Cataracts, as they are commonly called, are a common eye disease that seriously affects people’s normal life. For the elderly, as they age and their body functions continue to weaken, the chances of cataracts increase, with early cataract patients experiencing a significant loss of vision and later leading to blindness. The cataract patients will have a significant loss of vision in the early stage, and in the later stage it will lead to blindness.
In recent years, the incidence of leukodystrophy has been on the rise, causing problems in the lives and health of many elderly people. The onset of senile leukodystrophy may be related to the following factors.
1, Nutrient metabolism Through animal observation, it is found that certain vitamin and trace element deficiencies are related to cataract formation, such as calcium, phosphorus, vitamin E, A, B2, etc.
2.Sunlight and ultraviolet light Over the years, it has been noticed that sunlight is involved in the formation of human cataracts. Under the influence of UV light, phosphorus ions may combine with calcium ions in the aging lens to form insoluble calcium phosphate, which leads to the hardening and calcification of the crystal. At the same time, ultraviolet light also affects the redox process of the lens, prompting the denaturation of lens proteins and causing cataracts.
3.External temperature Foreign scholars surveyed the incidence of cataract in workers over 60 years old who work under high temperature is significantly higher.
4.Lack of oxygen Under the condition of lack of oxygen, it can increase sodium and calcium in the crystal, reduce potassium and vitamin C accordingly, and increase lactic acid, which will prompt the formation of cataract.
5, endocrine endocrine disorders can contribute to the generation of cataracts, as illustrated by the higher occurrence of cataracts in diabetic patients compared to the general population.
6.Hardened dehydration When human body is dehydrated, the metabolism of fluid in the body is disturbed, and some abnormal substances will be produced to damage the crystal. Animal experiments prove that after giving hypertonic dehydration, the crystal appears empty.
