Who is watching it in blue light filter


Me

[anicetoogumoro]

I've been binge watching videos and doing a lot of surfing the net on my laptop for over a week, and I've noticed having more headaches, my sleeping pattern being thrown off, and even blurred vision at times (never had this problem before in my life). I just turned Iris on on my laptop today and I already feel my eyes are more relaxed. Oh and Julie, my eyes are recovering even faster now thanks in part to the light I see, becoming beautified by simply bouncing off of you, before reflecting into my eyes, massaging them all the way into my brain. Ok, I need to sleep now.

More time in front of screens = more blue light = more headaches & fatigue = lower productivity.

The thing is, this is on something that makes blue light.

It’s because you’re not blinking enough and you’re focusing to a close source of light for hours.

I had serious trouble keeping a steady circadian rhythm (sleep), because I spend so much time working with computers in my studio.
After switching to night light, and just drinking some more water and getting some vitamins in on a regular basis, my sleeping works like clockwork and I'm so much better off for it. It literally feels like I've regained at least 10% of my brain functionality.

I highly recommend that more people struggling with this consider switching these things up a bit -- going to bed at 6 am and eventually winding up getting out of bed at 11 pm is seriously harmful in the long run.

Best of luck!

Being an SJS survivor opening my eye is like tearng open a fresh wound. Thus am current on this topic.
BLUE LIGHT TRIGGERS A SELF DESTRUCT MECHANISM IN THE RETINA. IRREVERSIBLE.

Strange. I have been using computer since I was a kid and not just using. i am addicted to games. I am 24 years old now. Can anyone explain why my eyes are still clear and no damage?

Are either of these girls single? I need to take one of them to their favourite restaurant and talk about blue light

[sarcasticcats]

What will you guys do about the sky? It's all blue and high energy???

[josephfernandez]

I realized that, from the very first seconds, that we, as an audience, were doomed...

[thetheoreticalnerd]

You do realize that the blue light of the sky is much more intense than that of a computer screen, right?

[okay]

my eyes are rekt from all my blue lasers i play with probably not my computer's led monitor.

Well this video was just extraodinarily *BRILLIANT* tell us how dangerous 380-400nm light is while simultaneously exposing our eyes to a neon blue screen.

[lemaggerooty]

I think that blue light also keeps us awake as does the daylight which we percept as blue
