Are cataracts contagious, and can cataracts cause other conditions when they occur?

Cataracts are crystal protein degeneration, degenerative lesions, unrelated to germs, and non-contagious. After the onset of one eye, the disease of the other eye is also followed soon (unless traumatic), and the disease occurs in both eyes, not necessarily at the same time.

Cataracts are not contagious, but they are hereditary.

Selenium is extremely important for the function of the visual organs. Selenium protects the cell membranes of the eye by catalyzing and eliminating free radicals that are harmful to the eye. If the human eye is in a state of selenium deficiency for a long time, it will affect the integrity of the cell membrane, resulting in vision loss.

and the occurrence of many eye diseases such as cataracts, retinopathy, night blindness, etc. At present, hospitals in some large cities have carried out selenium for patients with eye diseases, and clinical studies have shown that selenium does have a significant effect on improving vision, and can lead to cataracts and retinopathy.

and other eye diseases.

Selenium Weikang Chewable Tablets have a strong antioxidant effect, which can remove excessive free radicals and prevent cataract diseases.

No. Don't be afraid.

Heal well. It's just a minor illness.

No, it is generally caused by not protecting your eyes when you are young, and later eye diseases are caused by the current medical technology and the development of patience**!!

After cataracts, they do not cause other diseases, the most common is increased intraocular pressure, which affects vision. The worst outcome is blindness, and everything else is fine. Therefore, this is also a problem that cannot be ignored and must be dealt with in a timely manner.

After cataracts occur, if not timely**, it will gradually progress to eye blindness.

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.

Due to the limitations of technology and the lack of intraocular lenses, cataract surgery in the past often waited until it was "mature", but in fact, the degree of cataract sclerosis in maturity will increase, so more ultrasound energy is required in the operation, which increases the risk of surgery.

In addition, overmature cataracts may increase the risk of iris inflammation, glaucoma, and lens displacement.

Cataracts may present with amblyopia or secondary glaucoma. Therefore, if there is cataract, it must be carried out actively and effectively to avoid these complications. Cataracts are often caused by opacity of the lens, and are generally divided into congenital cataracts and acquired cataracts.

Congenital cataract is not actively carried out**, and it is likely to develop form-deprivation amblyopia. Therefore, it is necessary to take the child to the hospital as soon as possible and have cataract correction surgery as soon as possible.

In the case of acquired cataracts, surgery is often required as soon as possible during the expansion period**, and if surgery is not performed at this time, secondary glaucoma is likely to occur. At this time, the eyes will have a feeling of swelling and pain, and the patient is often more painful, so although cataract is not a major disease, it should be carried out as soon as possible**, and the current cataract surgery ** is still very mature.

In the development of cataracts, if not timely, there will be many serious complications, such as glaucoma, pigmentitis, etc., these eye diseases mostly occur in the middle and late stages of cataracts, such as swelling and overmaturity, which can not only cause blindness, but also sometimes cause severe inflammation in the eye, resulting in eye atrophy; Some patients may be unable to tolerate long-term eye pain and eventually have to undergo enucleation. Therefore, everyone is reminded that cataracts have progressed to a certain level and must undergo surgery**.

People who are prone to cataracts mainly include: the elderly, people who often work in the sun, and people who do not like to eat vegetables and fruits.

The human body is called cataract when the human body causes lens metabolism disorders due to various reasons such as aging, heredity, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., resulting in the degeneration of lens proteins and cloudiness.

Cataracts are indeed more common over the age of 40, and the incidence increases with age. However, cataracts, like other "geriatric diseases", tend to be younger and younger.

The reason for this is that age is not the cause of cataracts, but the "aging" of the lens.

The causes of lens aging include genetics, nutrient metabolism, endocrine, ultraviolet rays and other factors.

However, due to the high pressure of life, irregular work and rest, young people have been staring at electronic devices such as computers, mobile phones, iPads and other electronic devices for a long time, and it has long been a cliché to have eye health problems such as cataracts.

Some elderly people are prone to cataracts, if they are exposed to some radiation for a long time, they are also prone to cataracts, some patients with high myopia or glaucoma are indeed prone to cataracts, and of course, diabetics are also prone to cataracts. Therefore, these high-risk groups should go to the hospital regularly for follow-up check-ups to see if there are cataracts in their eyes.

Older people are the most likely to get cataracts. People over the age of 70 or 80 have a higher chance of getting cataracts. It can account for about 80%. There are also people who work outdoors all year round.

