Have you reached the point of being unable to read clearly without putting reading materials in the distance? If so, you may consider a pair of prescription reading glasses. What kind of reading glasses to use may be your first concern. Reading glasses can be classified by glasses lenses, glasses frames.
Reading glasses lenses. In the category of glasses lenses, reading glasses are generally classified into single-vision reading glasses, bifocal reading glasses and progressive multi-focal reading glasses. Single vision reading glasses apply to seeing close up. If you have never worn any glasses before or you often spend a lot of time concentrating on material close-up, you can start out with a pair of single vision reading glasses. On the top half of bifocal reading glasses lenses, you can see in the distance; on the bottom half of lenses, you can look through the lenses for near work. However, this type of glasses lenses gives wearers kind of visual hopping. Progressive reading glasses are in common use. This type of reading glasses can meet visual needs from the distance of far, middle and near. Meanwhile, there is no visual hopping.
Reading glasses frames. Reading glasses come in two main styles, full frames in which the entire lens is made in the reading prescription and half-eyes that sit down lower on the nose. If you must spend most of your time concentrating on the near work, you can choose the first style, full frames. Remember to take off prescription reading glasses when unnecessary. It is not suitable for all the time. When wearing half-eyes, you can look down and through the lenses for the near work, and look up and over them to see in the distance.
Of course, more and more designer reading glasses appear in different styles, like tinted reading glasses, which can be used as a pair of prescription sunglasses that can resist UV rays for the protection of eyes. Meanwhile, the style of designer reading glasses becomes more and more closely with fashion, and then various fashion reading glasses come into being.
