                        Hello Eileen:    I have the condition known as achromatopsia, which I have known for years.  However, the actual diagnosis was made just recently when I went to visit a new eye specialist.    Although I completed school many years ago, I work very closely with various departments of educations, and have slightly over 50 years experience living with the eye condition.    I am extremely sensitive to bright light, which is expected with the condition.  Over the years, I have had th eoppportunity of meeting and comparing notes with a few other achomats,   and it seems that I am more sensitive than others.  Even with the most ideal sun glasses, I am still very uncomfortable outdoors on a bright day.      If you wish to correspond about this subject and your daughter, I would welcome you doing so.  I find it always helps to talk these things out.  I could write much more now, but I am not even   sure if you will get this message or not.  Please write me at  anytime, and I will definatly respond.    Yours Truly,    Gary
