What causes the floating irregular shadows that appear when blinking?

Vitreous opacity is mainly due to vitreous degeneration, degeneration, and vitreous opacity and floating caused by vitreous hemorrhage and exudation and peripheral inflammatory migration. In the presence of light, the retina forms a black shadow, causing the visual shadow to float. When you move your eyeball, it also rotates with it, which feels especially noticeable in bright light.

Physiological vitreous opacity does not need to be done, there is no perfect method of vitreous opacity in medicine at this stage, and a small amount of turbidity will bring visual trouble, but it will not bring harm.

If the black shade suddenly increases with the sensation of flashes, it should be noted,**Medications include, amiiodotide eye solution or antoiodine injection, which can promote blood circulation in the vitreous and help absorb turbidity, can be properly fed, such as animal liver, longan, lychee, carrot wolfberry, etc. are all good choices, usually you can do eye exercises, massaging eye acupoints is also the principle of promoting blood circulation and metabolism, and you should pay attention to the time, don't be too tired, and don't stay up late or overuse your eyes,** The principle is to actively control the primary disease, such as inflammation.

With laser or drug ** fundus hemorrhage disease, severe turbidity, long course of disease, fibroproliferative transformation can be vitrectomy, if the disease is mild, it needs to be distinguished from physiological floaters, physiological floaters are caused by embryonic residual cells or blood cells in the vitreous body when passing through the retinal blood vessels, projection on the visual cell layer, has no effect on vision, because the residual cells are very small, so it is not easy to find ophthalmoscope opacity, this is not an eye disease.

Sometimes there are some complications in vitrectomy. Therefore, complications from surgery should be prevented. If it happens, the vitreous may first need to be incised, and their common complications are as follows, such as corneal edema, cataract, vitreous incarceration, vitreous hemorrhage, glaucoma, retinal tear or retinal detachment, etc., which are very serious.

It is because there are cloudy substances in the vitreous body, and the shadows of the cloudy substances are cast into the eyes through the light, so you can see their shadows floating in front of your eyes.

Vitreous opacity, usually caused by lack of sleep or improper use of the eyes.

The floating and irregular shadows that appear when blinking are a kind of image caused by the sun's rays being refracted into the retina of our eyes.

If you've been staring at the glowing sky for a long time, or if you've stumbled upon the sun, you'll see a colored spot in front of you. With a blink of an eye, the spot becomes clearer, and the color keeps changing. Why do I have this kind of pigmentation?

What's the use of studying it? Let's do a little experiment, and this experiment is not to ask you to look at the sun, which is dangerous, and strong sunlight can damage the retina in your eyeball.

Gaze at a red object illuminated by the sunlight for a minute or two, then suddenly raise your head and turn your eyes to the white ceiling. At this time, you will see a floating blue-green, its outline is the same as that of a red object, and it is very brightly colored. This color can exist continuously for a few seconds; If it's gone, if you blink your eyes, it will reappear.

This means that every time you look at a color, all three color vision cells work together. Modern physiological anatomy has found that the tiny retina is a huge tissue system with a complex and delicate structure, and the retina is a thin film with a thickness of only millimeters attached to the inner surface of the eyeball, but it contains hundreds of millions of optic nerve cells, arranged in three layers.

The first layer of cells is used to sense light, and it can convert the light that is imaged through the lens of the eye into an electrical signal, which is different depending on the brightness and color of the imaging light.

The second layer of cells is used to receive and analyze the electrical signals they receive, and after they are analyzed, the signals are transmitted to the brain through the third layer.

Studies have found that photoreceptor cells on the retina are divided into two categories: cylindrical cells and conus cells, and the rod-shaped cylindrical cells can only sense light, but are not involved in color vision. They work when the light is low and are more sensitive to light.

Sometimes it does.

Because that's when you're at your most tired.

Actually, this is a normal phenomenon that everyone has.

Actually, it's a kind of plankton.

Actually, this is a normal phenomenon, and everyone will actually have a plankton.

It has a lot to do with the anatomy of the eye.

It's probably just a feeling in the heart.

I don't know if I've ever been like this.

Because that's when you're at your most tired, I don't know what happens.

I haven't been there, I don't know what's going on.
