Study after study has shown that people fear vision loss more than they fear cancer, stroke, heart disease, and other serious health problems. But a new study shows that Americans are scared about an issue they know very little about. And what they don’t know is putting them at risk of vision loss, including blindness.

A survey[1] conducted by The Harris Poll shows that while 81% of adults say they are knowledgeable about eye/vision health, less than 1 in 5 (19%) were able to correctly identify the three main causes of blindness in the U.S., which are glaucoma, age-related macular degeneration (AMD) and diabetic eye disease.

Why does this matter? Because most people are also unaware of key facts that could protect them from vision loss, according to the survey. For example, only around one-third of adults (37%) know you do not always experience symptoms before you lose vision to eye diseases. And less than half (47%) are aware your brain can make it difficult to know if you are losing your vision by adapting to vision loss.
