Can cataracts be blind? Can cataracts cause blindness?

Cataract can affect vision and blur vision in mild cases, and blind in severe cases. As the leading cause of blindness worldwide, most cataracts occur naturally due to aging.

Blindness can occur in severe cataracts. Cataract refers to the phenomenon of lens metabolism disorder caused by various reasons, resulting in the denaturation of lens protein and cloudiness, which is a common ophthalmic disease and mostly occurs in people over 40 years old. Cataracts, if left unchecked**, can lead to eye complications and, in severe cases, blindness.

Cataract is mainly surgery, daily care should pay attention to avoid strenuous exercise, wear UV glasses when going out, and control emotions.

Severe cataract can lead to blindness, cataract is a common ophthalmic disease, is currently the first common blinding eye disease in China, is due to the lens inside the eye has appeared cloudy, degeneration, transparency is reduced, resulting in unclear vision, but the blindness caused by cataract is reversible, through surgery to remove the cloudy lens, and then implant a transparent intraocular lens, vision can be improved.

Cataract is the world's leading cause of blindness, and there is a risk of blindness. Whether or not you will go blind is mainly related to the severity of the condition and whether it has been actively and effectively**.

Cataract refers to the clouding of the transparent lens to varying degrees due to various factors. The function of the lens is to clearly reflect the image of the object on the retina through the entry of light when people are looking near or far. If the lens becomes cloudy due to various reasons, less light enters the eye.

The heavier the cloudiness, the less light enters the eye, and the less visible it is. If left unchecked, the patient will become blind when the light is completely blocked.

When you feel that your eyes have decreased vision, blurred vision, and cloudy vision, you should go to the hospital in time for treatment, if you are diagnosed with cataract, because the current diagnosis and treatment technology of cataract is very mature, actively cooperate with **, in order to prevent cataract from developing to the stage of blindness.

A cataract is a vitreous opacity in the eyeball that becomes so severe that you can no longer see objects clearly. Replacing it with a clear and transparent vitreous body can solve the problem. It won't be blinding.

Cataract is a common disease in ophthalmology, which is caused by the clouding of the lens due to various reasons, which leads to varying degrees of vision loss. As the disease worsens, vision may deteriorate dramatically, but no matter what stage of cataract you have, you will not lose sight, and surgery can be used to restore your vision. At present, for cataract, surgery is still the most important way, when the vision loss is more serious, affecting the normal work and life, surgery** can be considered.

The most commonly used surgical method is phacoemulsification aspiration combined with intraocular lens implantation, which has the advantage of being less invasive, so the surgical astigmatism and postoperative reaction are usually mild, and good visual quality can be obtained after surgery. After surgery, antibiotics are routinely used to prevent local infection.

Cataracts have a great impact on vision, and as the condition worsens, it is possible to cause blindness. Therefore, after suffering from cataracts, you should actively go to the hospital for treatment, and actively deal with it through drugs**, surgery**, etc. At present, surgery is the only effective way to treat cataracts, and drugs can only control the condition.

Cataracts can of course cause blindness. And the disease with the highest rate of blindness in our country is cataract. In fact, cataract is currently the disease with the highest blindness rate in the world.

Cataract is a common blinding eye disease that can lead to a variety of complications if left untreated in the middle and advanced stages. Therefore, early detection of cataracts is recommended.

The blindness rate of cataract is very high and should be the highest disease, so if there is a cataract, it must be done as soon as possible**.

Cataracts can lead to blindness in the eyes, so it's best to surgically remove the cataract when it's not severe.

Cataract is currently the world's first blinding eye disease, with as many as 60 million cataract patients in China.

On October 31, 2011, the United Nations confirmed that the world's population has reached 7 billion, of which about 40 million people are blind, accounting for about half of the world's population, half of these 40 million blind people are cataract blind, mainly in developing countries.

In fact, cataract surgery is one of the most common surgeries performed worldwide, with around 10 million cataract surgeries performed worldwide each year.

Cataract is one of the most common eye diseases in the world, with many causes, including congenital and traumatic drugs, among which the most common is caused by advanced age.

Severely, if not **, it can cause dizziness, blurring, ghosting of the eyes.

It's serious. It is advisable to seek medical attention as soon as possible

It's not too serious, just cooperate with **.

The clouding of the cataract lens is called a cataract. Aging, genetics, metabolic abnormalities, trauma, radiation, poisoning, and local malnutrition can cause damage to the lens capsule, increase its permeability, lose its barrier effect, or lead to lens metabolism disorders, denature the lens protein, and form turbidity. It is divided into congenital and acquired.

Congenital cataract: cataract caused by heredity, chromosomal variation, intra-fetal infection, etc.

Senile cataract: It is a phenomenon of aging, with the increase of age, the crystal body will slowly harden, cloudy and cause visual impairment.

As far as is currently understood, the onset of senile cataract may be related to the following factors:

1) Nutrient metabolism: Through animal observation, it was found that the deficiency of certain vitamins and trace elements is related to the formation of cataracts, such as calcium, phosphorus, vitamin E, A, B2, etc.;

2) Sunlight and ultraviolet rays: Under the influence of ultraviolet rays, phosphorus ions may combine with calcium ions in aging lenses to form insoluble calcium phosphate, which leads to hardening and calcification of crystals. At the same time, ultraviolet rays also affect the redox process of the lens, promote the denaturation of lens proteins, and cause cataracts;

3) Outside temperature: foreign scholars have surveyed that the incidence of cataract in workers over 60 years old who work in high temperatures is significantly higher;

4) Hypoxia: In the case of hypoxia, sodium and calcium in the crystal can be increased, potassium and vitamin C can be reduced accordingly, and lactic acid can be increased, which can promote the formation of cataracts;

5) Endocrine: Endocrine disorders can promote the production of cataracts, which is enough to explain that the incidence of cataracts in diabetic patients is higher than that of the general population;

6) Hardening and dehydration: In the case of dehydration, the body fluid metabolism is disordered, and some abnormal substances will be produced to damage the crystals. Animal experiments have proved that after hypertonic dehydration, the crystals appear empty.

There are many cataracts, the most common is degeneration, most cataracts are senile cataracts, this cataract increases with age, the incidence increases, and by the age of seventy, there are nearly 100% cataracts, just like we will have gray hair when we are old, this is primary, basically cannot be prevented or avoided, and it will be operated on. There is also a type of congenital cataract, which is related to genetics and infection during pregnancy. As for the cataracts that occur in young people, most of them are complicated, such as diabetes, rheumatic diseases, high myopia, uveitis, glaucoma, and retinal detachment.

Long-term use of hormones and eye trauma can also cause. Avoiding these causes is also a way to prevent it. Another factor is ultraviolet light.

Hello, cataract is caused by lens aging, genetics, metabolic abnormalities, trauma, radiation, poisoning and local malnutrition, which can cause damage to the lens capsule, increase its permeability, lose its barrier effect, or lead to lens metabolism disorders, denature the lens protein, and form cloudy lesions. Cataracts are divided into senile cataracts, congenital cataracts, traumatic cataracts, and concurrent cataracts.

If the lens of glasses is compared to the glass lens of a camera, then the occurrence of cataracts means that the lens has a ground-glass cloud. As we age, the lens changes for various reasons, causing the lens to become cloudy, blurry vision, and gradually decline vision, which becomes "cataract".
