The elderly have been unable to see clearly recently, how to tell if it is presbyopia or cataracts?

Introduction: There are many elderly people who have blurred vision as they grow older. So if the elderly have a situation where they can't see clearly, how can they tell if they have presbyopia or cataracts? <>

There may be some elderly people who will have blurred vision when they get older, so at this time everyone wants to determine whether it is because of presbyopia or cataracts. If you want to determine which symptoms are, you must first look at the symptoms of presbyopia. In fact, the symptoms of presbyopia are very simple, that is, let them see some things at close range, which will make them feel very blurry, and the eyes will also have some soreness or swelling pain.

After using your eyes for a long time, you may even feel a headache. Therefore, most people with presbyopia will wear some glasses to correct their vision. <>

After seeing this, you may be curious, if you say that the eyes suffer from cataracts, what will be the symptoms. Cataract is actually an eye disease, so if you suffer from this disease, your eyes may become very cloudy. But the middle part of these people's eyes is very transparent, and their vision is very normal.

If the ** is not timely, it may also make these patients' eyesight worse, and even blindness. And their vision will also be particularly blurry, but the eyes. There will be no soreness.

After reading the introduction, I believe everyone has a general understanding of cataract and presbyopia. In the case of presbyopia, the vision will gradually blur, but it will not be invisible. Even if the degree of presbyopia is very severe, blindness does not occur.

However, if you have cataracts, you may become blind. Because it is a disease, there are also cataract patients who can blur even near things. Therefore, everyone must pay attention to their eye health in their daily life, and at the same time, they must also protect their eyes.

Presbyopia also needs to be taken far away to be able to see clearly when reading a book, and the light should be sufficient, and the symptoms of eye swelling and soreness will appear after a long time, cataract is a blinding eye disease, which does not affect vision, the lens lens is only partially chaotic, but the ** part is still transparent, the lens fibroedema and interfibrous fluid continue to increase, so that the vision becomes worse and worse, presbyopia is near can not see clearly, far can see clearly, cataract is not clear anywhere.

If it is a cataract, it will definitely not be able to see clearly, and the eyes are not as good as day by day, and there will be some discharge, and the eyes will feel particularly uncomfortable, but presbyopia will not have such a feeling, but can see some things in the distance clearly.

You should go to the hospital in time to do the corresponding examination to check whether it is presbyopia or cataract, do not use drugs indiscriminately, the symptoms of presbyopia and cataract are different, the reaction is different, the feeling is different, and the method is different, so it is best to go to the hospital for relevant examinations.

Many people confuse presbyopia and cataracts, but what about these two diseases?

What are the symptoms of presbyopia?

Typical symptoms of presbyopia: difficulty seeing near and far.

In contrast to myopia patients, patients with presbyopia will gradually find that they cannot see small characters clearly when reading at close range, so that they unconsciously tilt their heads back or take the book or newspaper to a farther place to read the text, and the reading distance required will gradually increase with age.

Typical symptom 2 of presbyopia: myopia cannot be sustained.

Due to inadequate lens adjustment, the near point gradually becomes farther away, and the patient often struggles to see near objects clearly. If this force exceeds the limit, it will cause tension in the ciliary body. When looking at distant objects, the tension in the ciliary body does not relax immediately, resulting in temporary myopia.

When you look at nearby objects, there will be a brief blur, which is a sign of slow accommodative response. Fatigue occurs when the ciliary muscles are functioning close to their functional limits and are unable to work continuously.

Because of the decreased accommodative power, the patient has to work close to the limit of binocular accommodation, so it cannot last too long. At the same time, due to the linkage effect of the adjustment sleeve, excessive adjustment will cause the sleeve to be too heavy, which is also a factor causing discomfort. So it's easy to read the newspaper **, the handwriting is in pairs, and in the end you can't read it.

Some patients may even experience symptoms of eye fatigue such as eye droppings, watery eyes, headaches, and itchy eyes.

Typical symptom 3 of presbyopia: Reading requires stronger light.

