Gill....I've reviewd your question, and it does not sound like your eye problem is related to the non-smoking issue. The shimmering symptom sounds migraine related, but the prolonged sensitivity to light worries me. Do you have an ophthalmologist?
Sorry....the system locked up....No I don't think that from your symptoms, that like your mother , that this is a sign of " going blind"....but it worries me that there is the light sensitivity...and that is why I would want you to come in to let me check if you were my patient.
Is there anything else that I can answer for you?
