I am 59 years old and was diagnosed with myoclonic seizures in 2006. I have a definite problem with sunlight which I have never thought to mention to my neurologist.
If I look up at a very tall tree or up at the sun, I had better be holding onto to something. I definitely get dizzy and feel disoriented for a minute or so.
I do not have a problem with driving in the sunshine. I always have a good pair of sunglasses and put the visor down if it is real sunny. My eyes have always been light sensitive. What about your daughter's?
My eyes are so light sensitive, I usually wear sunglassess to drive on a cloudy day.
Take care!
Carla