Lack of light not only increases the visual discernment threshold, but also dilates the pupil and forms a large circle of diffusion on the retina, making the symptoms of presbyopia more pronounced. As they get older, they tend to get tired even when working in close proximity during the day, so people with presbyopia like to use brighter lights when reading at night. Sometimes the light is placed between the book and the eye, both to increase the contrast between the book and the text, and to reduce the pupils.

However, the light in front of you will inevitably cause glare interference. The closer the light source is to the eye axis, the greater the impact on vision.

Is presbyopia a cataract?

Presbyopia is not a cataract, it is a two-disease disease.

Presbyopia] can't see things around you clearly, but things in the distance are much clearer;

Cataract] Whether you see far or near, you can't see clearly, like your eyes are covered with gauze. Cataracts, if left unchecked**, can lead to other eye diseases such as glaucoma. In addition, cataract and presbyopia also differ in the degree of harm and the best method.

Presbyopia] may cause eye strain, blurred vision, and may be accompanied by symptoms such as swollen eyes and headaches. However, presbyopia generally does not cause other eye diseases.

Cataracts] can seriously affect the quality of life of patients. If left untimely**, it can trigger other eye diseases such as glaucoma. As the condition worsens, vision gradually decreases, which can eventually lead to blindness.

Presbyopia can't see things clearly, and things are blurry, and presbyopia is the inability to see things at close range, which is more blurry. Presbyopia is not caused by cataracts, but by the deterioration of the ability of the ciliary muscles to adjust.

Presbyopia can be seen in the distance, but it is not clear when looking at the near place, usually occurs around the age of 40, and generally speaking, it is more obvious over the age of 45. Cataracts are usually found in people over the age of 60, and if they occur, they are not clear whether they can see far or near.

The symptoms of presbyopia are blurred vision, there are often some headaches, and presbyopia is not a cataract, so some people don't have to worry.

If you have a cataract, your eyes will turn white, but no, your eyes will look cloudy and yellow. The details are as follows:

1. The vision is getting blurred and blurred.

This is a common symptom of cataracts*, and you usually see things vaguely, and you can't see things clearly and directly.

2. Look at things darkening.

It feels like there is a dark shadow or double vision in front of you, and the color becomes darker.

3. Sudden relief of presbyopia.

Many elderly people usually need to wear reading glasses to see things, but suddenly their presbyopia is relieved, and they can see clearly without wearing glasses. But in fact, this is one of the early symptoms of cataracts, and the sudden relief of presbyopia is due to an increase in the refractive index of the lens and a change in the refractive proximal point.

4. Day blindness or night blindness.

Day blindness and night blindness also need to be paid attention to, which is also one of the early symptoms of cataracts. Day blindness is defined as having worse vision in bright light than in dark; Night blindness, on the other hand, is worse in the dark or in the darker than during the day.

The vast majority of cataract onset occurs slowly. In the early stage, you can not feel anything, neither red nor swollen, only feel that there is white fog in front of your eyes, you can't see fine things clearly or see things that are deformed and bent, and gradually develop to the point that double shadows will also appear when you see in one eye, and more importantly, you can't use lenses to correct it. In some elderly people, due to the increase in lens density and refractive power, the original power of old light decreases and becomes temporary myopia.

There are also nuclear cataracts that have good vision in cloudy or dark places, but they cannot see clearly under strong light, because the dark outer pupil is larger, and the light enters the eye through the transparent part to feel clear vision. If cataracts are caused by eye trauma, sudden loss of vision can occur. In less cataracts, when the disease progresses, the lens absorbs water and increases in size, causing pupillary block, and the aqueous humor cannot flow out normally, resulting in an increase in intraocular pressure, which is medically called "secondary glaucoma", at this time there will be severe eye pain, headache, nausea and vomiting and other complications.

1. ** sexual and gradual visual decline: vision gradually declines, and in severe cases, you may only feel light.

2.Photophobia: Sensitive to music, even very eye-catching and photophobia, especially at night.

3.Color error: Sensitivity to color is reduced, and objects seen are often yellowish or dark.

4.Film-covered eye: This is the sensation of a thin film covering the eye.

5.Monocular diplopia: There is often the feeling of seeing one object as two images.

