Next time, while at the pharmacy, pick up an eye patch. Proclaim that it must be worn for 7 days. If you take it off a moment too soon, you will need to wear a patch on both eyes.
The good lady is likely too smart for that. She’ll remind you that there’s no steemit when there are two patches.
She would probably ban me from steemit if I even wore one, although the temptation is strong to try it!! ;0)
