I don't think so not for the price we had our first building burn down I ran into a burning building trying hard to save me friend if I had this mask he would be alive smoke kills most people if you don't live on first floor you should have this mask next to a flashlight it fits great I only wish I had it Nov 6th I hope this helped I also bought fire proof gloves

Q: Will I be able to wear this mask over my eyeglasses?

No it won't. If you have glasses like me full face mask won't work because it'll compromise the seal. In some sense you can but it will leave an opening where you'll end up breathing in the dust or vapor where your glasses are.
