Lol no. That‘s not how glasses work.

Wait, what is that painting? I like it and want to know more/the context.
It’s Plato’s allegory of the cave
Here’s the original art, though I can’t find the original source/artist:
Thank you, The rapy Gary.
'Tis.
Since the light actually passes through the glasses and just gets refracted, there’s no screen in front of your eyes. It’s like looking through water, a window or anything else translucent/transparent.
I think people might have misunderstood what I meant. I didn’t mean there’s an actual projector and screens like in a movie theater. Let me elaborate:
Imagine you’re standing in a room with a light behind you on a ceiling. You’re facing a wall. The light is coming from behind you and bouncing off the wall. What you’re seeing is a projection of the wall into your eyes. You wouldn’t say that you’re looking at the light directly behind you.
Imagine the overhead projector (if you’re at least as old as I am). It doesn’t have any electronics. It’s just a strong light, a lens and a mirror. And it projects the writing on the wall. You’re looking at a projection on the wall in the classroom. You wouldn’t say you’re looking directly at the ink on the transparent piece of plastic used in those projectors.
What if the window you’re looking through was actually a prism that refracts light at a right angle and you’d be seeing stuff that’s actually on the far left side of the house? Would you say you’re looking directly through the window like you would if it was an ordinary window?
You can see this effect on the glasses if you place them on the table and look at them. You won’t see the table cloth underneath the lenses straight through them. They refract the light and you will see an image on them of whataver object they’re pointed at.
That’s what I meant by projection.
Also, in the right conditions you can see through water and a reflection of something on it’s surface at the same time.
In that case, you’d never see anything through anything but a “screen” because of the lens in your eye. (Using the definition of “screen” to be a “barrier”, which in this case provokes a transformation, or projection, of light.)
Yes, but I wear glasses so there’s an additional “screen”. That’s all I was saying. It didn’t occur to me at the time that we all already have lenses in the eye. So I guess me talking about glasses was redundant. I should have made the same post about those lenses. Fuck it. Live and learn …
Doesn’t matter, it’s fun to see how far you can bend definitions (and I did go rather far with that one).
Also, I’m not sure where those down votes are coming from. Showerthoughts don’t need to be fully logical, taking all edge cases into account, etc. After all, it’s just a showerthought to discuss and joke/awe about.
I’m sorry, but I wasn’t downvoting you.
Oh, no no, I was talking about the down votes that you’ve been receiving. My bad!
as someone who needs coke bottles to see properly, i understand how you feel
i would also love to smoke some of the weed you had before posting this
Don’t mix coke and weed.
No, it’s “high, how are you?”
My dad calls them ashtrays.
No, you aren’t.
Prove it!
Either look up how lenses work or go back to your Play-Doh’s cave.
My cave is made of plastecine, thank you very much!
I like your style, Socrates
You’re never looking directly at anything. All you see are images reconstructed by your brain from the input of the two very shitty cameras you have in your head.
No, a lens and a screen are optically quite different.
“screen door slams, Mary 's dress sways.”
All the snarky well-actuallys on an unserious community really make me want to browse Lemmy more
I know, they’re great, aren’t they? 😛 Sorry if I came off snarky.
For the record you weren’t the one I was criticizing
