I have had a couple of episodes over the last couple of weeks where my vision has gone screwy for a few minutes making it hard to focus on anything. Once it starts to return I have a huge pain just above my right eye. There are no dark spots in my vision or even cloudy. It is more like not being able to focus. I wear glasses to read but have good distance vision except when the episodes happen. I have had my eye site recently checked in July and everything was ok. I am a male, 60 years old. 5'11" at 210 lbs. I had kidney surgery in June 26 and had a mass removed with good margins. The mass turned out to be cancer. But everything was removed.
