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.
20/20 vision isn't perfect, it's just normal.. You can have better vision than 20/20. If you have 20/10 you see at 20 feet what most people see at 10. Some animals, like hawks, might have 20/2 vision! You can use our Snellen eye chart * to compare vision within your family or with your friends. (This will only give you an approximate idea of your vision. Your optometrist has much more precise tools to find out exactly how well you can see.) Each line of the chart is labeled on the left side. The second to last line is 20/20. Tape the eye chart to a wall, making sure it is in plenty of light.
