Many people think that cataracts are for the elderly, and most people have a certain misunderstanding of this disease. For cataract surgery, it is even a very scary thing to operate on the eyes, and psychologically, they think that they must not operate on their eyes as a last resort. In fact, with environmental changes, ultraviolet radiation, overuse of eyes and visual fatigue, eye diseases are showing a trend of younger onset. The correct understanding and scientific leadership have become a long way to go for ophthalmologists. Do cataracts manifest as blurred vision? Many people find that their blurred vision affects their normal life before they go to ophthalmology to clearly diagnose what causes it and whether it is a cataract. However, generally speaking, blurred vision can be caused by many reasons, such as inflammation, infection, long-term refractive error, glaucoma and so on. The blurred vision caused by cataract is due to the disorder of lens metabolism caused by the aging of the eye with age, local nutritional disorders, immune and metabolic abnormalities, long-term ultraviolet radiation, etc., resulting in the clouding of lens proteins due to degeneration, at which time the light is blocked by the clouded lens and cannot be projected on the retina, which only leads to blurred vision, and this condition is what we call cataract. This is a condition we call cataract. It is most common over the age of 40 and its incidence increases with age. If we look at it more vividly, it means that there is a rock-like thing growing in the middle of the eye. From the initial feeling that there is a layer of hairy glass on the top of the eye, then it will feel like the eye is covered with a thick layer of “curtain cloth”, completely blocking the communication channel between the eye and the outside world. Prevention In terms of prevention, with the change of lifestyle and life rhythm, the age of onset of the disease spectrum is also showing a younger performance. Poor lifestyle leads to nutritional disorders of the eyes and excessive radiation exposure, which directly leads to the trend of younger onset of cataracts. Nowadays, a considerable number of young and middle-aged people are working and entertaining in front of computer screens. Due to the damage of electronic radiation for a long time, the crystal tissues in the eyes gradually lose their original functions and metabolic balance, resulting in crystal turbidity, which leads to cataract diseases. Some clinical surveys also show that fast food diets cannot meet the nutritional needs of the eyes, and excessive consumption of fast food by people with urokinase deficiency can cause eye lens lesions and accelerate the production of cataracts. In addition, unhealthy lifestyles such as addiction to smoking, alcoholism, excessive eye use and lack of sleep time can lead to subhealthy eye structures, causing crystalline protein lesions and inducing cataracts. Therefore, we still need to advocate healthy eye use and scientific eye use to minimize the triggering factors of eye diseases, and if there are symptoms of sudden vision loss, we should go to the hospital for examination and get effective treatment in time.
