Has Modern science made it possible to permanently change your eye color?

I don't think so. But firstly you have to think again about why people want to change their eye color. People in Asia like to wear blue/grey tinted contact-lenses because they think that deep brown eye is not cool. Otherwise, people in Europe or somewhere else want to have deep brown eye because they think that their blue/grey eyes are not sexy. What a very complicated thing to change!

Although I do not suggest doing so, latanoprost (Xalatan) is a prostaglandin medication used for glaucoma, that, with extended usage, will increase iris pigmentation. This is a side effect or adverse reaction upon using lantanoprost for an extended period of time. It is a marked event for those who have blue or green eyes, as their iris is permanently changed to brown. While there is no damage to the eye associated with the color change, some people do not like this cosmetic change. Again, use of this medication is solely for glaucoma, and the color change is a side effect.

i hope so

probably.

Ive never heard of this and i really dont think its possible.

I have also read that treatment for melanin changes some eyes to brown. I suppose you could have blue eyes, but the melanin colors then brown. The colors come from the texture of the iris similar to albacore sea shells. The lines act as a diffraction grating so reflect different wavelenghts differently at different angles. There are contact lenses with colored Iris parts. Some yellow with cat pupils for Halloween.
