Since I wear glasses myself, I can of course really appreciate this pattern. It’s a very humorous couple. If you make a spec holder which looks similar to a person for whom the spec holder is intended for, it would be even more awesome.
You can download the free crochet pattern of the Spec Holder Grandpa and Grandma on the website of Zhaya Designs. You will have to scroll down a bit on that website to find the English download link.
