The human eye has three different photo sensitive cells, one of which only produces black and white image for low light conditions.
My family, myself included, has an history of some individuals being highly sensitive to bright light - to the point of being painful - but by contrast we enjoy a very sharp night/low light condition vision, to the point we can actually discern more detail under such conditions. There were some very talented night time hunters in my family.
It's not eye or brain hacking just differently adjusted image acquisition hardware.
Does your family have light-colored eyes? Lighter eye colors tend to correlate with better night vision and increased light sensitivity.
No. Basic color is brown and some of us have a lighter shade of brown, slightly yellowish.
My eyes tend to grow lighter towards a green hue when it rains or heavy fogs form and set.
One grandmother used to say we had wolf eyes.
Do any of you sneeze when looking at bright lights?
Not to my knowledge. I personally am not affected.
My family have a thing for bright lights, we don't like them usually, and they trigger sneezing. No idea why.
I'm like you. Bright lights - including daylight without really dark sunglasses - are painful but in low light conditions I can operate far better than the average person.
I don't know if anyone had this in my family before me, but I strongly suspect that my kids have inherited it from me. They are quite young, but we'll see.
You get the odd reaction when everyone complains it's too dark to do something and you reply it's just fine?
More often than you'd think.
When I lived alone while studying, I usually kept only a tiny kitchen worklight on. My friends were always baffled by this when they came to visit.
Once my co-worker asked to borrow my favourite sunglasses. When she put them on, she was still for a moment and then went "MY DEAR GOD, HOW CAN YOU SEE ANYTHING WITH THESE ON?"
The only sunglasses that make sunny days outside enjoyable for me. And yes, they are very dark.
I learned how to handle sun light but I can relate with that so well.
Three different cells? Cones, rods and?
Intrinsically photosensitive retinal ganglion cell
That's a mouth full.
