Is there any natural way to change my eye color? I have dark brown eyes and I want blue.

There are no ways to change your eye color other than wearing color contacts.  You would need to get a prescription from an eye care professional for these. 

Thank you for your question. Latisse will only change small spots of the iris in green eyes to a brown color as a side effect. Latisse is not to be used to change eye color. Best, 

Other than colored contacts, there is no other way to change eye color than I am aware of.  Dark brown eyes are as beautiful as blue eyes!

Absolutely do not use Latisse to try to change your eye color. This is not what it is intended for and it will not be a good idea. "This answer has been solicited without seeing this patient and
