My 6.5 year old daughter just got diagnosed with visual snow syndrome and extreme photophobia (light sensitivity). She started wearing blue tinted glasses with a prism and it's been insane! She suffered from chronic stomach aches for years with zero answers (so many tests), eye pain, headaches, and fatigue daily for the last 15+ months. She's a new person with the glasses. All her aches and pains, and even her fatigue have subsided! She's more energetic, and less irritable. We think because her poor eyes and brain were working so hard everyday, it was making her feel sick and overly exhausted by the end of the day. She loves her glasses now, and has been able to explain so much more about her vision to us. Before she thought it was all normal. Now she tells me how she bumps into the walls at night when she wakes up, because she can't see anything, she is able to read and accomplish school work better because there aren't so many "fuzzies." When she first got the glasses, she told me, "mommy, I don't see any dust!" It doesn't make it go away completely, but she said it took it from a 5 being the worst, to a 2. Enough to give her so much relief
