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.
Everyone's eyes are different and so are the types of vision that we have. Understanding how some of us see differently and how the eyes change over time, will help protect your vision. Normal vision, often called 20/20 vision, means that you can see clearly objects that are 20 feet away. However, 20/20 does not necessarily mean perfect vision.
