The word Chamomile comes from the Greek meaning ground apple, probably because of its apple-like fragrance. The Romans used Chamomile for incense. Roman Chamomile gained its name, not from ancient Rome, but because a 19th century plant collector found some growing on the ruins of the coliseum in Rome.
What Is Perfect Vision? In cases of normal vision, also called perfect vision or 20/20 vision, the eye is able to focus light from objects precisely on the retina at the back of the eye. Refractive errors occur when the eye is unable to properly focus light on the retina.
Best corrected vision has to be 20/200 or worse in both eyes. Peripheral vision or visual field reduction also can qualify you. If your glasses and/or contact lenses improve your vision better than 20/200 in either eye then you are not legally blind. You can have a massive prescription yet be 20/20 with correction.
