Hi Dr. Khu,
The wavy lines can last up to a minute or longer. They are random throughout the day. The wavy lines always have the gold glitter with them. When I move my eyes the lines and glitter have been staying on the periphery of my eye.
The "C" intermittent flashes has just been within the last week.
The only left eye issues I had prior to 2 weeks ago was pain of the left eyebrow- headache.
