What are the symptoms of cataracts? Does it matter? As the title suggests, thank you

Symptoms of cataracts: Monocular polyopia: In the early stage of cataract, the lens is partially cloudy and partially transparent, and light rays are projected through it to the retina to produce double or polyphance.

Abnormal color vision: abnormal color vision, in the early stage of cataract, due to the swelling of the lens absorbing more water, its epithelial cell gap is enlarged and filled with particulate water droplets, and the light will be refracted when passing through it and present a color halo, commonly known as rainbow vision. Blurred vision:

Blurred vision, gradual blurring of vision, sometimes the appearance of an aperture around the light and the color of the object is not bright enough. If you drive at night, you will feel uncomfortable or irritated by the headlights of the car coming from the opposite side. In general, however, the process of symptom development is quite slow and depends on where the lens is most cloudy and how it develops.

Presbyopia reduce: 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, some elderly people are very happy, in fact, this is not a good sign, this is because when the elderly cataract is first onset, the lens convexity increases, and the refractive proximal point changes, which is one of the early symptoms of cataract. Day blindness or night blindness:

Day blindness or night blindness, if the lens opacity starts in the ** part first, when the light intensity is strong and the pupil is narrowed during the day, the light enters the eye and is blocked, so the day blindness occurs; If the lens is opaque and located in the periphery, the dark light entering the equatorial retina at night is blocked, and the rod-shaped optic cells of the equatorial retina are specialized in fluid vision, so fluid blindness will occur. Shadow in front of the eye: In the early stage of cataract, part of the lens is clouded in the pupil area, and there can be punctate or patchy shadows in the front of the eye with a fixed position and unchanged shape.

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.

In fact, it is normal for the elderly to have cataracts, they just don't see much clearly at the beginning, and if they are treated in time, they will get better, so don't worry too much. You can use those big brands of eye drops that specialize in cataract treatment, such as Shapu Aisi eye drops, to ** cataract, and usually eat more vegetables and fruits. I hope your grandpa gets better soon!

1 Cataract is a degenerative change in the optical quality caused by the loss of transparency of a structure in the eye called the lens, or a change in color. The pathogenesis of cataract is complex, which is the result of the long-term comprehensive effect of various factors inside and outside the body on the lens. The lens is in the intraocular fluid environment, and any factors affecting the intraocular environment, such as aging, genetics, metabolic abnormalities, trauma, radiation, poisoning, local nutritional disorders, and some systemic metabolic or immune diseases, can directly or indirectly damage the tissue structure of the lens, interfere with its normal metabolism, and cause the lens to undergo turbidity plexus fibrillation.

2 The main symptoms of cataract are:

Clause. 1. Vision loss, which is the most obvious and important symptom of cataracts.

Clause. Second, the contrast sensitivity decreases, especially in cataract patients at high spatial frequencies.

Clause. 3. Change in diopter. Nuclear myopia occurs in nuclear cataract due to the increase in the lens and refractive index, and the increased refractive power of the lens.

Clause. Fourth, monocular diplopia or polyopic lens turbidity or water gap formation, so that the refractive power of all parts of the lens is uneven, similar to the effect of prism, resulting in monocular diplopia or polyopia.

Clause. 5. Glare.

Clause. 6. Changes in color vision.

Clause. 7. The visual field will not be defected to the same degree.

3. If cataract is diagnosed, surgery is generally used, and now the surgical method is generally, phacoemulsification of cataract plus intraocular lens implantation, if it is a simple cataract, there is no other disease of the eye, such as glaucoma, diabetic retinopathy, hypertensive retinopathy, retinal ** vein occlusion, the effect after surgery is generally better.

4. For cataracts, the way to remove the cataract is surgery, and the drug generally has no sexual effect. In the early stages of cataracts**, drugs have the effect of controlling the condition. However, in the case of advanced cataracts, drugs have little effect.

And at present, there is no specific drug for cataract, surgery is the best choice, and the commonly used cataract surgery methods are:

1. Cataract capsular extraction; 2. Phacoemulsification surgery for cataracts; Modern extracapsular cataract extraction combined with intraocular lens implantation has become the most widely used surgical method, and it is also a relatively mature surgical method.

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.
