The worst one is when you wake up having drunk a little bit too much and you can’t find your glasses. You are now effectively blind and helpless and hungover.
Comment on Anon considers LASIK

- I can wake up and glance at the time instead of having to lift something up and put it centimetres from my face to tell the time.
- I can do sports without the glasses falling off, getting mashed into my face, etc.
- I look a lot better, with a -13 prescription, my glasses were heavy and thick
- My nose and ears aren’t in pain from carrying the weight of my glasses all the time.
- I’m not having to constantly adjust my glasses whenever my nose sweats a bit.
- I’m not completely blind any time I have to take off the glasses, like when I take a shower or go in a pool, or especially swim in the ocean where there are big waves.
- I’m not utterly helpless because I’m blind if I lose my glasses. If you’re blind without your glasses, and your glasses aren’t where you expect, you can’t really use your eyesight to find them.
- I don’t have to deal with all the problems of using and potentially losing contacts.

For me, before I got laser surgery, I was once swimming in the ocean at a very big and popular beach. I was wearing contacts because obviously wearing glasses in the water is next to impossible. I got hit by a big wave, tossed around, and lost my contacts. Now I was almost completely blind, in a foreign country where I knew almost nobody, and trying to find my beach towel and bag among thousands of others. I actually can’t remember how I resolved that problem, but I do remember the massive stress and panic being blind like that caused. When I got back from the trip, I got my eyes fixed within a year.

If I was at home, I always knew where I had some backup glasses. But yeah, wake up at a friend’s house or something and you’re screwed.

I once had a friend forget to take out his contacts when drunk. He woke up bleeding from his eyes and struggling to get the things out in severe pain…

Before my wife got the surgery, she used her phones camera to look around. She used to jokingly say that she is a cyborg.
Regarding the topic. For her the procedure was also a game changer.

The answer to almost all of those is contacts.
shneancy@lemmy.world 2 days ago
maybe not in the case of swimming but when you have your phone around you can always turn on your camera and then look at what it’s showing you

If you can find it

Depends on what issue you have, I get intense headaches/nausea/dizziness from looking at digital screens without my glasses for more than 20 seconds or so. The longer I look at them the worse it gets and longer it lasts. So it’s not really viable.
shneancy@lemmy.world 2 days ago
yeah same, but if all you use it for is to scan the room to find your glasses then it works quite well!

i have prescription swimming goggles
merc@sh.itjust.works 2 days ago
Yep, a good idea, but if you use them when playing in the ocean and are hit by a big wave, they can be knocked off.
FiskFisk33@startrek.website 2 days ago
fair enough, when I think about it theyre probably not better than the contacts in that sense

That’s actually awesome, I didn’t know those existed.
KalSeth@lemmy.ca 1 day ago
but you didn’t have any massive stress or panic thinking about the worms that burrow into your eyes after wearing contacts in the ocean?

No, I was on vacation on Earth, not Proxima Centari 6.

Now all I wonder is how the hell you solved that issue.
merc@sh.itjust.works 1 day ago
So do I.
So, what I think happened was that I knew roughly where my stuff was. When I went to play in the waves I basically went straight out from my towel. Because of the rip currents I was being pushed sideways while in the waves, but I mostly kept trying to correct for that so that I didn’t wander too far from my stuff. I am pretty sure about that, because that’s what I always do at the beach. I always hate being pushed around by rip currents and am really worried about getting caught in the undertow so I try to stick to the same part of the beach.
When I got tossed by the huge wave(s) I did end up getting moved sideways. I remember that because I remember how out of control I was. But, I suspect it wasn’t too far. So, when I went to search for my stuff I wasn’t searching the entire beach, just a small section of it.
I think I remembered what colours my beach towel was, so I think I just wandered that section of beach, squinting so I could see a bit better, looking for a towel with roughly the right colours and with nobody on it. Then when I thought I had the right one I crouched down to see if I could recognize the bag I brought.
I don’t think I asked for help, which would have been the smart option. But, I was a shy kid in a foreign country so I am pretty sure I didn’t do that.
But really, I don’t remember. I just have a clear memory of how helpless I felt, and a vague memory of wandering up and down the beach. The rest is just reconstructing how I think it probably happened based on vague memories and what I know about myself.

Not necessarily useful to you any longer, but you can utilize a pinhole lens for situations like that. You can even use your hands/fingers to make the lens. You’ll look fucking ridiculous, but I doubt it’s bother you too much when it’s that or being blind.

To expand on that, you make a very small hole by curling your index finger, and look through that hole.

Just tried this and am now reading comments below to learn what the actual fuck. That works. This random internet advice isn’t a lie.

just tried it and it work?? how

When your eyes are open and unobscured, light is coming in from every direction. The lens is shaped in such a way that light rays parallel to the eye’s axis are focused on the macula, the center of your sharp vision. A near-sighted (myopic) eye focuses those parallel rays in front of the retina, and a far-sighted (hypermetropic) eye focuses them behind. The farther away the ray is from the eye’s axis, the more it is refracted by the lens, and the more obvious its out-of-focus-ness becomes if the lens has an incorrect shape.
Corrective eyewear works by refracting the light before it enters the eye and essentially cancelling out the lens’ imperfections.
A pinhole works by obscuring light rays that are farther from the axis and contribute to the blurry image, only letting through light rays that are near the axis, already aligned more or less with the macula, don’t have to be refracted as sharply, and don’t contribute as much to the blurry image. This is why the camera obscura works, and why apertures in modern photography are used to control both the image’s exposure and the strength of the depth of field.
pitiable_sandwich540@feddit.org 2 days ago
Afaik if you’re myopic, your eyeballs are too long so the plane of focus created by looking at a far away object is no longer on your retina. So i think by looking through a pinhole you widen the depth of field. This means even stuff you don’t focus on is seen sharper.
I wonder if this also works for hyperopia…

I use it to read with hyperopia
vala@lemmy.world 2 days ago
Is this why I can see so much better in VR? Smaller field of view? I always assumed it as kind of a side effect of the depth of field hacks they do but FOV would make sense.
ThatWeirdGuy1001@lemmy.world 2 days ago
I learned this is school. It’s because it focuses the light through a narrow passage which increases the details. It’s also how cameras originally worked.

That has limits. Not sure 2hat it comes down to exactly, but under the most ideal conditions I have pulled off yet I’d estimate it improves sight by 3-4.
-8 with the fov of a pinhole is still blind.
