Why does my lacrimal caruncle hurt? today everytime i blink my eye it stings. is it because i recently got new glasses and the constant tear in my eye

Unlikely: Probably you need to see your optometrist. Glasses should not cause constant tearing unless it is in direct contact with the inside of the eye, which is unlikely. There might be something else going on, like allergy to something, foreign body or infection.

Benign inflammation.: This is a common area to have a mild inflammation of tissue. There are tiny glands that can get inflamed. It's not a sign of infection unless it starts getting large and pus starts draining. I would recommend warm compresses. If you develop eye redness or increasing pain and visual changes it would be good to have a more detailed exam done to rule out viral infection of the eye.

Well: Jerry glasses wouldn't cause this problem unless they're bumping against your eyelid. For specific diagnosis and advice recommend you see an optometrist ophthalmologist or primary care doctor it sounds like you may have an infection of the lachrymal duct or Island
