What are the symptoms of cataracts? What are the symptoms of cataracts

One of the early symptoms of cataracts: blurred vision. People with cataracts have blurred vision, sometimes feeling that there are apertures around the light and that 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.

The second early symptom of cataract: monocular polyopia.

In the early stages of cataracts, the lens is partially cloudy and partially transparent, and light rays cast onto the retina through it produce double or multiple shadows.

The third early symptom of cataract: abnormal color vision.

In the early stage of cataract, due to the swelling of the lens due to the absorption of more water, its epithelial cell gap is enlarged and filled with particulate water droplets, and the light will be refracted when passing through it to present a colored halo, commonly known as iridescent vision.

The fourth early symptom of cataracts: day blindness or night blindness.

If the opacity of the lens starts in the ** part first, when the light intensity and pupil are narrowed during the day, the light enters the eye and is blocked, resulting in day blindness; If the lens is opaque and located in the periphery, the entry of dark light into the retina of the equatorial part is blocked at night, and the rod-shaped optic cells of the retina of the equatorial part of the equatorial retina are specialized in fluid vision, so night blindness will occur.

On **, it is recommended to use traditional Chinese medicine**, and the effect is good.

The main manifestations are progressive visual acuity loss, and other symptoms can be accompanied by decreased contrast sensitivity, refractive changes, monocular diplopia or polyvision, glare, color vision changes, visual field defects and other symptoms.

Cataract in the early stage of cataract may feel that the vision will be a little blurred, sometimes good, sometimes bad, and even sometimes there will be glare, the so-called glare means that when you see the light, it is not a light but a circle. In addition, when the cataract develops to a certain extent, it will cause double vision, monocular double vision, and the severity will be a serious loss of vision, and even in the end, everything in front of the eyes is blurry, and you may only see your fingers shaking in front of your eyes to such an extent.

Cataract is a common disease in middle-aged and elderly people, and the incidence will increase with age. Cataracts can be divided into congenital and acquired. Let's give you a science about the symptoms of cataracts.

1.Symptom 1: Glare is one of the early symptoms of cataracts, when the patient's eyes will lose contrast sensitivity under strong light, and glare will occur under the illumination of car lights at night. There will also be vision loss, and black spots or shadows will appear in front of the eyes of the buried ants in daily life.

2.Symptom 2: Refractive changes are also early symptoms of cataracts, and most of them are symptoms of reduced presbyopia symptoms and increased myopia. In general, in the early stage of cataract, the eyes will have monocular diplopia or polyvision, that is, the things seen overlap.

3.Symptom 3: The opacity of the lens caused by blunt trauma or penetrating trauma and ** injury of the eyeball is called traumatic cataract.

The clouding of the lens caused by radiation is called a radiation cataract. However, clouding of the lens caused by exposure to certain drugs is called toxic cataracts.

Precautions. Cataract patients should eat more fresh fruits in their diet and avoid high-sugar drinks. It is necessary to pay attention to the sunscreen of the eyes, reduce the contact between the eyes and ultraviolet rays, and also pay attention to drinking more water and doing appropriate physical exercise to avoid eye fatigue.
