There are more than 3 million new cases per year of people being impacted by farsightedness, also known as hyperopia or hypermetropia. This disorder directly impacts the refraction of light reaching the eye. The net result is that close objects cannot be seen clearly. As illustrated in the image below, the refraction, or bending of light, as it passes through the eye's cornea and lens, causes the light to focus onto a virtual point behind the retina resulting in blurred vision. What causes this disorder, and how is it diagnosed and treated? This article will try to address these critical questions regarding farsightedness.
