To combine messages from George and ChasSmith:
George, it seems I do have glaucoma. So, I can no longer stare at a screen for eight hours a day. It was good to retire when I did. Baking doesn’t require looking at a screen, so it is resting my eyes.
The treatment is one eyedrop in each eye, every single night for the rest of my life. If I forget one night, I must take it in the morning.
