Many people do not have the idea about progressive eyeglasses. Why we need progressive eyeglasses? Who needs progressive eyeglasses? Without enough experience about progressive eyeglasses, you may feel wonder what exactly are progressive lenses. However for people who are over 40 may have such problems that they could not see the near materials clearly. When they read printing materials, they need to put them in an arm’s distance to watch them clearly. That is called presbyopia. With the age growing old, almost everyone has such vision problem. Presbyopic people will feel troublesome to switch two pairs of eyeglasses when you change your vision distance from the near to the distant. Two pairs of prescription eyeglasses will cause inconvenience. Thanks to the development of our technology, today’s presbyopic patients are lucky enough to have progressive eyeglasses.
Progressive glasses are one of the three categories of multifocal glasses. The other two categories are bifocals and trifocals. Bifocal eyeglasses mean the lenses have two different powers in a single lens, while trifocal eyeglasses have three powers in a lens. However, progressive lenses provide a more natural correction of presbyopia than bifocal or trifocal prescription eyeglasses. Instead of providing just two or three lens powers like bifocals or trifocals, progressive lenses are true “multifocal” lenses that provide a seamless progression of many lens powers for all viewing distances. As a result, sometimes progressive lenses are also called “no-line bifocals”. With progressive lenses, you can look up to see clearly across the room and in the distance. You can also look ahead to view your computer in the intermediate zone. In addition, you can drop your gaze downward to read and do fine work comfortably.
There are many advantages of progressive eyeglasses. One of these advantages is the ability to eliminate an annoying problem caused by bifocal and trifocal lenses known as “image jump.” With conventional bifocals and trifocals, when your eyes move look though the sharply defined borderline between the near and distance parts of the lens you would find that images seem to “jump”. With the help of progressive lenses, you would find the transition between the different lens powers become smooth and seamless, letting you change focus from distance to near and back again more comfortably.
Today’s progressive eyeglasses are easy to adjust to wear. And the costs of the lenses are less and less with the more mature technology. You could try to get a pair of progressive eyeglasses online shops. They sell them at a lower price with the high-quality.