Generally, older people are particularly prone to cataracts, and people will get cataracts when they reach a certain age.

Cataracts are no longer a "disease of old age", and many young people are now wearing cataracts. According to the survey, the age of onset of cataracts has been reduced from fifty or sixty years old to thirty or forty years old. The incidence of cataracts has become more and more "younger", and its occurrence is related to the bad habits of young people nowadays.

So who is susceptible to cataracts?

1. Patients with high myopia.

In recent years, there has been a significant increase in the number of young patients suffering from cataracts due to high myopia. Cataracts caused by high myopia are called nuclear cataracts. The main features of this cataract are nuclear opacity and posterior capsule opacity.

As the disease progresses, the color of the lens gradually changes from brown to brown or black.

2. Mobile phone party.

Nowadays, mobile phones have become an indispensable part of the lives of many young people. Some people can look at their phones for 6 to 7 hours a day. Spending a lot of time on your phone can greatly increase your risk of developing cataracts.

Some studies have found that cataracts are associated with high-frequency blue light radiation emitted by mobile phone screens.

3. White-collar workers. White-collar workers need to work long hours in front of the computer and use their mobile phones for entertainment after work. The radiation from these electronics is harmful to the human eye. If this bad habit persists for a long time, it is easy to develop eye fatigue and cause eye diseases such as myopia, glaucoma and cataracts.

4. Older people.

The incidence of cataracts increases with age, and the age of cataracts is related to the age of the patient. Therefore, middle-aged and elderly people should have regular physical examinations to protect their bodies.

Cataracts are mostly elderly, but cataracts are not a disease specific to the elderly. The high incidence of cataracts is in the elderly, because cataracts are part of the aging of the body. As people age, all aspects of their body begin to weaken, and the function of the lens is also relatively weakened, so the chance of developing cataracts increases.

People who have been exposed to ultraviolet rays for a long time are more likely to develop cataracts because the ultraviolet rays in the sunlight cause more damage to the lens.

The susceptible people to cataract include: 1. The elderly over fifty or sixty years old, this kind of cataract is called senile cataract; 2. In newborn children, this kind of cataract is called congenital cataract; 3. For people with eye injuries, this kind of cataract is called traumatic cataract, which has nothing to do with age; 4. People with diabetes or long-term use of hormones, this kind of cataract is called secondary cataract, and it has nothing to do with age.

The appearance of cataracts is age-related, that is, as we age, the lens becomes cloudy. Statistics now show that many people in highland areas are prone to cataracts due to exposure to ultraviolet light. There are also people who work in radiation, and if they do not pay attention to protecting their eyes, they are often exposed to radiation, and some patients have arthritis, kidney disease or diabetes, because these diseases require hormones, which can easily lead to cataracts.

Cataract is a geriatric disease, most of which occur in the elderly, and the elderly with diabetes are more likely to get cataracts.

High intraocular pressure Glaucoma is prone to cataracts.

Anything that can cause the lens to be cloudy and the vision is not clear, it can be called a cataract. Cataract has a high incidence in middle-aged and elderly people, and it is extremely harmful. Many middle-aged and middle-aged friends who have cataracts are very distressed about whether they will inherit it to their children.

Cataracts are classified as congenital and acquired. Acquired cataract is the cataract formed by the aging of the lens with age, which is often referred to as senile cataract, and acquired cataract is produced by everyone and is not hereditary. Congenital pediatric cataract will be inherited, and if there is a family history of congenital cataract, the child will have a greater chance of inheritance.

Congenital cataract mostly exists before and after birth, a small part is gradually formed after birth, mostly hereditary diseases, there are two types of endogenous and exogenous, endogenous and fetal development disorders, exogenous is caused by damage to the lens caused by maternal or fetal systemic lesions.

Congenital cataract is hereditary, and congenital cataract refers to the cataract caused by a congenital genetic or developmental disorder that exists around the time of birth, or gradually develops within one year of birth.

Generally speaking, cataracts are divided into several types: senile, concurrent, congenital, traumatic, metabolic, drug and toxic, and posterior. None of these types are due to infection, and no cases of cataract infection have been detected so far.

In recent years, it has been found that sunlight is involved in the formation of cataracts, and temperature also has a certain impact on the incidence of cataracts. Avoid strong sunlight and wear sunglasses or a hat when outdoors to prevent damage to the crystal.
