Blue blockers at work or in public?

    Hey guys,

    What do you say to your colleagues at work and clients/customers if they ask you about your blue blocking glasses or BPI 550 tinted prescription glasses?

    I educate them. If they want to learn I tell them more. IF they mock it I ignore them from that point forward.

    You can buy clear ones that block 99% blue light

    my clear ones are supposed to block blue lite - but they don't.

    we love our new carbon shades ....they seem to be very well made and block a lot more blue lite than our old cheapies from amazon.

    of course - they did cost $300.00 to get them to Oz -ouch! We love the look of them and the last time we wore them in public - no one said a word.

    The clear ones only block very high frequency blue light. If you are talking about Zenni Optical's "blueblockers" they only work for blocking below 450nm if I am not mistaken. This is not very effective for preventing melatonin suppression.

    Zenni blocks high-energy visible (HEV) blue light and provides maximum UV protection.

    This is what they state on their website so does this mean Toby is right - find this very confusing!

    I did ask this a while ago - difference between high & low energy blue light?
    I was looking for some blue blockers on line & found ones that state this -
    blocks 90% of high energy blue light (To provide maximum protection)
    Lets through 70% of low energy blue light (For minimal color distortion)
    Does this mean they are good or not so good?
    Jack answered this - Frequency. anything north of 385 nm is high power blue light. Lower power blue light is 470-500nm
    but I still don't understand whether these are ok or not - anyone help?

    They are too risk to chance because melanopsin receptors operate 435-465nm.

    I just got my first pair of blue blockers from Amazon. They are shaped like a welder's safety glasses. I would love to find "stylish orange glasses." And where do I find the best blockers? I want to give them to my 7 grandchildren for Christmas this year!

    Where did you get/order them? I am looking for the most effective blue blockers for myself and 7 grandchildren! I got a pair from Amazon and I guess they work but them look like welder's safety glasses. Not sure my grandchildren would wear them...

    they also sell a Trifield Meter to test electrical and magnetic fields. Excellent to evaluate and open your eyes to the importance of a safe distance from light sockets , lamps, microwaves, etc in the home....you can see the huge magnetic fields of hairdryers and fans.I use the Acoustimeter for Wi-Fi and Smartmeter Safety evaluations. There is also a meter to test for excess dirty electricity in your home and plugins that diminish that. I can't remember the name of that meter. At one time I thought that I wanted to learn this well enough to advise people on it's safety and how to manipulate their environment to diminish EMF exposure. At that time I was working part time for and Integrative Medicine physician . Then I realized that I didn't know enough about electricity to really do this as a business. Plus you have to tell a lot of people" you just need to move" and people are unwilling to do that or unwilling to spend the money for the shielding. They also have some very interesting books to read.
