Sunday Sept. 24 Challenge. "Transition".

"Transition"

One of my granddaughters.

I found this about "transition lenses":

With transition lenses (also known as photochromic lenses, their technical identity), your glasses automatically darken in response to the amount of UV light that’s present, and clear again when that source of UV light is gone. In other words, they’re the ideal combination of prescription glasses and sunglasses – clear at night or when it’s cloudy or shady, dark when outdoors in the sun. With transition lenses, one pair is all it takes to cover all light conditions.
