Is it true that people with bluer eyes process sunlight more inefficiently or sumn?
In: Biology
Blue iris eyes are less effective at blocking glare, people with blue eyes should always use polarized sunglasses outside in the sun. This also might improve performance in low light/night conditions. These effects are small, and the variation in vision from person to person is larger.
Right so.
I was very confident that, the iris being not a part of your eye that is sensitive to light or absorbing light (that’s the retina at the back of the eye), it would have no effect.
Apparently, lighter colored eyes with less pigment seems to actually mean a higher sensitivity to some light. Meaning potentially better vision in dim conditions, but higher sensitivity to sunlight and glare. Go figure. Supposedly the difference isn’t high, but it is present.
I’m blue eyes and my wife is green. Before our LASIK and prk I always needed sunglasses first. After her prk now she needs sunglasses before I do. So real life experience
Generally, brown eyes tend to be better for daytime activities since they’re less sensitive to bright lights but have worse vision during low light environments
Blue eyes are more sensitive to bright lights, which helps during low light environments, but not as good during the day
Green eyes are an in-between the other two, but may skew closer blue eye side
I have light green eyes, they are so sensitive to everything. Wind = tears. Sun = tears. Plain water = tears. I recently made the mistake of opening my eyes underwater in a chlorinated pool a few times and my eyes were swollen shut later that night. I wear sunglasses even on cloudy days. I can’t wear makeup on my waterline because I cry it off immediately. I don’t even wear eye makeup most of the time because it’s a gamble.
When I was little my friend and I would play in my closet and when the lights were off she (blue eyes) could still see things that I (brown eyes) could not see. It would be pitch dark and she could still see things.
If I remember correctly, someone did a study on baseball players and their batting averages during day and night games and eye color. There seemed to be evidence that some eye colors were better suited for night games than day games and vice versa.
Purely anecdotal. I have very dark eyes. My wife and two of my best friends have blue eyes. Compared to them, it’s like I have an anti-glare day-vision superpower. We’ll be outside on a sunny day, or driving in the car, and they’re saying they can’t see a thing, while I can see just fine.
I see a lot of cool interesting answers here. I have sectoral heterochromia. So in both eyes a mix of hazel, dark brown and green. The left is split vertical, the right other has pies of color.
During autumn I can notice colors vastly different from one eye to the other if I close one, then the other.
If I look straight: it blends. if I look hard left, the right eye will un-focus to a point I can’t really see out of it, and visa-versa the other direction.
Likely won’t help to understand here, but thought I’d share how I see things.
Mine were light blue when I was a kid then changed to dark green as I got older.
My daughter’s eyes did the same.
Sunlight sucks, I avoid it.
