Yes. I have it, my son had it, and my grandson had it. I wear sunglasses and didn't go out in the sun a lot. I was told to have my five year old son wear glasses and I bought him a pair, he went to the park and came back without them. My grandson got laser surgery for near sighedness and it was very expensive due to large pupils. We have blue eyes and I have almost perfect vision still, I just wore sunglasses and stayed out of the sun mostly which is like many conditions, manage them and you will be okay. Large pupils is a sign of sexual arousal, and I worked in a hospital so I got a lot of attention from male doctors who may not have known about photophobia. My son asked what photophobia was and was told it meant he was afraid of light, he said No, I am usually afraid of the dark.It isn't a big deal.
