What are the causes of vision loss in middle aged and elderly people?

First, many elderly patients will experience arteriosclerosis, narrowing of the lumen of blood vessels, and blockage of the optic nerve and blood vessels, so it will cause vision loss. Second, the blood vessels of elderly patients will become brittle and thin, and fundus bleeding will occur, which must be carried out in time**. Thirdly, the abnormal increase in intraocular pressure in elderly patients is also an important cause of vision loss.

Appropriate supplementation of Jianshijia lutein can improve the symptoms of visual fatigue, alleviate the problem of vision loss, and help supplement lutein nutrition and vitamin A

As we age, our organs are slowly declining, and many middle-aged people often play mobile phones to cause vision loss.

With the increase of age, it is inevitable that the aging and degeneration of the function of the eye organs will occur, and it may also be caused by physical problems.

1.In order to earn more money and give their children and relatives a better living environment, they have been seizing the time to work, the amount of working hours is relatively large, and the load of the eye is large, resulting in excessive tension of the optic nerve, resulting in a decline in vision.

2.The underdevelopment of the physical health system, after all, when people reach middle age, their physical condition is getting worse and worse, and various functions of the body are declining, and the more obvious characteristics of this manifestation in the body are hearing, vision, smell, etc., so at this stage, it is normal to have problems with vision.

3.It has a certain relationship with diet, now people's lives are getting better and better, eating is more and more tasteful, for food is about color, flavor and flavor, and this means that the content of food additives and other chemical agents is too much, because the human body can not completely absorb or discharge these things, the human body has caused harm in the subtle, which is also an important reason for vision loss.

Give your eyes a break. When the elderly pay attention to something or concentrate on reading the newspaper, they often stare intently and forget to blink, which makes the eyes too tired and not conducive to the smooth flow of the eyes and blood circulation. Therefore, while looking at objects, you should also blink or shift your gaze to give your eyes a temporary rest.

Green objects, some green objects, including green plants, flowers, trees, green buildings, etc., are often seen. These green objects are good for improving the eyes, refreshing and protecting eyesight.

Develop the right reading habits. Do not read while lying down or when the boat is moving. These bad habits can damage your eyes and lead to vision loss.

Wear glasses correctly. If older people wear glasses, be sure to see a specialist for optometry before putting them on. Regularly eat foods that are good for the eyes, such as pork liver, lamb liver, chicken liver, milk, aquatic products, soybeans, black fungus, sunflower seeds, etc.

There are also foods that contain trace amounts of zinc, such as peanuts, wheat, potatoes, eggs, meat, and other foods. If you are deficient in vitamin A, night blindness and dry eyes may occur. Therefore, you should supplement with some foods that contain vitamin A, such as carrots, cod liver oil, egg yolks, etc.

Vision loss in older adults is the result of a combination of factors. Slow loss of vision is normal. However, if there is a sudden increase or decrease in visual acuity, it should be taken seriously and should be checked and ** in time to avoid missing the best ** opportunity.

Nutritionists suggest that middle-aged and elderly people with poor vision should take some health products that are beneficial to the eyes, which can effectively slow down the decline of vision in middle-aged and elderly people. The biggest feature of the eye care formula is that it contains a very comprehensive range of nutrients, such as vitamin A, DHA, carotene, blueberry powder and other substances that are good for the eyes; Blueberries can effectively inhibit enzymes that damage eye cells, scavenge free radicals, promote blood circulation in the eyes, and improve various eye problems, such as vision loss and dryness. These nutrients can be a good way to alleviate the phenomenon of vision loss in middle-aged and elderly people.

As we age, vision loss is inevitable, so you can eat more foods that are good for your eyes, such as black beans, do more eye exercises, look at your phone less, and get enough sleep.

Don't often look at electronic products, be sure to pay attention to living habits, do more eye exercises, prevent eye fatigue, usually give your eyes a massage, look into the distance, you can also see green plants.

In life, you should stay away from some smartphones, you should be able to do eye exercises often, you should also buy some eye drops to get a good avoidance, you should not overuse your eyes, and you should not play with your phone late at night.

Equip the elderly with a pair of reading glasses, let the elderly go out often, and eat more vegetables that are good for the eyes, so that the vision loss can be alleviated.

It is believed that this eye disease is a frequent occurrence in the lives of all middle-aged and elderly people. What are the main causes of vision loss?

1. Lesions.

Some middle-aged and elderly people cannot see clearly, and their vision deteriorates rapidly due to fundus lesions, glaucoma, cataracts, etc.

Or people with too high blood sugar do not pay attention in their daily life, and their blood sugar continues to rise, which is easy to cause lesions in other organs and has a great impact on the eyes.

