The above is a typical case from our customers. According to his description, his reading is +2.25 and driving glasses is +1.50 OU that means his ADD should be +0.75. Currently, some websites could only provide bifocal lenses with +1.00 bottom power (ADD). When he uses it for reading, please move the objects a bit further. (+0.25 will not affect any discomfort for reading use). Normally, bifocal lenses can be divided into two general categories: regular bifocal and progressive. Regular Bifocal lenses were created to rectify the multiple vision problems, affixing a smaller lens of a different prescription to the bottom part of a larger lens in a pair of glasses. They have also been in existence for a long time, and come in several shapes: half cut, round, rectangular, and half-moon or “D-shaped” (the latter being the most popular). While these types of lenses allow the wearer to use the upper, less convex part of the lens for long-distance viewing and the lower, more convex part for close-up tasks such as reading, they involve a problematic “jump” from one focus to another. In addition, there is a “no-line bifocal” lens, which is called as progressive. Some people feel faint when reading even if it last only several minutes with the distance eyeglasses, and his eyes got blurred, which bring them too much trouble. At this case, some of them will pick up a magnifying glass, but the result is not that satisfying. If ordering a pair of progressive glasses, and then the feeling of faint will release a lot. In addition, there is a new optical product, which is Free Form Progressive lens. Due to choosing different kinds of progressive lenses will help to satisfy for different group’s wearer with specific needs.
