In recent years, many people who are suffering from presbyopia have selectively matched progressivel glasses, for it can continuously provide different focuses on one lens. Therefore, the wearers need only use a pair of glasses so that they can see objects which are far, middle and near distances. Actually, there are some keys to wear progressive glasses. Progressive eyeglasses for many people are convenient, but there are a lot of people who first wears at the beginning feeling a bit difficult to adapt to.

In order to wear comfortably, it must know the principle of progressive optical first. Generally, a pair of progressive glasses fit precisely is designed with specific functions in different lens areas. For example, the alignment of the location of the pupil, if it is used to see distant objects, it should be accpmpained by the proper degree, if the wearers want to clearly see the distant objects, they should face the goal first and then look forward.

Below the lens where there is used to see close-regions, coupled with a low degrees. When reading or watching near objects, your head may have a slight forward lean, and keep your eyes looking down when reading books in bottom of the lens. Moreover, please note that, due to the change of refractive degree on both sides of lens, once wearer simply turn left and right eye, objects through there will be blurred or distorted. This is also the cause of wearers easily feeling eye fatigue at the b Besides, computer users are used to prolong to use computers or read the documents by computers, there is high requirement to look at middle, near distance.

The middle and close range seen from common progressive lenses is usually narrow, so they are not suitable for reading a long time. If the wearer reaches 175 degrees at presbyopia or above, and also often need to watch nearly indoors, he can consider fitting a pair of progressive lens dedicated for middling and close quarters.

Though this pair of eyeglasses can not be used to look at forane objects, but it has been designed with a wider optical zone and the effect will be more satisfactory. Who would make it easier to adapt to progressive lens do? In general, the old flowers degree shallower, the more easier to adapt. Presbyopia about 100 degrees, you should consider wearing a progressive lens, or in the future will be a longer adaptation pe People who myopia of about 200-800 degrees will also be easier to adapt. Comparatively, only a slight myopia or hyperopic some people, they need more time to familiarize themselves with the use of progressive lens.

However, not everyone is suited to wear a progressive lens. If the big gap between the two degrees, there are have many problems about two integration capacities, and then people will feel tired when the eyes focus on something. When fitting the wearer progressive glasses, you can ask for advice from your optometrist to assess whether you are suitable for a gradual wear glasses, and selecting the most appropriate design regard to your degree and the function that fit you. Don't forget to check after the match is often frame position, because position deviation will greatly affect vision correction effect and vision.

Additionally, for old people, above all, there should be a comprehensive examination of both eyes, including distance vision, near vision, refractive stroma, fundus, in particular to observe whether suffering cataract, glaucoma, or retinal disease.

If the distant vision is more than 1.0 while the near vision is low, it only needs to correct the near vision. If the distant vision decreases because of cataract, the near vision degree should abide by the measured distant vision when correcting.
