A member asked:

How do the numbing drops during an eye exam work?

A doctor has provided 1 answer

Anesthetic: the drops that are used are usually proparacaine, which is a topical anesthetic. It's just like the stuff the dentist gives you. In the old days, the drops that were used were cocaine-- which is a topical anesthetic as well-- but that's not done very often anymore for obvious reasons.

What's in numbing drops that optometrists use that makes your eye numb? Is it similar to lidocaine that dentists use in your mouth? I'm just curious.
