What are the symptoms that indicate cataracts?

Common symptoms: blurred vision, whitening of the pupils, cystoid macular edema, decreased or absent ocular accommodation.

1.Blurred vision: cataract is mainly caused by opacity of the lens, and patients first present with blurred vision, which can be mild or severe due to the location of the opacity of the lens. Congenital cataracts are mainly manifested by poor vision that cannot be corrected.

2.Shadows: At first, you stumble upon a fixed shadow in front of you that cannot be erased. As blurred vision worsens, dark shadows are not noticeable, but visual acuity is markedly reduced.

3.Myopia: The patient notices that the original reading glasses have become lighter or that they no longer need to wear reading glasses. This is due to crystalline myopia due to the hardening of the crystal nucleus.

4.Monocular polyopia: caused by irregular astigmatism of the lens. Especially when the pupils are relatively dilated in a dark place, such as when looking at the street lamp and the moon at night, it is easy to find.

5.Poor outdoor sunlight and relatively dark indoor vision: seen in nuclear cataracts. Due to the narrowing of the pupils in bright light, the vision is obscured.

In general, the lens of the eyeball is white and cloudy; Subjective perception of distance vision decreases, dark vision is better than light vision, and there may be symptoms such as fear of light, darker or yellow color of objects, and even double vision (double shadow) and distortion of objects.

Objectively observed, the lens of the eye appears white and cloudy; Subjective perception of distance vision decreases, dark vision is better than light vision, and low-grade myopia is formed.

It is mainly blurred vision, and there may be symptoms such as photophobia, dark or yellow color of objects, and even double vision (double shadow) and deformation of objects. The clouding of the lens caused by various causes is collectively referred to as cataract. It can be recuperated by surgery and then with the opening of the pupil, and it will be slowly relieved.

Symptoms of cataract include progressive vision loss, glare, color vision changes, visual field defects, or monocular diplopia or polyopia. Some older people may also show a sudden improvement in their vision. If you have such symptoms, you can go to the hospital for a test before confirming the diagnosis.

Cataracts are generally not visible to the naked eye alone. It is only after overripening that it is possible to see grayish-white reflections from the pupils. The structure of the eye is complex, and there are many eye diseases that cannot be accurately judged by the naked eye based on some symptoms alone.

If you have similar symptoms, it is recommended to go to the hospital for professional examination.

The initial symptoms of cataracts are mainly visual disturbances. In the early stage, the vision is slightly blurred, and it is often not noticeable by itself, and it is only when the binocular vision (distance vision, near vision) gradually decreases at the same time.

Preface: As we grow older, we find that there are more and more problems in our body. This reminds us that we must take care of our bodies, otherwise it will be very painful when we get old.

Cataract is a relatively common disease that occurs more often in the elderly, but it is still very serious if you do not pay attention to your physical condition in life. Let's share with you, what kind of symptoms do cataract patients have?

In the early stages of cataract patients, the gap between the epithelial cells of the eyes increases, resulting in the appearance of microparticle water droplets, and if you look at things, a colored halo appears, and the patient will also have different visual phenomena. If you find that you have abnormal color vision when you look at things, you must go to the hospital to seek medical treatment in time to avoid delaying the early disease and making the cataract more and more serious. We must use our eyes reasonably in our daily life and pay attention to eye rest.

Cataract disease is a disease that occurs in the lens area, patients may have a fixed position, the shape of the same dot or sheet shadow, which is also a very common phenomenon in the early symptoms of cataract patients, if this problem occurs, we must pay enough attention to match a reasonable **, it is still very helpful for recovery. If you don't pay attention, it is likely to cause blindness, so you must go to the hospital and seek medical attention in time. <>

The appearance of the doctor is to solve the incurable diseases of the body, if you encounter various problems, you can go to the hospital to explain the situation to the doctor, and pay attention to some reasonable methods under the doctor's advice, it is still very necessary for the recovery of the eyes. For some of the younger people, we can't stare at a computer screen or a mobile phone screen for long periods of time. Be sure to take reasonable breaks so that your eyes can get enough rest.

Vision may decrease, presbyopia will be relieved, there will be some dark shadows in front of the eyes, some discharge from the eyes, and sometimes it may be painful. You should go to the hospital for surgery, and the effect of surgery for this disease is better.

The vision is relatively blurry, there is no way to see things clearly, the vision is reduced, the lens is relatively turbid, which seriously affects life, and this situation can be carried out by surgery**.

I feel that I have symptoms of weakness in my limbs, dizziness, blurred eyes, lack of sleep, and loss of appetite. And when we encounter this situation, we must go to the hospital**, because this matter is very serious, if it is not timely**, the consequences are unimaginable.

