Why can you see your pulse in your vision?

Seeing your pulse in your vision, often referred to as "visual pulsation" or "pulsatile tinnitus," occurs when blood flow through the vessels near your eyes creates a rhythmic pressure that affects the retina. This phenomenon can be more noticeable in low-light conditions or during moments of heightened awareness. It's usually harmless and can be linked to factors like anxiety, fatigue, or changes in blood pressure. If it persists or is accompanied by other symptoms, consulting a healthcare professional is advisable.
