One group from Australia (lots of studying and reading of things close by) and another group from somewhere in central Asia (much less time spend indoors studying or reading). Which compared the rates of nearsightedness and found no correlation.

    ~ flips tables ~ there is a huge difference between energy density and energy amount.
    Smaller wave lengths have features like more flips of polarization in a given spacial region, and they effect atoms/have deeper penetration.
    It is like saying a a pound of lead has more energy falling than a pound of feathers because we see the lead do more damage. A pound a force at x speed is that force, regardless of it's size.
    100 watts of red and a 100 watts of blue are the same power with vastly different reactions and spacial flux densities.

And allows humans to use screen time for so long let's say about 10 hours and still didn't even experience any blindness or eyes to hurt, not even causing blurred vision...

    One observation to be made: damages due to energy deposits in materials are not proportional to energy of incoming photons, in special mode there are threshold effects which may come into play. Below such thresholds even increasing the intensity of the illumination would not permit specific reactions. Said otherwise certain chemical reactions may not be able to take place at energy E but at may at energy E' (where E'>E) and above. It is true that once the minimal (or the proper) photon energy is available, the intensity of light gives proportionality to damages which may occur.

    One point that's being ignored is the background intensity. It's bright outside, so when you stare at the sky, your pupils constrict to reduce the incoming light. When you're staring at your phone at 2am in a dark room, your pupils let in more light, which is furthermore concentrated at the center of your vision.
    I read about something similar a few months ago, but couldn't figure out the frequency distribution of the blue in typical screens. I've heard a few claim that it's not far from the 449nm, but this is a case where details matter.

    two possible reasons why the test in animals showed damage was probably due to mice being somewhat nocturnal otherwise if the tests they were performing were only using the cells that specifically detect light but not using all of the cells that make up the eye itself, it's possible that the unsheltered ocular cells were more susceptible to damage from light. without the rest of the eye there. It is also plausible that it was some combination of the two factors as well.

    Okay, so coming from an Optician, you people need to know 4. things. 1: The blue light that we are talking about is (mostly) not in the visible blue light spectrum (The video is kinda misleading/inaccurate to that point.) 2: Yes, most of our exposure to blue light is via the sun, which is why your optician tells you to wear you blue-light blocking lenses all the time, and not just in front of your compy. 3: I personally own lenses with and without the blue light blocking technology. My eyes experience much less strain when I use my blue-blocking lenses. That's really all I need to tell myself and my patients that it's something worth taking seriously. 4: Your eyes are relaxed when you are viewing something far away, but they constrict when you view things up close; ask your far-sighted friends- this means bad headaches after a while. The whole "Take a 20 minute break from your screen" thing will save your life.
