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.
What do the NUMBERS mean on binoculars and spotting scopes? This is the most common question about binoculars and it is a good one. You will see combinations of numbers like 7x35, 8x42, 10x50 or 7-15x35 and many more. The numbers to the left of the x always refer to how much magnification the binocular has. The number to the right of the x indicate how big the lens is at the bottom of the binocular (this is called the objective lens). So, 7x35 means this binocular magnifies objects so they appear 7 times closer.