2. Decline of organ function.

Vision loss in middle-aged and elderly people is caused by organ function decline to a certain extent and is unavoidable. However, the rate of vision deterioration varies among middle-aged and elderly people. This has a strong relationship with the habit of using the eyes on a daily basis.

Improper use of the eyes can lead to rapid aging and degeneration of the eye organs, leading to various eye diseases.

3. Don't pay attention to eye protection.

In real life, many middle-aged and elderly people are very frugal in life. They like to turn off the lights, watch TV and look at their phones at night, just to save a few kilowatts of electricity.

In a dark environment, whether watching TV or playing with a mobile phone, the damage to the eyes is huge. It is this act of not paying attention when using the eyes that also causes certain damage to the eyes, and the vision continues to decline.

Lutein and zeaxanthin in corn are very good substances with strong antioxidant capacity, and after light is inhaled into the eyeball, it can be well digested by these two substances, so that harmful light can cause damage to the bottom of the eye muscles, further ensuring eye health.

3. Eat more spinach.

The causes of myopia are complex, and there are many influencing factors, and the main factors are roughly divided into genetic factors, environmental factors and nutritional factors.

1.Genetic factors: According to a large number of survey data, the consensus conclusion is that high myopia is related to heredity, and there is a large difference between moderate myopia and less than moderate myopia.

The genetic type of high myopia is concluded by most survey data to be autosomal recessive. As a result, parents and offspring may not develop myopia at the same time. Heredity is often influenced by the objective environment, that is, the conditions of life, which makes it mutate, which increases the complexity of heredity.

2.Environmental factors: environmental factors are mainly close operation and poor working environment, which is the oldest theory, although there are still some controversies, but from a large number of domestic and foreign relevant research reports, it has been recognized that heredity and environment are the main reasons for the formation of myopia, and pointed out that environmental conditions are the objective factors that determine the formation of myopia.

1) Adjustment theory: The vast majority of myopia appears in adolescence, because the adjustment power of adolescent eyes is particularly strong, and they have a high degree of adaptability to work and study at close range, so they are not easy to get tired when they see close. However, if the ciliary muscle is over-tensed for a long time, the ciliary muscle will be fatigued or even spasm and accommodative myopia will appear, and if it is not eliminated in time, it can become irreversible true myopia.

or by other means affecting the elongation of the eyeball axis.

2) Divergence theory: When using the adjustment of close work, it is also necessary to strengthen the divergence function of both eyes turning inward at the same time, which can lead to the pressure of the eye muscle on the eyeball, which can cause the extension of the eye axis.

3) Environmental adaptation theory: In early childhood, the eyeballs are small, most of them are farsighted, and with the increase of age, the eyeballs increase to the state of emmetropia. Reading too much near up during this developmental process makes the eye myopic in order to adapt to this need for accommodation.

This theory has been opposed by many people, but it is a consensus that it is very malleable during the developmental period and has an important impact on the development of myopia.

Other theories are not introduced, but it is worth mentioning that external factors such as lighting, reading posture, contrast, small and blurred characters, too close proximity, and long reading time can all affect the role of these factors.

3.Nutritional constitution theory: From some data analysis, the deficiency of trace elements such as cadmium, strontium and zinc and the weakness of physical constitution can also affect the occurrence of myopia, but there are different ways through which these factors affect myopia.

In short, it can be seen from the above that myopia can be caused by many factors, both external factors and internal physical factors, rather than a single factor.

Resources. The view is roughly divided into three degrees. In terms of clinical symptoms, the disease course is less than two years, the degree is less than 200 degrees, the visual acuity is above, and most of them are pseudomyopia; The course of the disease is more than four years, the degree is more than 400 degrees, and the visual acuity is below, and most of them are true myopia; Half-truths and half-false myopia in between.

From the analysis of the age of netizens, vision protection is not good and will continue to worsen. Glasses or laser surgery may be done and eye hygiene should be observed.

The most important reason for the decline of vision in middle-aged people is due to the decline of ciliary muscle function, resulting in the decline of vision in the near eye, commonly known as presbyopia, the decline of vision in middle-aged people, according to the different clinical symptoms of the manifestation of many reasons, refractive error and age astigmatism in both eyes will lead to a significant decrease in distance vision, as well as a significant decline in visual quality, in addition to some fundus diseases, such as macular disease, macular degeneration, macular edema, macular hemorrhage, etc. Changes in visual quality such as visual distortion, in addition to some diabetes and hypertension-related fundus lesions will cause fundus retinal diseases, resulting in varying degrees of vision decline, and some reasons are due to the formation of visual fatigue after middle-aged people use their eyes excessively, resulting in blurred vision, dry eyes, astringent eyes, vision loss and other clinical symptoms, which need to be given corresponding treatment and treatment.
