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.
The first number(s), in this case 3.5-10 or 4, is the power. Power expresses the magnification as a factor compared to the naked eye. So in a fixed power scope, such as the 4x32, the object in view is magnified 4 times. An object would appear to be 4 times closer than it would with the naked eye.
