That's also why certain contact lenses can't be worn overnight or for long periods of time because they aren't as breathable. At least that's what my eye doctor said when I got them.

Yep and if you wear them for too long your body will grow new blood vessels to supply your oxygen-starved eyes with what they need. These new blood vessels can cover your retina and can lead to blindness.

Learned that one by sleeping in daily disposable contacts for a while and losing a significant portion of my peripheral vision.

Kind of. This happened to me. My vision was noticeably bad when I was diagnosed with it, but once I started taking care of my eyes, they blood vessels shriveled and shrank, and my vision mostly improved to the point where I didn't notice it anymore.

100% recovered, no. But better.

Oh damn, did not know that was a risk

That's correct. It's generally recommended for lenses to have at least over 100 Dk/t for sleep and they need to be approved for that. Dk/t is the measured oxygen transmission through the lens material, the higher, the better. I would not recommend lenses with Dk/t of 30 and under even for daily wear as they starve eyes of oxygen. Especially since there are very affordable ones with very high Dk/t like Miru and Biofinity (around 160 iirc).
