Every time I go to an optist to get my prescription, I am wondering what those numbers mean. I am sure you may have the same idea with me. Now I have known how to read prescriptions, and I would like to share it with you. Then you can use it to analyze your prescription, especially the complex progressive eyeglass prescription.

No matter how many advantages progressive spectacles have, how advanced they are, we should keep in mind that they are not perfect. Nothing can be perfect. As a matter of fact, there is an inherent problem or shortcoming that will naturally be caused by progressive spectacles. Like other forms of multifocal reading glasses, the problem of peripheral vision loss is to some degrees inevitable. This can not be completely avoided. In fact, it is not objective to singly sing the praises of progressive lenses' unique and sophisticated design.

It is well known that progressive glasses are much better for presbyopia patients. You may also have been one of their customers. However, have you known progressive speciality glass?

It is easy to interpret that a progressive lens's intermediate section will be narrower than that of a bifocal or trifocal lens. All of those claimed benefits of progressive eyeglasses come from the unique lens design which involves a gradient of lens powers. Rather than setting sharp boundary between different lens sections, progressive lenses provide smooth power transition. This means dozens of powers will be included in a single lens. While all presbyopic patients are supposed to get satisfactory visual aids at all distances from a single pair of progressive reading glasses, they may not be satisfied if they need to spend much time in carrying out visual tasks at a certain range. Progressive specialty glasses will do a better job for these users.