Cataract is a disorder in which the body's lens metabolism is disordered, and the protein degeneration causes cloudiness. Cataract patients will not be able to effectively project light onto the retina due to the cloudy lens, which will make the patient's vision blurred. This symptom is more common in people over the age of 40 and is more likely to occur with age.

1. What are the causative elements of cataract?

According to the clinical situation of cataract patients, cataract can be divided into two types, namely congenital cataract and acquired cataract. Congenital cataracts, also known as developmental cataracts in the medical community, often develop cataracts around birth and may also be accompanied by other genetic disorders.

Congenital cataract can also be divided into two types: endophytic and exophytic, the endogenous type is related to the development of the fetus in the mother's body, and the exogenous type is due to the fetus during development or the mother has caused damage to its lens.

Acquired cataract disease refers to the cloudy symptoms of the lens caused by systemic diseases or local eye diseases, poisoning, trauma and other factors after birth. There are 6 common types of acquired cataracts: senile cataract, concurrent cataract, traumatic cataract, metabolic cataract, radiation cataract and drug-toxic cataract. Among them, senile cataract is more common.

The nature of cataract disease is determined by the location of cataract in the patient's eyeball, and in the medical field, cataract can be divided into three types: nuclear, cortical, and subcapsular according to the location of cataract. A concurrent cataract condition is a condition that occurs as a complication caused by another eye or systemic condition.

Progressive vision loss, which is one of the most obvious and important symptoms of cataracts. Some people may not have as good vision in bright light as they do in low light.

Symptoms such as glare, color vision changes, visual field defects, monocular diplopia or polyopia, and some people may feel that their vision has suddenly improved, and their presbyopia has decreased.

Patients may feel that there is a layer of fog in front of their eyes, that everything is gray and misty, and that they may appear in a fixed position in front of their eyes.

Cataract is a common eye disease, people should take good care of their eyes, and don't let cataract affect your healthy life.

Depending on the type and course of cataracts, the symptoms of cataracts will vary. Cataract is an eye disease in which the lens protein is denatured due to various reasons, and the lens is cloudy and causes blurred vision. It is divided into congenital cataract and acquired cataract.

There are many causes of the disease, such as aging, genetic, immune and nutritional disorders, trauma, etc. The main symptoms are blurred vision, progressive loss of vision, glare, and double vision.

The early symptoms of cataract are blurred vision, such as double vision in one eye, day blindness, and night blindness.

In the case of cataracts in elderly patients, the contrast of objects with similar colors will be reduced and the distinction will be blurred. Some older people with cataracts also experience a decrease in presbyopia.

Patients with cataract should pay attention to it and go to a specialized hospital in time to actively cooperate with the diagnosis and treatment, so as not to delay the condition.

Not all cataracts can damage vision or interfere with daily activities. Some people have mild symptoms that are difficult to detect.

Glare and double vision of lights or sunlight.

Blurred vision, double vision, hazy or hazy.

Glasses need to be changed frequently.

Near vision improves for a short period of time and then gets worse.

Severe cataracts can cause vision loss in middle-aged and elderly people, affecting driving, work, reading, etc.

How does the disease progress after having a cataract?

Cataracts usually don't severely affect vision, and many don't require surgery**.

Cataracts can lead to glaucoma.

As the cataract progresses, more areas of the lens become cloudy. When the entire lens is white, it is called a "mature cataract" and can cause serious vision problems. Blindness may occur in some people, but this is rare.

The vision is not clear, the eyesight is not good, and it is blurry.

Cataract will have distance vision loss and blurred vision, and gradually worsen vision loss, photophobia, tearing and other abnormal symptoms, more severe will appear blurred vision, photophobia, dark or yellow color of the object, etc., if the cataract is very severe, surgery is needed to improve vision. Lighter people can wear glasses.

I can't see clearly, and I feel like something is covering my eyes.

1. Monocular polyopia: the lens is partially cloudy and partly transparent, and the light projected onto the retina through it will produce double or polyphant.

2. Abnormal color vision: due to the swelling of the lens due to the absorption of more water, the gap between its epithelial cells is enlarged and filled with microparticle water droplets, and the light will be refracted when it passes through it and present a colored halo, commonly known as iridescent vision.

3. Shadow in front of the eye: part of the opacity of the lens is located in the pupil area, and there can be dotted or flaky shadows with a fixed position and unchanged shape in front of the eyes. It is distinct from floaters caused by vitreous opacity, in which the shadows are movable, and although they do not have a large range of motion, they appear and disappear and change in shape.

4. Presbyopia is reduced: some elderly people usually need to wear reading glasses to read books and newspapers, but suddenly, they find that they do not need to wear reading glasses to see very clearly, and some elderly people are very happy, in fact, this is not a good sign, this is because when the elderly cataract first appears, the lens convexity increases, and the refractive proximal point changes, which is one of the early symptoms of cataract.
