CLEAN SPECTACLES
You wipe the spectacles with the white cloth and before long they are much cleaner and obviously due to some magic, the crack in the lens has gone.

GIVE SPECTACLES CRONE
You hand the spectacles to the old woman, who mounts them carefully on her wrinkled nose.
"I can see!" she warbles, her cracked voice raised in an ecstatic cry.
"I must reward you, my friend. Come with me to my bedroom and I will spin you some clothes for you to wear!".
The old woman hobbles out, motioning towards the upstairs.
An old woman hobbles in and takes her seat by the spinning wheel.
The old woman begins to spin, the thread whizzing along the spinning wheel, her dextrous movements amazing you. You stand aghast as the old woman weaves a beautiful piece of clothing.
The woman looks about her, and mentions something about supplying the weaver with another shirt.
