Have you ever had an eye exam? You probably remember the doctor putting some drops in your eyes. After a while, your eyes feel a little blurry, and when you go outside, your eyes feel like they're turning blue. Many people are a little scared about this. Why do they actually put this kind of medicine in your eyes? What happens with this? Let's talk about this today.
What really happens with this medicine?
Simply put, it's a combination of two medications: Hydroxyamphetamine and Tropicamide . These come in the form of eye drops. Their main function is to dilate the pupil, the black part of your eye.
Imagine that a doctor wants to examine the inside of your eye. For example, they want to get a good look at the retina or optic nerve at the back of the eye. Normally, the pupil is small, so looking inside the eye is like looking into a room through a small keyhole. So by using this medicine to enlarge the pupil, the doctor can see the inside of the eye clearly and completely. This is something that is usually done during an eye exam. This medicine is also known by the brand name ``(Paremyd)``.
