I used to do that before I had contacts. Now I just don’t care, just drop any old thing in my eye and I won’t flinch (this isn’t necessarily a GOOD thing!)
I don’t really do it that way because I’d flinch. I just like it because I can do it in front of a mirror without having to lean my head back and I can see what I’m doing and whether or not the drop made it in there. And it’s perfect for ointment. Just lay a bead down the inside of the lower lid.
