You've described the two things that has been happening with me. Glad to know I'm not going crazy. I'm aware of the first being possible migraines. I too have had high blood pressure only after mitral valve replacement in 2005. Since then I've had these problems. The second symptom really worries me because I drive and my vision is distorted for a few seconds when it happens. I will make an appointment with an opthamologist and come back and repost the findings.
Dear alanevil,
The first paragraph sounds like you may be having a migraine. Migraines can induce visual symptoms which may be followed by headaches. With regards to the migraines and eye musculature imbalance, I would recommend that you see an eyeMD to determine the diagnosis and treatment. I would recommend that you control your blood pressure and if needed, wear reading glasses to reduce the strain.

First problem is likely a classic migraine with visual aura. I am not sure about the second problem an suspect there may be no relationship with the first. Occasionally more serious problems can mimic a migraine so I think it is very important to see an ophthalmologist for a complete workup and perhaps see a neurologist as well.
