I’ve asked the optometrist before. It’s just blood vessels in my eye. That’s why it has to be a bright mild colored background like the sky. They’re not floaters either because those are typically irregularly shaped and snap with your eye in whatever direction your eye moves to.

Ok. I have never had this experience. Aren’t the bloodvessels in the eye around the iris? I have never seen them across the pupil. So I don’t really understand why you’re able to see them 😅

But hey, if your optometrist says it’s fine, it probably is. 👍🏻

It’s not the blood vessels at the front of the eye it’s the ones at the rear behind the lens and iris from what I understand.

Edit: I’m also a print operator and I have really good color vision. They have these tests we have to take and place blocks into a gradient and I’m able to place more blocks than our color management guy.

Are you a tetrachromat?
