Isn't everything picked up by your eyes emitted light?

No.
Think of it like a cinema projection vs TV screen.
In a cinema a projector sends light onto a screen that bounces off and towards your eyes, this is a reflected light.
If you were to watch a TV of the same size it would be emitting light from LED's shining light directly to you.

Direct or reflected light is just light. Same stuff.
What matters is the content and quality of the light spectrum.
LED lights or even LCD screens can be designed with a more or less healthy spectrum depending on the priorities of the manufacturer. But this is an economical problem that can be regulated.
I'm not ophthalmologist but I do wear glasses for myopia. My concern would be emitted light, distance and emitted heat...
Screens are emitted light. Having a screen strapped to your head emitting light into your eyes is very different to having a monitor in a room (adjusted to ambient light) emitting light and in an environment with a lot of natural reflected light.
Distance, yes there are lenses that bend the emitted light and change the perception of distance to the screen but it's still only a short distance from your face emitting light and heat.
You might be fine for a few years but I would be willing to bet you will have some form of eye issue in later life.
