It's a Wonderful Cure for Bad Eyesight

Now that the Christmas season is upon us let me nitpick something that bugs me about the classic movie It's a Wonderful Life.   

When Jimmy Stewart is alive and him and Donna Reed are busy making kids - her eyesight is perfect. No eyeglasses for Donna Reed. But when Jimmy never existed - all of a sudden the librarian / spinster Reed needs eyeglasses. What happened? 

Now you can argue that she needs glasses because as a librarian she reads more books but I'm not buying that. I think Frank Capra was trying to send out a pro-sex message. Sex is so good it makes your eyesight better! Jimmy Stewart's cure for nearsightedness (that would be a good name for a band - well maybe not).
