Glasses look at the light at night to see what is going on

Blurred vision may be caused by refractive error, cataract and fundus disease, etc., which need to be corresponding**.

1) The most common is refractive error, i.e., myopia, farsightedness, and astigmatism of the eye. Myopia is mostly due to blurred vision caused by excessive corneal flexion or elongated eye axis; Hyperopia is caused by too small curvature or shortening of the eye axis, etc., and the vision is blurred from afar; Astigmatism, on the other hand, is a symptom of imaging ghosting caused by inconsistent corneal curvature. It can be solved by glasses or surgery.

2) There is also a more common condition in middle-aged and elderly people, that is, cataract, which is medically called lens degeneration. Changes in refractive power due to changes in age or degeneration of the lens caused by excessive UV exposure can also lead to blurred eyes. Various drugs such as traditional Chinese medicine can only be slightly improved, and the essence does not change, and this problem can be solved through intraocular lens implantation, and even multifocal lenses can be selected to improve myopia.

3) Vitreous opacity, which also often occurs in middle-aged and elderly people, can be relieved by traditional Chinese medicine, etc., if the degree of opacity is severe, vitrectomy is required to fundamentally improve.

4) Fundus lesions, such as macular degeneration and retinal detachment, will also bring blurred vision or even more serious conditions, and it is necessary to go to the hospital for perfect examination and timely**.

Itchy eyes and blurred lights at night can be caused by a variety of reasons. Here are the possible reasons:

1.Dry eye: Dry eye is a common eye condition in which one of the main symptoms is itchy eyes.

Dry eyes cause insufficient or poor quality of tears on the surface of the eye, which can cause itching, burning, and dryness in the eyes. When looking at street lights at night, it can lead to blurred vision due to insufficient lubrication on the surface of the eye.

2.Allergic conjunctivitis: Allergic conjunctivitis is an allergic reaction to the eye, and common allergens include pollen, dust, pet dander, etc.

When the eyes come into contact with allergens, they can cause symptoms such as itching, redness, and watery eyes. When looking at the street lights at night, if the eyes are allergic, it may cause blurred vision.

3.Eye strain: Eye strain can occur when staring at an electronic screen for long periods of time or performing high-intensity visual work. When the eyes are strained, you may feel itchy eyes and blurred vision. These symptoms may be exacerbated when looking at the lights of a street lamp at night if your eyes are already tired.

4.Myopia or astigmatism: Myopia or astigmatism is a common vision problem that causes distant objects to blur. If you feel blurry when looking at the street lights at night, it may be due to myopia or astigmatism.

5.Eye diseases: Some eye diseases, such as keratitis, conjunctivitis, etc., may cause itchy eyes and blurred vision. If your symptoms persist or worsen, it is advisable to consult an ophthalmologist for further investigation and diagnosis.

To relieve the symptoms of itchy eyes and blurred vision, you can try the following:

1.Keep your eyes moist: Use artificial tears or eye drops to relieve symptoms caused by dry eyes.

2.Avoid being overly cautious about dispersing allergens: Try to avoid contact with substances that may cause allergies, such as pollen, dust, etc.

3.Rest your eyes: After a long period of visual work, give your eyes time to rest, away from the electronic screen, and close your eyes for a while.

5.Medical consultation: If symptoms persist or worsen, it is advisable to consult an ophthalmologist for further investigation and diagnosis to determine the specific cause of the symptoms and obtain the appropriate **.

Answer: It is the Tyndall effect, when the light passes through the particles, it will regret that this situation occurs, which is equivalent to the anti-blind first shot of dust, after all, the light intensity of the street lamp is limited, so the effect of the blue notice is also limited.

1.Crystals are mixed, the outside light is strong during the day, the pupils are narrowed, and the turbid crystals block the visual path and cannot see objects clearly; At night, the pupils are dilated and light enters the eyeball through the surrounding transparent lens, so the vision is improved.

