Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

Amy Joyce:

FYI Ruby's glasses were bifocals. 

"one pair black horn-rimmed bi-focals"   WC exhibit 1322

Maybe this will help your argument in forum?  Maybe they didn't make tinted bifocals back then.  

Ralph Cinque:

Thank you, Amy, and here is the link if people want to see the document themselves:

They certainly were not sunglasses, and there is no reason to think that horn-rimmed bi-focals would be tinted. Besides, as detailed as they made the description, surely they would have said so if they were tinted. 

Here is an image of Ruby wearing glasses at his trial.
