The world is flat

It's true, it's official! The world is flat. At least it is in my eyes!
Stereo vision lets us see the world in three glorious dimensions but to get it needs two eyes and right now I can't muster much more than one. Monovision. Depth disappears and the world is flat.
It's an unexpected handicap. My spatial judgement is up the creek. I go to close a cupboard and miss the handle, misjudge the depth of a step.. and stand like drunk at the door, the key circling in on the keyhole. Pouring from the kettle? Cutting veg. Just shaking hands. New challenges.
I'm taking drops that dilate the pupil and relax the eye.. which means no focus regardless of what my eye might otherwise manage. Looks like I am going to have to get used to it - this flat earth.
Excuse me while I - carefully - pour a beer...
