I have a story about my glasses, so one day I waken up and put my glasses on, but then I gotten more blurry vision, so I told my mom about it and she scheduled an appointment with the optometrist, and after I finished all the tests I was told that my glasses only needed cleaning

Them: What do you see without your glasses? What do I look like? How many fingers am I holding up? What color is my pen? Is your vision dark or dim without glasses?
Me: Ever had your picture taken in blur or not in focus? Yeah it simply looks like that: )

reply

Friend: hey, may I use your glasses?
Me: okay, here
Friend: oh god, how you can see with this thing. Everything is so small
Me: buddy, you are not using my glasses, you're just put that 20cm from your face

I have a friend who's glasses are really thick and I've tried her glasses before. Lemme tell ya everything goes to wack town. Meanwhile she's sitting there not able to see essentially anything clearly.

Q. So, if glasses only correct refraction errors, if you have 'perfect' vision glasses can't improve vision? Or is there no such thing as perfect vision/refraction, so glasses could correct a tiny error?
reply

them: can you take off your glassses for 1 sec person w glasses: ok? takes glasses off them: puts up 2 fingers how much fingers am i hold up person w glasses: 2 them: you dont need glasses

What about me? I can see everything clearly at HD. But when I wear glass, the color got darker and it's full HD.
I can see road light at shining star with many light beam: v

Yeah what about of lack of sense of smell. One thing is to see things clearly but can't tell how good they are until you put them in your mouth. Trust me it's not funny.

Those who wear glasses know the pain of 3d movies. you wear the 3d glasses the movie is blur and if you wear your glasses there is no 3d effect so we wear both
