Can High Cholesterol Affect Your Eyesight?
Many people think of high cholesterol as a heart issue, but its effects can extend beyond the cardiovascular system—even reaching the delicate blood vessels in your eyes. While high cholesterol itself doesn’t directly cause vision loss, it plays a significant role in damaging small blood vessels over time, particularly in the retina, the light-sensitive layer at the back of the eye.
One serious condition linked to elevated cholesterol is retinal vein occlusion (RVO). When cholesterol and other fats build up in the bloodstream, they can contribute to narrowing and blockage of the tiny veins that supply blood to the retina. If one of these veins becomes obstructed, it’s called a retinal vein occlusion. This condition often strikes suddenly and typically affects one eye.
Symptoms include sudden blurring or loss of vision, floaters, or dark spots drifting across your field of view. These aren’t always painful, which can make them easy to dismiss—but they’re a red flag. Early diagnosis is crucial to prevent permanent damage.People with high cholesterol, especially when combined with high blood pressure or diabetes, are at greater risk. The good news? Managing cholesterol through diet, exercise, and medication when needed can go a long way in protecting not just your heart, but your eyesight too.
Regular eye exams are more than just a check for glasses—they’re a window into your overall health. If your vision changes suddenly, don’t wait. See an eye specialist promptly. Catching issues like retinal vein occlusion early can make a lasting difference.
