Can special eye drops change your eye colour? If yes, are they safe?

Yes, there are eye drops that can change your eye colour, but they are not safe. The active ingredient in most of these products is hydroquinone, which is a skin lightener. It works by inhibiting the production of melanin, the pigment that gives skin and hair its colour.

While hydroquinone is effective at lightening skin, it can also cause serious side effects, including yellowing of the eyes and skin, darkening of the skin around the eyes, and irreversible thinning and weakening of the eye's retina. That's why it's important to only use products that contain hydroquinone if your doctor has prescribed them for you.
