Will this block out blue spectrum light (with all of the accompanying health benefits by wearing them at night)?

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

It will reduce the glare but it won't block it out. If it were for a room I would be sleeping in, I want it dark so this alone would not work.

Yes, I believe it will. They recommend you use it near your workstation or where you sit to read. Many, many people wear glasses or contacts to do both. I think the light has beneficial effects through the eyes and the skin just like the sunshine outdoors. Not a doctor and this is only my opinion.

I wear mine primarily at night with no problems. The product adjusts to give a comfortable fit. I am very happy with this product.

Yes, it helps. It's good, too, when night road crews use krieg lights to work. I wouldn't say it's amazing, but it's like sunglasses. I bought this product two years ago and I have seen a similar product on TV promising more in the glare-blocking department. So do your homework. This is a good product; there may be better. (On the other hand, there may be more hype on other brands. This is solidly made and pretty good.)

The screens are translucent -- so if you have bright light, it will diffuse the light but not completely block the sunlight. I think it should work as a good block to keep the strong sunlight from "sunbleaching" fabric etc.

You would have to ask the manufacturer. They claim to block the UV rays but I am no expert and certainly not the right person to answer this for you. I would hope that they were not falsely advertising that feature, but I am going to assume at the very least that they help regardless.

It does reduce visibility at night, does not eliminate. My blinds are down at night anyway, so it makes little difference to me

This will definitely block people on the outside from seeing in the window, while allow you to see them at the same time. It will block some of the sunlight though during the daytime hours. However, when it is dark outside and you have a light on inside, the privacy you have is not as good.

They do a really good job of blocking out light. They also do well at not touching my eyes while I'm sleeping either so I think it might work well for you too.

A little, but it really helps to block out the light. My husband wears ear plugs as well as the mask and he says that he sleeps very well. It does cover the ears, but I wouldn't count on it blocking out all noises. It definitely keeps out light and is great if a person has to sleep during the day!

This is not recommended for night driving although it would work. The chance of cutting out something you need to see is rather great, it would seem to me. I use night vision sunglasses to cut down on glare and they work much better. Either the yellow or the light brown work well. GMM

Yes, noticeable difference at night. The glare of bright lights is diminished, however, it also mutes darkness. I agree with others that its more difficult to see people, animals, or objects on or along side of road. For me, these work best driving towards bright sunlight.

From the computer yes (check out my review). I use them daily now when I'm just sitting and browsing or playing, they take a lot of the strain away and make it easier to go to sleep. They block solar rays, but they aren't really sunglasses, it will still be bright, but the danger from the rays will be gone.

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.

Yes they are not tinted at night.like wearing non prescription glasses. No real advantage or disadvantage

Truthfully, have not noticed if it does, but would like to hear from others if the experience has been different. As to their effectiveness during the day and night time, no problem during daylight, but at night time a strong source of lighting is needed for the ones that I have if you want to be able to see anything. There may have been an improvement (?) after the ones that I purchased.
