How is it that sometimes, when I look in mirrors, my eyes change colors?

Your eyes aren't actually changing colors. What colors you're wearing, the lighting, even the colors around can affect how you perceive things. Like when people say things like, "Oh wow, that color really brings out your eyes!" What that means is that whatever color they're talking about makes it look as though your eyes are brighter, even though they aren't actually brighter.

There are two reasons.\nFirst, there is a choroid layer that has a black color pigment on it.\nSecondly, the light entering the eye through the pupil is not reflected. if no light is reflected then from your prespective,(assump you are looking into the eye of somebody else), the light that enters the other persons eye does not reflect back and enter your eye and initiate an action potential in the rods or cones on the retina, so what you see is a black colour.

On one can tell lighting is different every time.\nJust like it does not hit the same place two times in a row.

I feel its the opposite. Because every object absorbs all colours in the white light and reflects only a particular colour which is seen by your eyes. Now there are many times where the eye can be fooled like the forward mails you would have seen (optical illusion ones).\n\nIf something is Blue its actually the opposite of blue, that is, all other colours mixed but blue ;) \n\nIf something looks black, its merely not capable of reflection, so you dont know what its colour is...\n\nhehehehehehe wierd theory right?

I don't know but mine do the same thing. Mine are dark green most of the time with a brown ring around my iris. Sometimes a little more brown comes out(more hazel). I find that it depends alot on what color I wear or what kind of a mood I'm in. Strange really.

That is normal for your eye to do so every once in a while, so I wouldn't worry about it. I think it is funny every time my eye does, it feel funny and weird.

I don't know what an "unnatural color" is ... but if your eye color is different from everyone else's, it  sounds cool.  When people ask, just smile and say you are special.  (You are!)

All colors...or clear.\n\n\nTechnically, there's no true color.  The backing surface, behind the glass part, is a reflective silver-esque color, but it reflects light perfectly, which makes the person believe that it has all color properties.  Howevever, since light holds a wide array of colors, the mirror is simply reflecting all colors.  But since it requires light to show color, and it doesn't stay static in it's color reflection, it doesn't exactly have any one color.

I have some little dots in my eye, and my eyes change shades of colour depending on my mood.  Weird eh?  But like you the eye doc said I have excellent eyesight, mind you I knew that when I read the bottom line without squinting and he looked at me with his mouth agap.  I say don't fret it.

wow, what a cool way of thinking!  I have wondered sometimes that when I walk up to a mirror and then walk away, where does my mirrior image go?  Does it go do something else until I summon it to the mirror again?

That's because light reflects in the mirror just as if it's coming from the same distance the real object is but behind the mirror.  You are nor looking an image that is at the mirror distance, but really at the real object distance.

my friends used to say my eyes were orange, but they are just light brown as well.  Maybe we are unique and have a new eye colour?

First of all, eye color can change with age. Second, it's more complicated that the simple brown / blue description that they give in high school biology class. So I suspect that the answer is yes.

This could happen one of two ways:\n\n1) The mirror is made of another material than glass or the usual material used.\n\nOR\n\n2) The mirror has curvatures somewhere along the way creating a distorted image.\n\nHope this helps!

I have a green eye. Sometimes it goes blueish, but it's hardly ever brown. I have another one that's just like it!\n((Guess Malibu wins this one!))
