I asked one of my high school patients what percentage of students text. He answered, "100%." when I started practicing almost 30 years ago the pc was coming on the scene. I saw changes of vision in my patients who were staring at screens at work all day. That hasn't changed much. When you text, the phone is a lot closer. It will be interesting to see if this added amount of close-up viewing will affect one's distant vision.

I had a patient whom I hadn't seen for over 10 years. Upon his eye examination, he commented to me that because we observed possible changes in the retina due to hypertension, I had referred him to his primary care physician. Indeed there was hypertension. His physician also ordered for him at that time a psa and subsequently found out the patient had prostate cancer. His doctor stated that if he would have gone six months longer, he may not have survived.
