For the past couple days my eyes have been watering immediately after i get in the car and my eyes seem to finally "realize" that they are in natural light. It takes them almost 15 minutes to recover and go back to normal. It's not painful, it's just really uncomfortable. Although I have had a lack of sleep in the past few days, I do not feel like my eyes are try to shut because im tired, just because they are so sensitive to the natural light. I cannot remember this ever happening to me before to such a large degree. My eyes only water a little bit when I watch fourth of july fireworks. Thanks for you help!
