A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

We tend to describe the pupil as though it's its own actual separate part of the eye. It's almost strange to think about the fact that in reality it's just a hole in the Iris and not a "thing" at all. (lemmy.ca)

For example, why do we say "Your pupils are dilated". They aren't. It's the iris aperture that is dilated.

I'd say it's more than just a hole. I had an eye injury when I was a teenager that caused a detached iris. I didn't have a massive pupil, I had 2 small, irregularly shaped pupils. After surgery, I now have a permanently dilated pupil shaped like a teardrop

Out of curiosity, does a different shaped pupil change your vision? I equate a pupil to a camera lens aperture; the smaller it gets, the less light gets through. Have you noticed a difference?

Well after all these years I've gotten used to it, but my vision is very blurry in that eye. There's also injury to the macula so there's a giant gray spot in my near vision. It's kinda like a giant peripheral vision, but I'm also more sensitive to big changes in brightness
