A member asked:

I can see my peripheral vision pulsate with my heartbeat when im in brightly lit rooms. what is this?

A doctor has provided 1 answer

Lid effect: You are seeing the effect of narrowed lid opening off to the side responding to each arterial pulse. This is not an effect inside the eye./ This is a function of the excellent degree of your perceptions and not due to anything that is abnormal or pathologic.
