Since a little while after the dry eye started, Tristan has been squinting into the camera. I assume it's focusing/range-finding lasers that bother him a little more than he's used to.

I often deal with "don't want to look at camera" by asking dogs to look at me, instead. But Tristan is too much of a pro to look away. He knows what this is about, and he is GOING to do his job, thankyouverymuch. I am wondering if there's some way to relieve the lights in his eyes while still getting pictures in focus.
