    A few days back someone dropped a video about blue spectrum light canceling glasses. They were called BluBlox and sold for north of $100 bucks.

    I had noticed how using the computer a lot was causing my my vision to get worse, fuzzy and blurred. I was in Sam's Club and asked the optician about it. He said that what the blue spectrum, in excess, is to cause inflammation of the optic nerve at the base of the skull, where it enters the nerve center. They had some (blue blocking glasses) there for $25, and since theyre returnable I bought a pair.

    Been using them for 4-5 days now and WOW, my vision is coming back to normal.

    So are they like sunglasses? I've heard of them before and also stare at screens for my job. I'm going to check them out next time I am at Costco. Thanks for the tip

    No, they are clear just like regular glasses without magnification.

    The biggest issue with blue light is that it doesn't focus properly within the eye (different wavelengths refract differently; blue ends up focusing just in front of the retina, as if you were nearsighted).

    Probably not a big deal in the natural world and also not a problem with incandescent lighting, but "daylight white" LEDs tend emit a lot of blue (white LEDs are a fancy yellow phosphor deposited over a blue emitter). So, yeah, filtering out some blue isn't a terrible idea.

    As a related side note, anyone who selects blue backlighting for automotive interiors & IPs needs to be demoted to a job where they won't hurt anyone (like, Idunno, picking out anodization colors for Q).

    Hmmm i always thought the eye strain came from the refresh rate 30-60hz. Not necessarily any color. With blue light only really affecting sleep patterns, why notebooks and cellphones have a “night mode” that warms the image up a bit, reducing the emission of blue light.
    Edit: not disagreeing just loudly pondering.

    Refresh rate is a completely different issue. The blue light problem is simple physics.

    Those of us with corrective lenses get a double dose of this problem (the corrective lens introduces additional focus issues), and then astigmatism is a real kick in the crotch.

    Thats the other thing I forgot, it definitely fucks with your sleep pattern.

    For someone that doesn't need correction, I highly recommend Gunnar Optiks. I used to get wicked headaches and blurred vision for a couple hours after the workday until I made the correlation- blue light and fine text on an LCD screen.

    Well made, durable, and not too expensive. The computer ones are made to provide about 1.25x mag at 36", not the same as the 18" used for reading glasses.
    Edit: For those of us old fucks that need glasses now, pay the extra $45 for the blue light-blocking coating. Totally worth it.

    No wonder my nuts hurt every time I get eye strain headaches.

    With regards to these things,,, do any of ya'll have bad 'night' vision? Do these things help with that at all? My Lady has taken to using her "night vision goggles' when driving. (that's what we call the 'yellow safety glasses') just so that she can see better.

    My NV is ok but I might try these while driving to see if it helps with the glare of the new bluish headlights which are really fucking annoying.

    I wear yellow-tinted glasses when riding mountain bikes at night. They give me pretty good night vision. Or maybe it's the 5500 lumen light setup I run on the bars and helmet. Nah, it's probably the glasses.

    There is potentially some benefit to using polarized lenses at night, particular for those who suffer astigmatism.

    You dont need glasses to ignore it but I think the outcome will be the same.

    All you guys are colorist! Blue Colors Matter!

    It's my favorite color and things don't look right with the blue turned down. It's annoying.

    There are also apps you can download onto your phone that limit/block blue light from the screen. Especially helpful when surfing the web in unlit rooms etc.
