Do you really know anything about progressive multifocus lenses?

     From single focus lens, bifocal lens and now "progressive multi-focus lens", "progressive multi-focus lens" has been widely used in adult anti-fatigue lens, middle-aged and elderly progressive lens and adolescent myopia control lens. So, do you really know anything about progressive multifocus lenses?
1. Progressive multi-focus lenses
Progressive multi-focus glasses are designed to connect the far and near light regions of the same lens in a way of gradual diopter change from the far to the near, so that the different luminosity required for far, medium and close viewing can be obtained on the same lens. Therefore, it can effectively solve the patient's vision needs at different distances of far, medium and near, so as to better visual regulation or compensation.

2. Advantages of lens
1) The appearance of the lens is like a single light lens, without seeing the dividing line of the variation of the degree. It is not only beautiful in appearance, but also can not reveal the age of the wearer.
2) As the lens degree is progressive, there will be no image jump phenomenon.
3) Clear vision can be obtained at all distances in the visual range, and a pair of glasses can meet the needs of far, medium and near distances at the same time.
4) Progressive multi-focus lenses for children can help adjust the eye position of children with excessive implicit oblique and slow down visual fatigue.

3. Applicable people
1) People over 40 years old who wish to see long, medium and short distance vision continuously;
2) Patients with implicit oblique due to excessive regulation;
3) Patients after iOL implantation.

4. Precautions
1) When selecting frames for glasses, the size of frames should be strictly required. Appropriate width and height of frames should be selected according to pupil distance.
2) After wearing glasses, when observing objects on both sides, you may find that the definition is reduced and the visual object is deformed, which is very normal. At this time, you need to turn your head slightly and try to see from the center of the lens, and the above discomfort will disappear.
3) When going downstairs, wear glasses lower and try to see out from the far use area above.
4) Glaucoma, eye trauma, acute eye disease, hypertension, cervical spondylosis and other groups are not recommended.
