Causes Eye Color Change
The darkness of: Skin around the eyes that comes from bruising is eventually absorbed back into the body.
Sunlight: Although it is not typical some people have light sensitive freckles on their iris that can darken with cumulative light exposure. Since eye color is a composite effect this is one possibility. Another is a condition called Fuchs Cyclitis which often makes one eye duller or heterochromic to the other. Both possibilities should be investigated by an Eye MD.See 2 more doctor answers
A few conditions: Generally, eye color becomes "locked in" by about 6 months to 1 year of age. The iris contains brown pigment, and the less pigment present, the lighter the eye color becomes. Diseases that damage the iris (inflammation, certain glaucomas...) can lighten it while tumors and freckles can darken parts. High corneal cholesterol can make the eye seem bluer. Any changes in eye color should be evaluated.See 1 more doctor answer
No: Not sure what you mean, but it would be crazy to put acid your eye. Are you talking about ingesting acidic substances? That wouldn't change eye color either.
The part of penis head become much darker (closer to the urethra). I feel no other causes for concern except color change. But it lasts for a month…
Many Possibilities: But most likely normal. The tip may have gotten irritated causing some darking in the healing skin. Irritation could be from sex, masturbation, rubbing on clothing, skin infections... It could also be dye transfer from clothing. If it continues or has other symptoms, have your doctor look at it.
Medication?: Eye color rarely changes if ever. Sometimes it can be from medication such as a prostagladin. Tumor can also get the eye color to changes. You should see your primary care doctor you might refer you to an ophthalmologist.
Arcus sinalis: All of us as we get old near the limbus (edge of the cornea) over the clear part of our eye, we get deposits that make the clear part turn white. That makes our iris color less obvious and pale. Also as we get old our iris atrophy and gets thinner with less pigment on it.See 1 more doctor answer
Very little: After the adult color comes in at around age 2, the color is generally very stable from that point on. The color can be altered by certain diseases of the eye interior, a few pharmacologic agents and cornea conditions which mask the iris color. If you think this is happening see your ophthalmologist.
Corneal changes: The iris of the eye which is the structure which gives the colors we usually attribute to the eyes (blue, brown, hazel, etc.), cannot change even when diseased. If you notice a change in the color it is probably some change in the cornea which can develop deposits making it whitish which blends in with the iris color. If this is a rapid change, check with your ophthalmologist for understanding.

No real change...: In general, eye color does not change other than in newborns. However certain eye conditions can give this appearance and should be looked into by an eye doctor. In addition, sometimes hazel colored eyes can give the illusion of looking more blue, green or brown depending on what color clothing surrounds them.
The first year: By 6-12 months of age, a baby's iris has reached its final color. There are those who may go a little longer, and those with hazel eyes can appear to change between brown and green, but generally, the pigmentation has reached its full level by the first year.See 1 more doctor answer
Not likely: It is possible that your eyes seem lighter because of the clothes or make up you wear. They are not actually lighter. There are a few medications that make the eyes darker as a side effect. There are none that make them lighter.
Light direction: Pupils normally look dark, as the direct light path would in fact be from behind your head, which blocks that. Cameras with a light source closely aligned to the lens, can cause the red eye which is in fact the natural color of the back of the eye. Lighter, larger pupils are more prone to this. To eliminate this if you take pictures is tell the subject to look at your shoulder.
