There's no such thing as a strange question. If you're concerned with anything about vaping this is probably the best place to go for decent anecdotal advice but if you're in doubt I'd see a doctor to be sure if it worsens.
Don't read too much into this as everyone is different, but when my eyes feel tingly/tight is my sign to stop vaping. I had to stop using pg entirely as I'd get that tight eye feeling pretty quickly then break out in a bad rash if I used it for a few hours.
Even with vg, if I have too much I feel it in my eyes first. I put it to nicotine more than anything as I can vape much more low nic before my eyes go and I can vape no nicotine all day and not feel it once. To me, it's a too much nic too fast warning sign that kicks in before the heart palpitations, and if I keep going the nic headache and throbbing temples.
It may not be the case for you but it could just as well be. Order in some vg or at the least lower nic and try it out. If I vape even 6mg I can get that feeling. I think because my metabolism rate is through the roof it gets into my system so quickly it doesn't matter if it's low or not.
Everyone's different. I read some guys using 32mg+ liquids and I can not go any higher than 18. I'm comfy at 6mg or lower and wonder how anyone can even inhale 32mg.
If it's not because of nic, you could put a little vaseline under your eyes to stop the skin from getting irritated as well. My partner does it for pet allergies to sooth and protect the area.
You'll be glad you asked if that's what it is. Hope you find a solution and shoot us a question any time. Someone will help you out
