Age: When should it be a progressive goggle?

Almost everyone is affected by presbyopia
In older age, presbyopia is the most common deficiency vision in humans at 95 percent. Actually, it is not at all a disease, but an age-related loss of function of the eye. Structures in the eye tire in the course of life and close vision as in reading is limited. Many then resort to progressive lenses, some of them, the new visual aid but problems. For them and all those who do not want to wear glasses, there are so-called multifocal lenses. They are used by the ophthalmologist during surgery and restore lost vision.

In presbyopia, the lenses lose their elasticity."They can no longer flexibly adjust to different distances," explains ophthalmologist Dr. med. Robert Loblich from the Artemis Eye Clinic Frankfurt."The point at which images are still being spotted moves ever farther into the distance." Glasses then help to read the fine print again. For many popular progressive lenses, with which both in the near and far range can be seen well. Glasses of these vision aids are ground so that the refractive error is compensated by the upper part of the lens and the presbyopia in the lower part."For many, this is convenient because they only need glasses, but there are also disadvantages," says Dr. Commendable."The brain and eyes need some time to get used to the glasses." This sometimes causes headaches, dizziness, and blurred vision.

In addition, the focus range depends on the viewing direction. People often take their heads back to read texts. This can lead to shoulder and neck pain. When climbing stairs, however, the steps are seen only blurry when looking through the Nahteil the glasses. Studies have shown that when switching to progressive lenses, the risk of falling is doubled. Especially older people with gait insecurity or dizziness should not wear progressive lenses in everyday life.

Anyone who has problems with the progressive lens or who simply disturbs the "nose wheel", can correct the ametropia operatively."Depending on whether corneal curvature, short-sightedness or farsightedness are added to presbyopia, there are various methods", explains Dr. med. Commendable. Lens surgery procedures, such as the insertion of multifocal lenses, give most patients the dream of freedom from glasses. These implanted multifocal lenses work like progressive lenses in the eye and allow sharp vision at different distances. However, since the field of view of the patient is not limited and the distance and near vision is independent of the viewing direction, patients usually have no habituation problems. However, the lenses may sometimes have the disadvantage that stray light can occur at night. In the foreground of the method is to achieve a higher quality of life in everyday life.
