It wirks well, I'm not sure about the UV rays but driving into the sun it is great.

Couldn't tell. View is distorted. Cuts sun glare a little. Not worth buying. Mine also broke while trying to get it rotated down.

It lets light in and blocks vision (you can't see in or out), but I don't know about UV rays. Very much like stained glass, just lots easier and cheaper.

They are silver on both sides, but they are not see through and do block the sun very well. I also have a set of black, those block more sun; but somehow hotter, bc of the color. Hope that helps.

I do not know what blue light is. I use them to reduce glare from car headlights and when driving in rsin or strong sunlight.

If you're talking about electricity...no.If you're talking about magnification...no.These glasses only filter out the harsh blue spectrum of light. They also create a small pocket still air around your eye, helping with dryness due to dust or wind.

These are not like Blu Blockers. They are a very pale yellow tint that is great for staring at computers if you still need to view colors accurately, but Blu Blockers have a dark amber tint that cancels out more blue light (orange cancels out blue better than yellow because orange is complementary to blue) and provides enough tint to shade bright, outdoor light.

Yes, but you have to cover everything with a towel to block the UV light inside.

These are indeed not suitable for driving as they almost fully block blue light! These are primarily protective glasses and they provide good "physical" protection against anything that can get into your eyes (e.g. in a lab or manufacturing area). The secondary 'property' of these specific pair with orange lens is to block blue light. In certain industrial environments continuous and/or high level of blue light is present which can cause damage to, or at least fatigue of the eyes. So, the blue blocking property helps to mitigate that for the workers. Now, most of the consumers here (me as well) are buying these for their blue blocking capability and not the physical protection. Generally, the blue (and green to some extent) light is one of the causes of eye fatigue for individuals who work in artificial light (e.g. fluorescent), and with computers (the monitor being the source); therefore, some people are getting the glasses for helping with that. Another interesting advantage of wearing these is for those people like me who have delayed sleep phase syndrome: it has been found that these individuals can benefit from reduced blue light, a few hours before sleep. By reducing the blue light with these glasses, the amount of disturbance to the sleep is reduced - at least it is working for me. - For reference on the protective property of the glasses please visit "http://uvex.us/uploadedFiles/ProductConfiguration/ProductLiterature/skyperfamily.pdf" - For reference on the lens tint property please visit "http://www.uvex.us/uvexlenstechnology.aspx?id=4178" - For delayed sleep phase syndrome and the effect of blue light please check: http://en.wikipedia.org/wiki/Delayed_sleep_phase_disorder#Non-pharmacologic Cheers, hhsquall

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.

You CANNOT see the UV light. When the UV light is engaged, there is a bright blue indicator light. However, this is not the UV light. The blue indicator light will not damage your eyes or skin. The actual UV lightbulb is mostly protected from exposure inside the filter's housing. I believe the warning in the instructions refers to viewing the light when the purifier is disassembled.

No. These cut down peripheral glare but they seem to intensify light sources such as oncoming headlights. At least that is my experience. Perhaps a different owner has had better results with night glare.

Sorry I can't help, I never use them, I have indirect lighting in the rooms I use my monitors in.Good luck, I know there are some nice filters out there, co-workers of mine have had them in the past.

They will cling to the screen but the light shines through. I didn't try it over blue light but I putt it over the computer screen and it doesn't block out the light.

The front panel light is brilliant blue, almost enough to be called a piercing blue light. This is not the UV light though. I find the blue distracting but then that is only until I lie down and put my sleep mask over my eyes. As someone else mentioned, you can tape over the blue light easily if you want to.

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.
