Like you, I started experiencing unexplained sensitivity to certain lights, especially white headlights at night, Christmas lights in bars, and a few more instances of transient floaters, light themes on the computer seem to ever so slightly blur my vision which was not a problem before - but not to the point of things being unreadable. I also felt that airflow to the face on the motorbike is more irritating on the eyes than I've ever noticed.
I went to Rutin as recommended by many, and a number of hours later was found to have dry eyes, prescribed eye drops and lotion, and sent on-wards to the cashier. Today, I'm still trying to get to the bottom of this though, particularly the suddenness of the symptoms and the reasons behind the onset of dry eyes, whilst it was a relief that nothing serious was uncovered I want to focus on regaining optimal eye health or stabilizing any deterioration, thus looking for a clinic where I can discuss things first with a doctor at length before going on the test circuit, a clinic for the minor issues if you will, open to suggestions?
To the OP, how are you sure your tear ducts are functioning correctly? The dry eyes diagnostic was a little bit of a surprise for me, but I kind of notice it now its been highlighted... even though there are times when I do feel my eyes are watery for example after exercising to a sweat for 20minutes.
