how to reverse pupil dilation?

Answer 1

There are eye drops that constrict the pupil.

Bright light will cause a normal pupil to constrict.

It sort of depends on what caused the pupil dilatation in the first place.

If you have had dilating eye drops from the eye doctor so they can see the back of your eye, the easiest thing is just to wait it out. It should reverse itself over a few hours. (There is one type of dilating drop that lasts a couple of days but your doctor should not have been a doofus and used that OR they should have explained why they want to dilate your pupil for a couple of days).

I would. I never had a dilated eye exam until my twenties and was wearing the wrong prescription, probably since elementary school. Pupil dilation does have a number of purposes. It allows your doctor to examine the back of your eye and make sure the structures are healthy (ie your optic nerve and retina). It also temporarily paralyzes the muscles that constrict your pupil and allows your doctor to objectively measure your need for glasses (or contacts) with a retinascope. Based on the way the light bounces off the back of your eye, your doctor can determine what prescription will focus rays of light on your retina (the back of your eye that turns light into electrical signals that are sent to the brain) to allow you to best see clearly. When your pupil constricts (b/c of the light being shined in your eyes), the measure for glasses is less accurate b/c you're changing the shape of the lens inside your eye. Your doctor should follow up with a subjective exam (the part where they ask you which is better, one or two) Different doctors use different dilating drops. Most adults are given the shorter acting drops. They may dilate your pupils for 4-6 hours, longer if you have light blue eyes. If you don't bring your own sunglasses, many clinics have temporary sunglasses, as your eyes may be light sensitive. Some clinics also have "reversing" drops to reverse the effects of the dilating drops. I would guess most insurances cover dilating drops, as it is a routine thing to have at an eye appointment, but you might want to specifically ask your insurance company. Like I said, I would do it. I wish I had it earlier. My prescription was off for years (b/c I had unknowingly been changing the shape of the lens inside my eye when reading the eye chart). I had a lot of headaches, etc. You should also get your contact lenses checked, especially if you're a new contact lens wearer. Sometimes they don't sit on the front of your eye as they're supposed to. Whoever prescribed your contacts should be able to check. I have astigmatism as well and don't see as well in soft contacts as I do in glasses b/c the lenses moved around and didn't "settle" with the weighted part of the contacts where it's supposed to be every time I blinked. Good luck to you!
