My grandmother uses glaucoma eye drops, and her lashes are indeed long, thick and healthy. However, I'd personally be extremely cautious about using a drug meant for a condition I didn't have. Jan Marini's original product, Age Intervention Eyelash, was pulled from the market last year. It had the potential to cause loss of vision among other side effects. It contained bimatoprost, the drug mentioned in your quote below. Here are some links that might be of interest on this topic:

Bottom line: do your homework. Read up on possible side effects and be willing to accept them if they happen. I don't always believe in health over beauty , but when it comes to my eyes and my eyesight, I don't mess around.
