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.
Your vision is 20/200 or worse in your best eye, even with corrective lenses or surgery. According to the federal statute that defines legal blindness, a person also merits the designation if he or she suffers from severe tunnel vision, with a visual field that measures at most 20 degrees in diameter.
