Well, I could add, me too, but that would be oversimplifying.
In August of 2010, I figured out I was somewhere "on the spectrum", after fifty one years of not understanding what was "wrong with" me.
In early October of 2010, an eye doctor finally figured out exactly what I was born with all those years ago - ocular albinism. Which means my eyes are naturally light sensitive. That wasn't a surprise to me - as a kid, I got in trouble with eye doctors all the time for flinching away from the lights. And I once got in trouble in high school for swearing at a kid who popped a camera's flash in my face, and they wouldn't accept I found it as painful as a physical attack. But, in another way, it was a surprise: my light sensitivity bothered me so much less than certain other sensory issues that it had become somewhat lost and buried among all the others. Which meant - since I had a diagnosed, physical reason for something that didn't even stand out, I figured that certainly proved my sensory issues must be more than "my imagination". I still figure that.
But now, I read this thread, and figure maybe I am sensitive to light from two angles...
And, yeah, long before 2010, I had trouble because when I came out of a building into the sunlight, it would take a minute or two before I could really get my eyes to open. It's pretty freaky trying to walk when your eyes are clamped shut... although, whenever I could, I'd stop short, of course. In the snow, when the sun came out, that was a real ordeal.
Edited to add: The diagnosis of ocular albinism was not based on my light sensitivity: he actually took a photo of my inner eye. That was an ordeal - I had the "shadow" of that flash imprinted on my eye for an hour or two. I essentially don't have normal retinas - all my vision is reliant on what in most of you would be your peripheral vision. Even among the nearsighted, I am weird.
