When you make claims and people ask you to back up those claims, it is reasonable for you to do so. Expecting other people to do the work to back up the claims you are making is not really the ethos of this forum.

If you are asked for sources and are unwilling or unable to provide them, people will (rightly) ignore your claims.

I'm fine with not answering questions about basic things, thanks.

Most of the research I've read around this subject seems to indicate that the important thing is getting actual sunlight exposure for eye health. It is not entirely clear if this is related to the broad spectrum nature of the light, the intensity of the light, or other confounding factors.

You seem to be claiming that light which comes from screens is inherently bad for your vision, which is a very different thing, and which I have not seen credibly evidenced before.

So yes, you might want to do a little more reading about "basic things", or consider sharing the things you're reading with the rest of us.

Computers have been around for 40 years. TVs even longer.

We would know pretty definitively if they degraded your eyes.

Do you have some evidence we are all missing out on ?

Fine. Shining lights in your eyes improves vision.

Your eyes are always receiving light, that's how they work. It's not at all obvious to me why an LCD backlight would be different from sunlight or an incandescent light or any other light source.
