I have a rare eye condition related to caffeine. If i drink caffeine for a few days (any form - coffee/coke/,,) i get retinal stroke. basically some capillaries in the eye block and i develop blind spot. I see noisy spot for a few days in vision and the visual system adjusts in software and i no longer see the noisy spot. This stopped happening completely since I stopped all caffeine. Some years back I drank coffee for a few days and happened again. Since the topic is heart related I am wondering of there is a connection to blood vessels damage. Maybe caffeine acts as a mild stressor? mild stressors are known to trigger the protective systems and thats why we see the benefits with respect to heart?

It goes away in a few minutes, but it’s scary the first time. I believe it’s because caffeine has a vasoconstriction effect, it can reduce blood flow to the retina, the same happens on the brain (lots of small capillaries), that’s why people get headaches on coffee addiction too.
