Human Biology- Human eyes changing color?

Asked Apr 6, 2009, 09:20 AM — 22 Answers
Can human eyes change color, or is it just different types of light reflecting in their eyes? I am dating someone whose eyes are sometimes very blue, but sometimes green. I also have a friend whose eyes change from brown to green.

It's just the light.

Babies are born with blue eyes, which change to their adult color in the first few months. And people with brown eyes may accumulate dots and specks of green and gold over the years so that their eyes become hazel. So yes, human eyes can change color a little bit, not much. But that is not happening with the person you are dating.

I then suppose that the person and your friend you're dating wears contact lenses... And changed them between the times you saw them. Except if you haven't seen your friend for a long time.

My eyes do the blue / green thing depending on what I'm wearing and my mood. I've actually been held down and had different shirts draped over me by friends so that the light, nor my position change while they watch the change happen. It takes a couple of seconds, but it does happen. I have no explanation, be it a trick of the light or whatever it's just kind of cool that my eyes seem to change like that.

Mine do this sometimes - I always assumed it was to do with blood flow. I could be completely wrong though

Reflected light affects apparent eye color. So if you are wearing one color, your eyes will look greenish, another color, more blue. Also, the light around you.

Try walking into a white room wearing a red shirt and you'll see a pink glow. Now go in with a blue shirt, the pink is gone and you may notice bluish or greenish light on the walls, depending on the light source. Sunlight is yellow. Artificial lights are different colors.

I'd be very surprised if mood affected eye color. On the other hand, if your pupils dilate and contract with exposure to bright light or dim light (and to a lesser extent with mood), that could alter the color of the iris to a degree.

My eyes changes to green, brown, blue, and really dark blue. Is that normal for eye changes? I'm not wearing contacts and they only change eith my moods.
