Once I worked with an engineer like this. His eyes were so bad that he was ineligible for laser eye surgery. When he took them off to fix something you could practically hear a "zoom-in" sound effect.
When my dad's coworker took his off he could read microfilm
Damn! Can this person normally see inside their own brain without those things?
gotta go for those extremely high refractive index exotic polymer composite lenses
my glasses get hella fuckin thick when they need to be made of regular glass too >_>;;;
Yes! They're more expensive but so worth it. It not just comfort/appearance, you also see better through thinner plastic. And they're better able to stay in place without falling off and getting scratched.
Btw, the best way to protect your glasses is to keep them on your face. Have a safe container on your nightstand, use museum goo if you worry about it falling off. If you have to put them down, leave the arms open so the lenses stay 90° from the surface, and always put them someplace that's higher than your waist.
Personally I clean mine with less than a drop of dish soap (or liquid hand soap in an emergency) and running water, and once I've gently washed them, I turn the stream low along the edge so it runs off both sides without leaving drops. Then I wipe the frame but not the lenses, only dab any stubborn last drop to remove it. In most cases it's better to put up with some temporary dirt particles until you can clean safely, than to wipe and create permanent scratches.
But they're so expensive...
there are some things in life you don't skimp on, it's either all or nothing.
your toilet paper, your mattress, the power supply for your computer, and any medical device you require to live on a daily basis, for instance.
i will go into debt for my glasses if i have to, because if i'm stuck with them every moment i'm awake, i cannot survive if it's a miserable experience the whole time.
I agree. It just sucks that something so necessary for so many people is outrageously expensive, it just shouldn't be like that.
I must say, a bidet/handheld shower head thingy instead of toilet paper is the way to go. Cheaper and more sustainable
Still need some toilet paper with bidet tho but much much less
That's where the underwear comes in...
Walt you dry yourself with your underwear?
It's female bubbles
What kind of prescription is that she is wearing, +/- 20 or something like that?
They look like Farnsworths glasses.
I want glasses so good that they'd see thru clothing.
My first glasses, when I was a kid and plastics just only came out but not thin yet, were very very thick. These days they're reasonable but still thick compared to other people glasses it seems. Or people seem to think they're very thick, but my brain always goes "wellll not compared to my first set!"
