Cigarette smoking does not change eye color. The iris, color, blue or brown generally, is genetic.
Is this what you are referring to?
Customer: replied 6 years ago.

yes, can the nicotine stain it so it looks different. Or is there another reason that eye color would change. Another Dr. said it is possible for the nicotine to stain the iris of the eye.

I did smoke alot for a couple of days one cigarette after another as I was going thru a very stressful situation. Could that have done it and can it be reversed?


Expert:  Dr. Thomas, MD replied 6 years ago.
Iris color is an extremely complex phenomenon, but there is really only one pigment, melanin.
A yellow tinge can be seen in diseased eyes which is a wear and tear color from a substance called lipofuscin.
There are not studies that indicate smoking changes eye color. However, many believe that subtle changes in eye color happen due to many environmental influences. The whites of the eyes will often reflect disease states with the bloodshot appearance or with a yellowing.
Smoking has been reported to cause a slight yellowing of the sclera, the white of the eye, and this should reverse with smoking cessation.
Changes in the iris of the eyes [the colored part surrounding the pupil] are unlikely to be due to smoking.
