Perception that lights are dimming

Over the past month or maybe longer, I have thought our home lights are flickering -- dimming for about a second and then returning to normal. I believed this to be a house electrical problem, but my husband consistently denied seeing the lights dim and he never reacted at the times when I saw the lights flicker. Still, I thought he just did not want to pay an electrician.  But today in the supermarket I experienced the lights dimming, and nobody around me reacted. So I am now concerned that I have a medical problem. This happens once or twice a day, almost every day. I have no pain when this happens and I do not notice any other problem except the dimming of light. It is the same perception as when a cloud briefly covers the sun.

History: Female age 62. Anterior uveitis in both eyes starting 2008, but no flares within the last year. Cataract surgery one eye, 2 years ago. Vitrous detachment, hemorrhage, retinal tears and laser repair (cataract eye) one year ago. Suspicion of auto-immune problem starting 2008 (because of sudden uveitis, pleuresy, joint problems), but tests inconclusive at first and then all negative when tested again, and symptoms alleviated. New eye glasses. Eye exam within past 3 months with no problems noticed.

Update: The first test I underwent was last week, a CT scan with contrast.  Brain aneurism!  Underwent cerebral angiogram and was advised to undergo treatment. Waiting for soonest date on coil procedure. Thank you for taking my question seriously. I love my ophtho, too.

Thank you, Dr. O. I was able to see my ophthamologist today. My eyes checked out fine but she had the same other concerns you listed and scheduled me for a visual field test and sent other testing recommendations to my GP.

You should see an ophthalmologist.  This could be due to carotid artery or cardiac disease or an ocular problem related to your other eye problems. It could also be due to posterior circulation problems (not likely since you do not have any other symptoms.
