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 can view articles at far, medium and near distance. In fact, there are tips for wearing progressive eyeglasses. 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.

It is necessary to know the principles of the progressive reading glasses to wear them comfortably. As for a pair of progressive glasses accurately fitted, different regions of the lens have different tasks. For example, those who are wearing the location of the pupil, is used to see long range with the distance degree. Wearer must face to the goal, then look front directly.

The bottom of the lenses is used to see the close regions coupled with the proper degree. When reading or seeing the close objects, the wearers can lean the head slightlky forward and the eyes look down and take the bottom of the lenses to read. It is worthwhile to note that the degrees of refraction on both sides of lenses will change gradually. If only rotates eyes, the wearer will feel that the object is blurred and twisted. In that case, lots of wearers’ eyes are tired easily at the beginning In addition, computer users used to prolonged use of computers and reading documents on the case, close-up demand as large.

Progressive lens eye in close-range is usually narrow, not suitable for such a long time to read generally. If the wearer’s presbyopia degrees are more than 175 and he often needs to watch near objects indoor, a pair of specific progressive glasses which is only for middle and close distances will be a better choice.

Though this pair of glasses frames 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 can be easier to adapt to progressive glasses? Generally, people’s degrees are lower, they are easier to adapt them. When the degree of presbyopia is about 100, you should consider wear progressive glasses, otherwise, you will have a longer adaptation What’s more, myopia people with 200-800 degrees also more easily adapt to progressive glasses. In comparison, longer time is for people slight myopia or hyperopia to familiarize and use progressive glasses.

However, not all people are suitable to wear the progressive multifocal glasses. If the strengths of the two eyes have a big gap, the opportunity of the integration of the two eyes is greater, they will feel fatigued if they use the twp eyes to focus on t You can ask your eye optometrists to assess the suitability of a gradual wearing glasses when think about wearing progressive glasses, further choose the most suitable design according to your degree and use. After fitting, do not forget to adjust the frame's positions frequently because the position deviation will also greatly affect vision correction and visual effects.

First conduct a comprehensive examination of both eyes of the old people before being fitted with the reading glasses. The examination includes distant vision, near vision, dioptric media, fundus, in particular to observe whether there is the cataract, th

• For instance, distance vision above 1.0 and bad near vision can only correct near vision. If distance vision loss is caused by cataract, near vision should be subject to distance vision.
