I have been suffering from vision problems for quite a few years. Usual eye exams shows everything is normal. Some of the symptoms are: hyper sensitivity to sunlight, seeing white walls as slightly yellowish or brownish, suffering while using computer LCD or LED monitors, requiring stronger (brighter) lights at night, sometimes vision is blurred or a white area in the vision center appears for a short while (this is rare). I am over 50 years old, with high blood pressure and I wear prescription glasses.
