Bye Bye Blue Eyes
People with light eyes usually have a low amount of melanin in their irises. Melanin is the pigment that gives skin, hair, and eyes their colour. So when glaucoma patients with light eyes take the prescription Xalatan it may change their baby blues into brown. Xalatan can cause the eyes to produce more melanin, which causes them to have more pigment in their irises, therefore changing them to brown. What is worse is that the discoloration can be irreversible.
