MadSci Network: Anatomy |
Hello Fi, (I first wrote Hi Fi :-) I think I can answer that, not because it is within my field of knowledge (biochemistry), but because the same thing has been noticed with my eyes. They are usually a grey-blue but sometimes take on a noticeable green tone. If you look closely at the iris you will notice that it is very, very wrinkled and has many shades of colour. Depending on the intensity of the ambiant light, but also on mood, it will either contract, making the pupil smaller, or relax, making the pupil larger. In my case, it is with dillated (larger) pupils that my eyes turn green. I’ve now observed this in detail in a mirror: when the iris changes in degree of contraction, the wrinkles either open up or close, displaying slightly different colours. In some people it’s probably more noticeable than in others. Can this be what is happening with your boyfriends eyes? Kind regards, Erik admin note: I think "sectors" might be a more accurate term than "wrinkles", but this is a good explanation. Erin
