I have been using my left eye, closing my right one, when looking through a viewfinder. Am I the only one? I have seen most photographers use their right eye and close the left eye. It is kind of hard for me to change now. The reason I post the topic is because lately, after shooting about 30 minutes with my left eye while closing my right, my right eye get blurry and it takes about 15 minutes to get back the normal vision. This is after clearing my glasses. Does this happen to anybody?
