Hello and thanks for your question. Yes, your eyes can be red from staying awake all night. However, in my experience, it usually takes something more than that to make them significantly red, such as allergies, or possibly an on-coming viral conjunctivitis. If your eyes are significantly itchy, then I would recommend and OTC allergy drop.
Does that make sense?
My eyes don't itch.
Then, I think you are okay to just keep an eye on this (no pun intended) and use artificial tears 3-4x/day if you wish to help with any irritation. But otherwise I wouldn't worry about it unless you started to develop other symptoms such as pain, light-sensitivity, or discharge.
Not right now, but earlier today, my eyes were sensitive to the fan blowing full blast in front of me. Should I be alarmed about that?
No,. not really. That's just a sign that there has been some minor irritation, probably from the lack of sleep, and something that I think the artificial tears would do well to help. Very common and nothing to worry about.
I am also trying to combat Afrin addiction right now. That's one of the main reason for my allergies, I think.
Ah, I got ya. That's difficult. Do you have any other concerns or questions about this topic?
I am trying to take Omnaris instead of Afrin to see if that will take it away. Are red eyes a possible side effect for Omnaris?
No, this is not a normal side effect of Omnaris.
The Omnaris seems to help a little bit. Thank you.
