The macula is the tissue inside the eye responsible for central vision. If that area breaks down and becomes wrinkled, it is called macular degeneration. Smoking is the biggest risk factor, and family history plays a role as well. Green leafy vegetables help keep the macula healthy. For those with risk factors that don't eat their veggies, adding a vitamin can be helpful. This new one from Centrum contains the recommended amounts of lutein (10 mg) and zeaxanthin (2 mg). We have samples at the office if you are interested.
