My eyes are super sensitive to light. When I close them I get a tunnell effect of intermittant dark and bright circular waves that seem to go in a direction away from me (or if you can imagine the reverse of the ripple effect that happens when a stone is dropped into a pond of water). This lasts for a few minutes until my eyes are rested but will start straight away again if I open and close my eyes. It happens in all types of light: Sunlight , florescent and normal bulb light but to a lesser degree with sunligght being the strongest. Can Anyone explain to me what is going on , I just moved to a really sunny part of the world that loves florescent light from a relativley overcast country.
