Learn about your risk for vision loss and how to reduce it with these effective health tips!
Your eyes are one of the main tools that you use to experience the world, but they represent a real paradox to the body. Eyes need to let light in so you can see the world, but that same light can cause damage.
Almost 3 million Americans are affected by macular degeneration, a disease caused by hereditary and environmental factors that creates vision loss. Discover more about macular degeneration, if you are at risk, and what you can do to help combat its effects.

How Does Vision Work?
When you look at an image, light enters the eye through the pupil and strikes the lens. The lens bends the light, focusing it on the back of the eye - the retina. The light is converted into neural signals passed along the optic nerve to your brain which tells you what you are looking at.
The oval shaped area in your eye that captures the details of the image is called the macula. When the macula is damaged, as with macular degeneration, the image your eye captures will lose its definition and appear blurred.
