A cool guide on What different eye conditions look like

44 comments

Oh so that's what blindness looks like
- It’s actually not. This is seeing black, blindness isn’t seeing at all.
  
  But what does that look like?
  
  Nobody really sees black, it's just kinda assumed by the brain because the eyes collect light and darkness is the absense of light.

Wait, eye floaters are not normal?
- I think having them sometimes is normal. Constantly though, not so much.
  
  I have them constantly and this picture looks nothing like them lol
- Ive not had eyefloaters as depicted in this image, but I did manage to get gaslit by people for a long time, telling me I was hallucinating, until I found out that entoptic blue field phenomenon is a thing.
  I was the only person in my friends/family circle who was autistic enough to notice and attempt to describe it.

  That kind of looks like visual snow, which I tried for years to get my eye doctors believe even existed. I know all too well that feeling of being gaslit by assembly line eye doctors just trying to churn out office visits as quickly as possible.
  
  Now I want to look at the sky, but it is covered by clouds today and I'll probably forget when the sky is visible again
  
  Thank you for this. I notice that also sometimes. I thought I just had some mild neurological condition that might be related to high blood pressure.
- Everyone I've asked has them too.
- Floaters are normal, if one were to notice lots of new floaters, or have lots of flashes then they should be checked out by an ophthalmologist.

- no.. at least nott if you you have them permanently

Super glad they added the blindness part. I was really struggling to visualize that one.

I have a partially severed optic nerve and my vision looks like the bottom middle picture if the visible section were replaced with the upper area of y=.5x²

What about astigmatism? Second class eye issue? The balls would look like eggs. Source: all circles I see look like eggs.
- I must have far more minor astigmatisms than you, all I have is difficulty focusing and the massive bright lights at night bloom thing.
- I think you have something else... i also have astigmatism, but circles don't look like eggs, with or without glasses.

  Yeah, that's about right. When I look at the moon, there's a second slightly dimmer moon above it that overlaps by about a third. Lights at night are a cluster fuck; I can't tell a low bed trailer from a standard box trailer. The doubling of the tail lights on a low bed look like the second set of upper lights on a box trailer. I have a hard time focusing in low light. Also, my brain can't render 3D without my glasses.
- My glasses are really thick to make up for my astigmatism, and it makes the world look a bit convex. Eventually, my brain got used to that, but when I switch to contacts I have a good day or two where everything looks concave (first time I thought my phone screen had finally been sat on one too many times) until my brain reverts back. IDK if i've ever noticed circles looking like eggs, but then again I rarely am looking at circles with my naked eyes and maybe my brain is fixing it for me anyway?

That is one mild case of myopia. I think my vision was that good back in like 2nd grade.

What is the difference between cataract and myopia? Is it only me not seeing difference?
- Cataract appears to have a colour tone change and is uniformly blurry. Myopia is not focused on things in the foreground and there's no red tinting.
  Is it possible you have a slight colour vision deficiency? There's quite a high percentage of the population that do.
  
  Hopefully not but yes scheduling an eye exam.
- It looks like with a cataract, the entire image is significantly blurred, whereas with myopia, the blur gets worse the farther away the element of the image is from you.
  Which would make sense, given that the derived definition of myopic is basically being focused on or concerned with only things that directly affect you and not the more grand scheme of things.
  
  Thanks, Maybe I see football and blue/white shirt bit more in focus (only because you mentioned it, I stared long enough lol)
- The cataract also seems to change the colours rather than just blur it out. It has more of a red'ish hue?
  Edit: well not really red. A bit darker?
  
  When it comes to colors I should remember to crank up brightness and turn off night mode (blue filter). Thanks for pointing color difference.
  
  To me it seems brownish, like a mild sepia tone effect.

That is a very informative cool guide indeed, thank you.

Huh, my glaucoma looks more like macular degeneration. I have a fairly sizeable blind spot smack in the center of my left eye because of it.

The „normal vision” one has sky extremely over exposed. Human eyes don’t do that

Nice 👍. I got 5 of these! Where's my price? I'm told I'll be filling most of the block before I die! Except for the diabetic thing.
