Besides  nearsightedness and farsightedness, eyes can be subject to various problems such as floaters, astigmatisms, double vision, conjunctivitis, and even parasitic infection. As we age, macular degeneration, glaucoma, cataracts , retinal detachment . . .  and even blindness affect some people. The eyes depend on high quality antioxidants, especially as found in berries and some fruits and vegetables. They need good circulation, protection from certain spectrums of light and radiation, and healthy living habits. Paying attention to blood pressure is one matter, but periodic detoxification of the liver also has amazing benefits.
