these completely block blue light. Several of my electronics have a blue power light and it is not visible when wearing these. They're safety glasses and come with certification that they block blue light, like for welders.

Hi Virginia,The packaging does not say so. However, I showed them to my doctor who recommended them and said that they were just like his and he uses them to block blue light. Hope this information helps you to make a decision. Seems to me that the company should provide a better answer to your question. Peace.

No. They will block direct sunlight, but not all of the light. You probably want black out blinds for complete darkness.

Not sure if your asking a question or making a statement but it does prevent a little bit of the blue LED ....but it doesn't seems to work well with cyan LED light blue...

I'm not sure of that answer as I only bought one pair and I don't even remember which number. They have a faint yellow cast to them that blocks the blue computer glare. They work really nice.

Yes. Mine has blue lights around the bottom. You can turn them off as well.

Yes, they do block the sun like blue blockers and the wrap around works well. Definitely worth the purchase at such a great price. Since they are not made by "Blue Blockers", they may not want any legal issues if they advertise them as such.

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.

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.

Yes, there is.However, The glass is greenish, block a lot of lights. The best solution is that use a retrofit led light, it has build in lens.

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.

Evelyn Belinda Willis, thanks for your question. For the iPad 2/3/4 we do not have a RetinaShield screen protector to protect from blue light. So, no this screen protector does not block the blue light. Best, Tech Armor Support

You can order these glasses in any power--including zero--no power at all. Looking through them is like looking through slightly yellow glass, so no, they don't affect your vision at all--except to filter out the blue wavelengths that can damage your eyes.

Well, i do not know whether it really blocks out blue spectrum light, instead i'm sure it protect your eyes somehow...

Hi Lisa, I bought these glasses (Blue Blockers) a few yaers ago, both for myself and for my wife. Thses are designes as unisex and looks good on anyone. Remember, you should have glasses large enough to cover area around eyes to protect from the harmful UV rays of th sun, the skin under the eyes ai especially sensitive and pron to form wrinckles if not prperly protected. I say go ahhead and you will not regret.

i don't have these glasses as they were lost but as far as i remember they were a bit darker on the top. they are nice glasses but they do filter the blue color out so when you look at a green signal it's not as bright.. (not a great thing for us older people)

I am not sure what you are referencing, but it does not block out blue light. Nor does it add a blue hue. If you could clarify your question I would be happy to answer.

If they do , I haven't noticed it. But my eyesight isn't what it used to be..... The only thing I noticed is that incandescent bulbs seem a tad brighter than these . But not enough to make me want to switch back.