6.Refractive changes: Glasses often need to be changed in order to restore normal vision.

7.Rainbow vision: When the eye looks at a light that is on, a rainbow-like halo appears around the light source.

Summary. Hello, there are many reasons for the elderly to see clearly, most of the elderly vision decline is considered to be caused by age-related cataracts, there may be no obvious changes in the early stage, when the lens is cloudy to a certain extent, there will be double vision, double vision, and significant vision loss, consider cataract surgery**. There are many reasons, such as refractive error, most of the elderly show farsighted astigmatism, usually need to be corrected for refractive error, vision can also be significantly improved, such as keratitis, glaucoma, fundus optic nerve or macular disease, etc., it is best to go to the hospital eye clinic for a detailed examination.

Especially for the elderly with a history of hypertension, diabetes, and hyperlipidemia, it is best to go to the hospital for regular check-ups to prevent various complications of the fundus from causing vision loss.

Can cataracts be cured by surgery?

Yes, the surgery can be good.

End of consultation.

If you can't see clearly, you need to check whether it is a vision problem or something else, and other problems, including cataracts, can only be determined by diagnosis.

Whether it is a cataract or not needs to be confirmed after examination. Common symptoms of cataract are: blurred vision, double vision, abnormal color vision, day blindness and night blindness.

Not necessarily, cataracts, floaters, blurred vision, etc. Go to the hospital to check, the elderly are better checked.

The initial symptoms of internal cataracts are mainly visual impairment. In the early stage, the vision is slightly dim, and it is often not noticeable by itself, but the binocular vision (distance vision, near vision) gradually decreases at the same time, and it is only when the vision is reduced to a certain extent that it is not noticed. Middle-aged people should pay attention if they have mild visual impairment, or if they have easy eye fatigue, or if they have black spots in front of their eyes and they are fixed, or if they have clouds in front of their eyes, their vision is blurred, or they have double vision (double vision).

If you have cataract, the original presbyopia will be reduced, and you must go to it in time if you have cataract, usually using eye drops that specialize in cataract. The obvious symptoms of cataract are blurred vision, foggy sensation, abnormal color vision and other symptoms. Monocular diplopia, photophobia, black spots in front of the eyes, blurred vision, glare, poor color discrimination, gray and dark vision, and the late symptoms are visual impairment.

The early symptoms of cataract include blurred vision, color change, photophobia, black spots in front of the eyes, diplopia, crystalline myopia, etc., while the late symptoms are the deepening of visual impairment, which can only distinguish fingers in front of the eyes or only the sense of light remains, until the final blindness, and the whole development process is slow. However, even when people are blind, they still have a sense of light, that is, they can distinguish between day and night.

Older people who suddenly have blurred vision should have their blood sugar checked.

Fundus microangiopathy is one of the 4 major chronic complications of diabetes. Some older people begin with diabetes, which may be asymptomatic or mild, but the comorbidities or complications are very serious, and sometimes precede the symptoms of diabetes or appear as the main symptoms, thus masking the symptoms of diabetes itself. This is because the patient's own insulin secretion function decreases, resulting in disorders of sugar, protein, and fat metabolism in the body, and the metabolic function of the whole body is dysfunctional.

The eye is a very delicate and sensitive organ, and abnormal changes such as brittleness, hardening, thickening of the tube wall, and narrowing of the lumen of the fundus are enough to cause different degrees of fundus hemorrhage, resulting in vision loss and even blindness.

Therefore, if the elderly suddenly find myopia or farsightedness, and have symptoms such as blurred vision, drooping upper eyelids, frequent boils and swelling of the eyelids, eye redness, eye pain, etc., do not think that it is only an eye disease or a normal aging phenomenon, and ignore the blood sugar diagnosis of diabetic fundus lesions. It is important to know that farsightedness and blurred vision caused by aging occur slowly and not as abruptly as diabetes complications. For this reason, I would like to remind the elderly friends who have been suffering from diabetes for many years that even if you have taken a strict diet and medication**, do not forget to check the fundus for lesions frequently, and once you find signs of bleeding, you should perform laser** as soon as possible to seal the bleeding area of the fundus and protect your vision.
