I am 3.5 yrs past my concussion and light sensitivity and eye issues are my biggest remaining symptom. I still wear sunglasses anytime i am outside rain or shine, and I have double vision when I am tired, (letters have shadows above them.) Also I notice at night I have trouble reading any lighted signs, especially ones where the words are written in green lights. Red gas station numbers will be blurry but green ones are a giant blob. I have seen a neuroopthamologist a few times and he has never offered any solutions, just says to give it time. Maybe I should look for someone else.
