Bimatoprost belongs to a class of medications known as Prostaglandin Analogs.

It is an  effective active ingredient used in many eye-care products to treat Glaucoma and promote eyelash growth.

But can Bimatoprost cause eye color changes? Is it a myth or reality?

Although Bimatoprost is generally safe to use when used appropriately, it can lead to some side effects that may vary among individuals.

Hence, this article will explore the effects of Bimatoprost on eye color and ways to prevent side effects. 

Can Bimatorpost cause eye color changes

Yes, there is a chance that Bimatoprost can alter the color of your eyes

However, this side effect of Bimatoprost is extremely uncommon. Only a few people who take Bimatoprost have reported experiencing it.

The US Food and Drug Association (FDA) authorized Bimatoprost ophthalmic solution 0.03% in 2001 as an eye drop for treating Open-Angle Glaucoma and Intraocular Hypertension.

But unusual eyelash growth is a side effect of Bimatoprost

However, this effect can be beneficial for people with Hypotrichosis.

Hence, the FDA in 2008 authorized Bimatoprost ophthalmic solution 0.03% as an eyelash solution to treat Hypotrichosis of eyelashes.

Hypotrichosis of eyelashes is a condition characterized by an inadequate amount of eyelashes.

Some people using Bimatoprost for growing eyelashes may experience changes in the color of their eyes.

But the exact mechanism by which Bimatoprost changes your eye color is still not fully understood.

It is believed that Bimatoprost can stimulate the melanin pigment that gives eyes their color.

This can result in the gradual darkening of the iris over time, changing the color of the eyes to brown, especially in those with lighter-colored eyes (blue or green).

However, not everyone who takes Bimatoprost will see changes in their eye color.

These changes are often more obvious in those who use the medicine frequently for a long time in one eye only. 

This side effect of Bimatoprost can be permanent in  1-2% of Glaucoma patients who use the medication on the surface of their eyes.
