Anti-Slip Glasses Ear Grip - 3 Pack - Stretch Fit for Sunglasses and Glasses Retainer Glasses Chain

Q: Will these keep glasses on while on a roller coaster?

This product is for preventing your glasses from sliding down your nose. I would not recommend using this product while riding a roller coaster, it will fly off your face (I'm talking about your glasses). Hope this helps.

Q: Will these grips raise my glasses to prevent nose dents?

I bought these anti-slip ear hook grips for my eyeglasses to “not” fall off my face and they work. The answer to your question, I don’t know if they will raise your glasses to prevent nose dents…Buy pair of the anti-slip to see if they work.
