symptom
1, visual impairment. This is one of the main symptoms of cataract, which is related to the degree and location of lens opacity.
2, blurred vision, photophobia, darkening or yellowing of the color of the object, and even diplopia (ghost) and object deformation.
3. Sometimes I feel that the aperture around the light and the color of the image are not bright enough. Even when driving at night, I feel that the oncoming headlights are dazzling and uncomfortable.
4. The symptoms of nuclear cataract are mostly lens opacity, which starts from embryonic nucleus and gradually extends to adult nucleus, showing yellow in the early stage, and gradually deepens into dark yellow and dark brown with the aggravation of opacity.
5. Cataract symptoms are bilateral, but the onset of both eyes can be sequential. Its symptoms are mainly progressive vision loss, and sometimes fixed black spots can be seen under bright background.
Matters needing attention
1. Cataract patients should insist on regular eye massage. Eye care of cataract is very important. You can do eye exercises and massage eye acupoints, such as clear eyes, horizontal bamboo, pupil bone, sun and medical wind. Massage can accelerate the blood circulation of eyes, increase immune factors in aqueous humor, improve the immunity of eyeballs, and thus delay the development of lens opacity.
2. Cataract patients should pay attention to protect their eyes, prevent mechanical and radiation damage to their eyes, and educate their children not to play with sharp tools and dangerous toys.
3. Cataract patients keep a good mood. It is necessary to avoid excessive emotional excitement, maintain a good mood, ensure the smooth flow of qi and blood throughout the body, and improve the body's disease resistance.
4. Cataract patients should not feel tired when using their eyes, and pay attention to the correct eye posture, distance and sufficient light source. Every hour or so, let your eyes relax, such as closing your eyes for recuperation, walking, looking at the sky or the distance, etc. Let your eyes have a rest. Try not to work in the dark for a long time.
Pathogenic factor
Cataract is one of the common eye diseases, especially for the elderly.
1. The degree of vision loss of cataract patients depends on the location and range of lens opacity. It is also possible to see the objects in front of you clearly when there is light, but when it is backlit, the eyes of cataract patients will be white, just like a beam of light or sunlight facing your eyes, and you can't see the front clearly. When the opacity is in the center of the lens, myopia occurs at an early stage. When the vision loss affects normal life, surgical treatment is very necessary. Therefore, this is also one of the causes of cataract.
2. There are many causes of cataract, besides traumatic cataract, radiation cataract, congenital cataract and diabetic cataract, there may be many factors in the process of cataract formation.
3. At present, the incidence of cataract is higher in plateau areas and areas with more sunlight radiation in China. Is this because long-term exposure to sunlight and ultraviolet radiation will affect the oxidation of lenses? During the reduction process, the protein degeneration and opacity of the lens form cataracts. These are the main causes of cataracts.
