Cataract: basics and causes
What exactly is a cataract? How dangerous is this eye disease? More in this chapter.
The cataract is a collective name for eye diseases in which there is a clouding of the lens. Medically the cataract is called cataract. Left untreated, it can lead to blindness.
According to the Professional Association of Ophthalmologists, half of the German population between the ages of 52 and 64 develops clouding of the eye lens. However, not all people with such a "cataract" notice visual disturbances.
A cataract or cataract is any form of lens opacity. This can come for a variety of reasons and in principle at any age. Often the causes remain unknown.
The most common cause is simply a higher age. Because with increasing age, the metabolic activity of the eye lens decreases slightly. And that can eventually lead to lens opacity, so the cataract.
No. Strain of the eyes affects the muscles and nerves in this area, which can lead to headaches, among other things. But not the eye lens, which is usually clear and thickening and clouding in the cataract.
A cataract caused by thermal radiation is explicitly recognized as occupational disease (BK No. 2401: "Cataracts due to heat radiation"). This special form of cataract is also known as heat star, infrared star, Feuerstar or Glasbläserstar.
