<a href="https://www.healthmedsrx.com/product/bimatoprost/" rel="dofollow">bimatoprost</a>  controls ocular hypertension and glaucoma, although it does not treat either of these disorders. Even if you feel better, keep using the specified amount of bimatoprost eye drops. You should never stop using bimatoprost eye drops without first talking to your doctor. When using bimatoprost eye drops, the skin around your eyes may darken and turn brown. It may also cause your lashes to grow longer, darker, and thicker. These changes frequently occur gradually, but they may be permanent. If you use bimatoprost in just one eye, you should be aware that there may be changes between the two eyes after using it. Give your doctor a call if you notice these changes.
