As per the American Optometric Associations’ (AOA) Eye-Q® Survey 2020, about all Americans take their eye health seriously and give it as much importance as they give to their heart health. But on the contrary, nearly 50% of them, aged between 25 to 35, don’t give importance to comprehensive eye exam if their vision is clear. An eye exam is a comprehensive diagnosis process that is more than merely a vision test. In fact, it helps an optometrist to detect some early symptoms and indications of more than 250 general and chronic health problems including diabetes, high blood pressure, and others. Instead of x-ray and CT scan, many doctors ask for an eye exam to examine the blood vessels behind the eye.
