Hey, I never said long-term use wouldn't cause negative effects. Let's be real clear about that. What I said was that an ophthalmic solution that causes vaso-constriction in capillaries wasn't likely to cause vascular collapse. If you want to take issue with what I said, you need to make sure you're reading me clearly.

I don't advocate long-term use of vaso-constricting eyedrops, nor, I expect, do any eye doctors. My doctor recommends Opcon-A for occasional use during allergy season for me.
birdgirl73 Reviewed by birdgirl73 on . Eyedrop...Any long-term problems with daily use I use Clear Eyes almost exclusively. And multiple time per day;) Does anyone know if this could be risky. I mean, are there any negative long-term effects by using eye-drops? When I was young...a friend of mine's dad had used too much nasal medicine and it fucked him up real good. I would hate to be blind in 20 years or something! Anything would be helpful....thank you and take care. Rating: 5
