Bemis. should have waddled over to the town drugstore and tried on all the glasses until he found one close enough.
If nothing else a globe with water in it would have allowed him to read up on how to customize a pair.
Yup, he was so smart reading all of those worthless entertaining books all of his life, but in reality he was stupid. One of my least favorite TZ episodes.
He should have found a small pointed object like a pencil tip or pen tip and used it to make a pair of temporary pinhole glasses using a book cover.
You can see clearly through a pinhole held near the eye...it acts as a lens does with a very small F value.
Once he had the rudimentary pair he would be able to fashion a better pair since he could then see clearly.
Works best in bright light.
This is why those old pinhole cameras worked so easily....
This effect is also why the very sensitive camera but with a tiny lens opening in a smartphone gives a pretty sharp image with no focusing.
The first eyeglasses were actually monocles made from a thin slice of wood cut from a small round branch. The wooden monocle would be smoothed down and then have a tiny hole gouged through the center. Once placed on the eye it would stay there and in good light the user could see very clearly.
If the light is very bright you can get so close to an object with the simple monocle that it becomes a low-power microscope.
I guess this is a bit of prepper knowledge from the distant past :-)
They don’t carry glasses with corrective lenses at the corner drugstore.
He’d have to fight the zombies on the way there.
That was going to be in the sequel but the series was cancelled.
