BLACKOUT open thread!

Okay, we're talking apples and oranges here. I never said that blinking and squinting were logical solutions. I stated that they ARE the defense mechanisms that light sensitive people employ. George isn't wrong, they aren't practical solution. That was never my point. I was stating that regardless, those ARE the solutions that photophobic people employ unless she's trained herself to not do those things. And even then I still don't think it's something that can be completely gotten away from because, well, it's uncomfortable and painful.

I think my curiosity and confusion about retinal KA is because I'm trying to understand the light sensitivity coupled with the better night vision. Night vision is based on the rods, which is why it's harder to differentiate colors when there isn't good light and why that 100 watt bulb essentially blinds you. Rods saturate at high light levels and they don't filter color vision. It's also your cones that give you that crisp clarity to your vision, which you lack as light levels drop off not so much because of the lack of light but because the part of your eye responsible for it isn't working any more.

Is my confusion a bit more understandable now?
