lost shades

If an image appears on sunglasses and no-one's wearing them to see, does it exist?

Walking home from my son's prize-giving this afternoon and came across these dropped (or discarded) shades. Someone had kindly picked them up and hung them on a fence just at the location where the lawn bowls will be for the Commonwealth Games.

So the image on the lenses is an impossible one. A wearer could never contort their head to see such a thing. What is interesting to me is the idea that different points of view are always around us. From any fixed vantage point we have a habitual view, but there are also these other visions if we have the equipment to try and break down the everyday view and explore and see others.
Our worldview is also a bit like this. We are such creatures of habit that we pass up microcosmoses of possibility that are there in our every step. Obviously it would be crazy, mind-boggling and dizziness inducing to constantly test and try to get novel views on well kent things. It is simply a reminder, to me at least, to keep the antennae alive and attuned for other possibilities in the day. Too easily we pass the day by in a dwam.

Onwards.
