Looks like he actually tried it:

  But some ideas cannot be crushed by bankruptcy and the dream of providing lenses to all of America’s hens was carried on by the son of one of Vision Control Inc.’s founders, a young Mr. Randall Wise. Wise, a Harvard Business school graduate and former nautical shipping consultant, used the millions he made from selling his software company to establish Animalens, Inc.

 Instead of pecking at each other (success!), the hens were now pecking at the air, rubbing their eyes repeatedly on their wings, and suffering from corneal ulcers and ruptured eyes.