2.There is a problem with the macula. During the day, the macula (**retina) plays a major role, and some objects can also be seen in the peripheral retina at night.

3.Caused by yin deficiency and fire. You can take the Chinese patent medicine Qi Ju Dihuang Pill appropriately**.

If there is no organic disease of the eye, it may be a liver and kidney yin deficiency according to traditional Chinese medicine, and you can generally eat some Qi Ju Dihuang pills. The above is a reflection of "the eyes can't see clearly during the day, especially blurry, and at night they can see more clearly."

Luminous flux.

Glare indicates that the lumens are large and the brightness is high.

What is emitted to the surface of the object to be seen by us is a large luminous flux, that is, the brightness obtained per unit area.

For example, two 6200k 600 lumens bulbs, one 35w and one 50w, their brightness is the same, but when they hit the surface of an object, the visual perception of our eyes is different.

For example, a 4500k and a 6200k light bulb are both 35w, and they are not the same brightness, and the visual effect on the surface of the object is also different for our eyes.

The light gradually increases in brightness from red, yellow, white, and purple, while the penetration gradually decreases.

1.It may be caused by long-term exertion or not paying attention to your usual diet. If there is a large amount of blood sugar in the human body, it is easy to lead to the appearance of diabetes, and it may also cause various types of diabetes complications, such as diabetic heart disease, diabetic eye disease, diabetic nephropathy and so on.

If you often eat some high-blood sugar foods, it is not only not conducive to diabetic retinopathy, but also directly affects the blurred vision of the eyes, and there is a problem of delay.

3.It may be an unhealthy lifestyle habit. Smoking and drinking alcohol can lead to eye diseases, affect the formation of diabetes, and eventually trigger abnormal reactions in the blood circulation, and may also lead to vision loss in the eyes.

If you want to control this disease, you should control it in time to reduce the damage caused by the dilation of blood vessels, and then avoid bleeding in the eye.

4.If people are often exposed to poor hygiene, it is easy to cause bacterial infections in the eyes, and it will also cause reactions such as severe redness and swelling of the eyes, and sometimes affect the vision of the eyes. In particular, some patients with high blood sugar are often accompanied by retinal lesions, and if they read books for a long time and overwork, they are easy to cause eye diseases.

Visual acuity is usually checked or corrected. Vision is generally normal in sunny places or during the day, but there is significant vision loss in dark rooms or at night, and the possibility of night blindness is highly suspected. There are many causes of night blindness, such as retinitis pigmentosa, advanced glaucoma, keranomalacia due to vitamin A deficiency, congenital fundus diseases, etc.

In addition, mild night blindness may occur in highly myopic eyes at night.

It may be caused by long-term exertion or not paying attention to your usual diet.

You can get an eye check-up!

If you don't look at your phone, you can go for an eye examination. Get an eye drop.

Insufficient blood supply due to overuse of the eyes;

or get up too violently and cause insufficient blood supply;

In short, the cause of blurred vision is caused by insufficient blood supply to the eye! , pay attention to eye time, pay attention to the rest in between, and minimize close contact with the computer, you should pay attention to this disease at ordinary times, otherwise you will suffer from it for a long time.

It is mainly caused by excessive eye use, resulting in eye fatigue 1. Insist on doing eye exercises every day to prevent myopia from deepening. 2. When looking at the computer, often blink actively, because people's eyes will not blink automatically in front of the computer screen, causing dry eyes. 3. Take a 10-minute break every time you use the computer or work at close range for 1 hour to relieve visual fatigue.

4. Rest more

You must turn on the small lights when watching TV at night, otherwise it will hurt your eyesight.

Turn off the lights before going to bed and stop looking at your phone and TV. Be sure to turn on the lights if you want to see it.

Don't watch TV without the lights on, and get enough sleep and rest.

Either turn on the light and look at it, or you don't look at it at all, or you will be blind sooner or later.
