Which is worse for your eyes TV or phone?

What would happen if radiation leaks out of monitors?
But really, if these various kinds of radiation did leak out of monitors regularly, you'd likely have people dying all over the place from radiation poisoning or serious cancers.
How far can beta radiation travel?
And, beta radiation can travel a few meters through air.
What is beta radiation?
Beta radiation is comprised of high energy electrons. According to this, "The electron gun inside a television tube could also be considered a source of beta radiation, which is absorbed by the phosphor coating inside the tube to create light.". And, beta radiation can travel a few meters through air.
Can CRTs damage your eyes?
CRTs can damage your eyes. They are shooting electrons directly at them.
Do CRTs have high refresh rates?
Good CRTs can get you really high refresh rates even at higher resolutions which is much easier on the eyes. Either way you're still going to be forking over a good chunk of cash.
Do electrons travel through the air?
Electrons rarely travel through the air unless it's to get to a positive ion.
Do electrons go towards you on a CRT?
No, the electrons definately go towards you and not the side, but the screen absorbs closer to 100% of them, AFAIK. That's how CRT's work though - you have three electron guns encased in lead at the back of your monitor shooting electrons through a screen (Aperture Grille, Shadow Mask, etc.) and then projecting an image on the glass. The thick layer of glass is what keeps the electrons at bay, but it's a pretty unnerving process when you think about it.
Why are CRTs so hard on the eyes?
Unfortunately, most CRTs weren’t good; they suffered from flicker, dot crawl and poor focus, and those were fairly hard on the eyes. Often this was because of poor maintenance, CRTs did not stay perfectly adjusted throughout their lifetime, and sometimes they had to be adjusted in place due to local magnetic fields.
Can a CRT monitor emit X-rays?
A CRT operating at the designed operating voltage will have no harmful X-Ray emission. If the high voltage were to go too high then the tube could produce X-Rays however there are safety circuits in place on all modern CRT monitors that are designed to shut the set down long before Xrays are emitted.
How does the CRT work?
The way the crt works, the light being emitted isn't constant. Most people can see it and it is distracting at low rates. But even at higher refresh rate, your eye can still detect and react to the changes. The eye reacts by opening and closing the iris just a tiny bit each refresh.
What is the human eye used for?
There is one more fact that is not mentioned previously in this thread. Human eye is used to looking at objects that REFLECT light.

Is a CRT good for gaming?

Can CRTs damage your eyesight?
There are two things about CRTs that can potentially damage eyesight. #1 is staring at the same close-range object for hours at a time, causing eyestrain. The muscles that focus the lens are forced to hold one position for a long time, and that can hurt them after too long.
