Nothing is “injected” lol. Stop using that word that’s not what it means

Which is what shining light onto something does.

I mean while technically it makes sense with that definition, that’s not how most English speakers would use “inject”. You’d probably use “projected onto your eyes” rather than “injected into” in your scenario.

Cuz that definition doesn’t make what he said make sense lol. Light isn’t injected into your eyeball by pressure. Please. Please stop.

Idk what you’re talking about, that’s what I’m saying; you wouldn’t use it that way. My point was that somebody whose new to the language might misunderstand that definition and think it fits in the context.

Here’s another link. Unless you’re disputing Maxwell’s equations you are simply incorrect. https://en.m.wikipedia.org/wiki/Radiation_pressure

Correct. This is the Change of momentum. Nothing is “injecting” light into your eyeballs. The light bounces or absorbs, it doesn’t create the same pressure in a medium.

Yes change in momentum is pressure.

Pressure is defined as force/area which is the same as momentum/area/time.

I agree injecting is not the ideal word but i feel it technically fits the definition.

I've never felt the pressure of light being introduced to my eyes.

Ever.

That’s because it’s such a small amount of pressure it’s impossible to notice.
