Winter light is not the same as summer sunlight. You’d think after practicing walking — seeing, perceiving with both eyes and feet together, learning where I am in space — during strong and long summer sunlight hours, I’d have no trouble in the winter. Nope.
It isn’t just the snow.
The sunlight is sharp, throwing long rays through polarized sunglasses. Bare trees cast patterns of shadow and blazing light in a repeating rhythm as you walk. No matter the hour, the low sun sends photons into your eyes instead of down to the top of your head. And white, gleaming snow reflects it back up.
My brain remembers how my scarred eye used to shut and, in its diabolical plan to return my vision to what it was used to, tries to convince my eye it still doesn’t like the light. I have to fight to perceive that its light tolerance has improved, except when looking extremely sideways to the left. Even when back indoors, my brain is like, hey, it didn’t like the light so let’s shut it against inside light too! Grrr. It doesn’t help my good eye is sensitive to the light as well. (Yes, before my brain injury and eye surgery, I’d walk familiar routes with eyes shut on bright winter days.)
My CNIB guy suggested I get the sunglasses with the top and side panels. That way sun rays can’t sneak around the frame edges. Old people glasses, I think. But then he’s way younger than me and his pair not only has the panels but also sit over his glasses. Then I noticed the baby boomer generation growing older means seeing others my age wearing them too and looking not old, looking chic. But where do you get them?
