The high incidence of cataracts affects people in various countries and regions around the world. According to research and investigation, cataract has become an important factor that harms human vision health, causing vision disorders or insomnia. The overall incidence is more than 20%.
With various types of information technology
And the popularization and wide application of digital products, etc.
Children with eyes and entertainment methods
There have been tremendous changes

What is the disease of cataract?
We can see that the outside world is because the light passes through the corneal, crystal, and vitreous body from the outside world, and then focuses on the retina, and then transmits the signal to the brain through the optic nerve. In this process, problems may affect our visual quality. Essence
The eyes need to be kept like a camera so that you can see things at different distances. The zoom lens in the eyes is crystal. The eyeball will make the crystal thinner or thicker through the ciliary muscles, so that things from afar and nearby can be seen clearly.
Under normal circumstances, the crystal is colorless and transparent, but due to various reasons such as age and trauma, the transparency of the crystal body is reduced, and the color changes will cause the visual quality to decrease. This is cataract. In short, cataracts are “old”, broken, opaque, and unpleasant.
Cataracts are divided into congenital, seniority, metabolism, trauma, etc. Among them, older cataracts are the most common.
Black shadow heavy shadow, flying mosquito disease is not cataract
Cataract can indeed cause symptoms such as black shadows, heavy shadows, and blur vision, but flying mosquitoes are not symptoms of cataracts!
In addition, not all black shadow heavy shadows and visual ambiguity are caused by cataracts. For example, middle -aged and elderly people, especially patients with hypertension and diabetes, have black shadows, mosquito and visual vagueness. Retinal vein obstruction, diabetic retinopathy, etc.).
Therefore, patients with eye discomfort are recommended to go to the hospital for screening and early treatment as soon as possible!
Can cataracts be treated with medication?
Many elderly people may be afraid of surgery and are more willing to choose drug treatment. There are many drugs that treat cataracts, including antioxidants such as sulvon, amino acids, aspirin drugs such as taurine, etc., but the effect is not very optimistic.
Specific to the human body, so far, there is no drug in the world, which has proven to be effectively prevent or treat cataract.
What is the correct way to treat cataract?
At present, the only effective way to treat cataracts around the world is surgery, which is the consensus of global ophthalmologists. The 8th edition of “Eye Science” said: At present, more than ten kinds of anti -white intra -barrier drugs including Chinese medicine are used in clinical practice, but their curative effects are not very accurate.
The China Health and Health Commission’s China Defense Blind Blind Website said: No matter what cataracts, surgical treatment is the most effective means. So far, no drug has been proven to cure white internal barriers or prevent the development of cataracts.
Therefore, if you find cataracts, go to a regular hospital for surgery in time.
At present, the mainstream surgical method is “ultrasonic emulsification cataract removal combined with artificial crystal implantation”, which is simply an ultrasonic emulsification of turbid cataracts, then sucks out, and then loads an artificial crystal. If most people have no other problems with their eyes, the crystals they choose are suitable, then the vision after surgery can be recovered well.
When the elderly have the following symptoms, they should be alert to whether they have cataracts.
Visual vagueness: The definition of things decreases, and gradually worsen, especially at night.
Glare: It is difficult to see the objects in strong light, and it is aperture to see things.
Review: When you look at things with one eye, there is a heavy photo.
Change: Seeing things feel dark, yellowish or brown.
