Nowadays, more and more people know the progressive eyeglasses, and many people wear them. In order to wear a comfortable progressive glass, we are not only getting the knowledge of progressive lenses, but also need to learn what frame to best choice for these kinds of plastic lenses.
Progressive glasses, also called Progressive Addition Lenses (as PAL), or no-line bifocals, are used in to correct presbyopia and other disorders of accommodation. Because of they have a gradient of increasing lens power, added to the wearer’s correction for the other refractive errors. As distance area at the top of the lens reaches a maximum value, or as the reading area at the bottom of the lens has the full reading addition. The middle of lens is the intermediate area with the gradient power.
With progressive eyeglasses, the wears will not easily feel tired. It is very effective to reduce myopia. And, especially for the teenagers, they do not need to worry about their growing myopia length. If you first wear progressive eyeglass, it is recommended that you choose a larger frame type (height is not less than 28mm), which could help you get the more of the lens for the three prescriptions parts. It means that a bigger frame comes with a bigger lens. Therefore, allow your eyes to have more areas to get used to the three Rx powers. And, larger frame with the moveable nose pads is the best choice for progressive eyeglasses. Sometimes, people could self-adjustments the nose pads to feel comfortable while wearing these kinds of eyeglasses. If you find the near segment (reading zone for near) is a bit lower than you expected, please push the nose pads slight closer to raise the eyeglasses. Meanwhile, if you find the near segment (reading zone for near) is a bit higher than your expectation, please push the nose pads apart slightly to lower the eyeglasses.
The plastic frames couldn’t get the above effect. The reason is the nose pads of plastic frames are unmovable, and people are difficult to self-adjust nose pads to adapt the progressive eyeglasses. Of course, some people have allergy for metal frames or special like plastic frames, at recently, some prescription glasses online websites could supply the plastic frame with the movable nose pads. In all, it completely helps people could have multiple choice.
