why do my eyes change color?

Sorry for the somewhat inappropriate answers you got. Well, what can we do? this world is ful of diverse mindsets you know.\n\nFirst of all, congratulations for getting your question featured on the Yahoo! Homepage. Keep on asking good questions!\n\nNow, to answer your question, some peoples' eye colors change without any apparent reason. As you might be knowing that traits like color of skin, eye (iris) color depend on your genes i.e. these are genetic traits, certain changes in genes might directly affect these outer morphological (=phenotypic) traits. The changes are so slight that they often go unnoticed. Apparently yours got noticed.\n\nBut, if your eyes are suddenly "loosing colors" i.e. are undergoing depigmentation, that "might" be a case of concern. Here is a link where you might get your question answered- http://www.straightdope.com/classics/a971205.html

This is a genetic matter\nIt depends to you mother and father's eye chromosomes\nAt first humans they used to have brown eyes.\nWith mutations in chromosomes, colors like \nblue, green, black, hazel were developed.

I'm not really sure, but from what I understand it to could be some chemical changes in the body based on your feeling and what horomones your brain is releasing. My teacher told me that some teenagers have eyes that change color because of hormonal changes, and when they become adults, their eyes will probably remain one certain color. \n\nIf you are interested in eye genetics here is a link:\nwww.anthro.com/evo/inherit.html\n\nMy eyes are completely brown and my favorite eyes are blue.

you've strained your eye muscles. what have you been looking at? this can also happen during r.e.m. sleep if your dreaming really hard and your eyes are going crazy. watch someone sleep they eyes move around slightly under the lids yours may have went crazy and starting spinning.

Eye color is the pigmentation and reflections of particles in your eye. Basically the lighter the eye the less pigmentation is in that eye.  BLue eyes have less pigmentation than brown eyes. The way that the color is reflected gives the different apperance of the eye color. \nMy eyes are green. They arecool.

There are also, rarely, some people whose eyes appear aqua or violet, as well as the pink-eyed albinos. Eye color is determined by the concentration and distribution of melanin in the iris, which affects how light is reflected by the iris. The limitations on eye color are probably the same as the limitations on skin color, which is all controlled by melanin.\n\nHere's a link to an interesting article on eye color.

I used to get this a lot when I used to regularly stay awake for 70+ hours in a stretch (I had problems and didn't sleep much).  Basically the way that the eyes work involves two main pigments (often called visual yellow and visual purple) which are photosensative (like camera film) and they constantly renew themselves, if you have not slept enough sometimes the production of these visual pigments slows down a bit leading to shapes and specks in th peripheral vision.  \nHave a great day and get more sleep!

it might be serious or might just be tiredness or brain working toomuch! the big problem hope is not could be colour deficiency in the eye theses are a few types of signs. no need to be alarmed. just relax and have a check with ur doctor.\n\ncheers\nGood Question!

I have hazel eyes and they change color anywhere from green, to green-brown, to blue.\n\nAll eye color can change over time because of age or, unfortunately, disease. \n\nEye disease is a cause of color change. So, ask a doctor to examine your eyes if you notice a slow loss of color. The change could be due to Fuch's heterochromic iridocyclitis, Horner's Syndrome, and pigmentary glaucoma, says Brian DeBroff, ophthalmology professor at Yale University. \n\nAging, however, is the usual cause of color change over time. So, yes, Emily. Color can change as we age. It does so for 10 to 15% of the normal Caucasian population. These people's eyes change slowly over many years after they reach adolescence. \n\nHow and why eye color changes - Pigment in the stroma (the connective tissue of the front layer of the iris) gives the iris color. Iris color can lighten if the number of pigment granules in the stroma decreases or if the granules produce lighter pigment. (See figure.) The iris can also lose color if the stroma pigment degrades. \n\nEyes, unlike skin and hair, do not synthesize color pigment continuously. Instead, eyes retain the pigment granules and accumulate them in the iris stroma. So, if the pigment degrades, the eye color lightens.\n\nLikewise, eyes can darken if the number of pigment granules increase or if the granules make darker pigment.\n\nThat's how the color changes. Why does it change? Genetics is the key as experimenters learned by studying twins. They observed the eyes and skin of identical twins and non-identical twins of American Caucasians between the ages of 3 months to 6 years. \n\nBoth sets of twins showed a "darkening with age of both the hair and eye colour," says Sturm. The identical twins changed color together, at essentially the same rate. The non-identical twins changed color but at different rates, which indicates a "strong genetic influence in the timing of these colour changes."\n\nEye color probably changes for the same reason we have one head instead of two: genes. Genes determine all body characteristics — including changing eye color as we age.

If it's getting gray around the outside of the iris (the color part), that is something that normally happens as you age. It's fat deposits, but nothing to worry about. If it's getting cloudy around the pupil, or you are having increased difficulty seeing, go get it checked out soon, there could be a problem.

Pressure on your eyes causes the cones and rods of your retina to fire.  It is just a chemical response and your brain makes sense of it from learned responses.  The colors are dependent on the cone cells that are triggered.

My grandma's eye color changed from green to blue after she got eye surgery.  And my sister's eyes changed from blue to green.  My brother's have changed from light green to light brown.  So, it's common with time.

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!))

The first question would be are you taking any meds? Some meds can cause sensitivity to light. Eyes tear for several reasons... To clear out foreign objects.2 over active tear ducts..3 supply moisture. Try taking an antihistamine. If it is a worry to u you should consult a doctor
