What are the symptoms of old eye flashes and how are they caused

Astigmatism is a refractive abnormality of the eye that is related to the curvature of the cornea. Some people have a curved cornea in one angle and flatter in others. The cause of astigmatism is that the refraction rate of each meridian of the cornea is inconsistent due to the uneven thickness of the cornea or the uneven curvature of the cornea, so that the light rays passing through these meridians cannot be concentrated at the same focal point, and the light rays cannot be accurately focused on the retina to form a clear image, which is called astigmatism.

Astigmatism simply means that the eye is not well developed, and there is a phenomenon of unevenness. And now there are more and more children with astigmatism, and children's astigmatism is directly related to the serious lack of vision nutrients, as well as bad eye habits.

Children with astigmatism first need to supplement vision nutrients in time, it is recommended to take Lejing vision nutrients, twice a day, one pack each time, take it with warm water, insist on taking it for a period of time, and astigmatism will gradually recover.

The other is to develop good eye habits.

1. Regular eye examination 1 2 times a year. Instruct young children to practice good hygiene and not to contact their eyes with their hands or chemicals. When reading, there should be plenty of light, preferably from the left rear; Correct posture and a distance between 30 cm and 40 cm.

2. When choosing reading materials, the font should be clear and not too small.

3. Watching TV must be 5 7 times the diagonal of the TV picture. Read a book for no more than one hour in a row. If you need glasses, you should be examined by a doctor and then dispensed with glasses.

I don't know what you're flashing, it's better to go to the hospital and see, there's a floater called floaters that you're not.

What's the matter with the flashing eyes.

The most common factor of flash in ophthalmology is caused by vitreous traction of the retina, which is one of the symptoms of retrovitreous detachment. Generally not required**. However, it is necessary to pay attention to resting the eyes, once similar symptoms appear several times, or local visual field defects suddenly appear, you should go to a hospital in time to check the fundus to prevent retinal detachment.

Eye flash is a disease that is caused by a disease of the eye. Prompt recommendation**.

The cause of this condition: Eye disease.

It is because the retina is behind and cannot see clearly, and the main cause is that the eye is inactive for a long time, so that there are some defects in the visual field, resulting in flashes of light. Of course, the most common cause of ophthalmology is vitreous traction of the retina, which is one of the manifestations of posterior vitreous detachment.

Once this kind of situation often occurs, it is first recommended to go to the hospital in time to check the fundus to prevent retinal detachment.

The second is to insist on doing eye exercises, pay attention to the daily eye habits and eye hygiene.

Finally, it is combined with oral Le Jing Blueberry Lutein Ester Tablets, which is taken for a period of time, which is very helpful for the daily maintenance of the eyes and can also prevent the occurrence of fundus diseases.

Astigmatism refers to the disorderly vision, which is caused by the improper curvature of the cornea, and the problem of astigmatism often appears in children and adolescents, and the factors that cause astigmatism are as follows:

1. The change of astigmatism during myopia, the eyes look inward and downward, and the eyeball rotates at the same time, which is the change of the astigmatism axis of the eye, so the appropriate lenses can be selected according to the different ages, focus depth and relative adjustment force of the patient.

2. The symptoms of visual fatigue are usually related to age and the nature of the work, the older the person, the person who writes at the desk, will cause mild to moderate astigmatism, if it is lower than the normal value, it needs to be corrected.

3. The impact of spectacle lenses is due to the uneven size effect of the glasses around the moving lens surface, and sometimes the size of the frame may also affect the peripheral optics and cause astigmatism.

A flash of light is when the surrounding environment does not change, but the patient sees lightning-like light, and it is continuous.

The concept is that the retina is detached and the photoreceptor cells cause light.

What's the deal with a sparkle in front of your eyes?

The reasons for the sparkle in front of my eyes are:

1. The most likely cause is posterior vitreous detachment. Vitreous is a transparent, colorless, gelatinous substance with certain viscosity and elasticity, such as egg white, located in the intraocular cavity, adjacent to the retina, when the vitreous and the retina are separated, it forms a posterior vitreous detachment, and the retina is stretched in the process of detachment, that is, the vitreous body causes a kind of pulling force to the retina, which will produce a sense of flash, often accompanied by a small black shadow fluttering in front of the eyes. There is a high incidence of elderly and high myopia and is not required**.

2. Retinal photoreceptors and retinal outer layer lesions: white spot syndrome, etc.

3. Tumors: the most common are choroidal melanoma and metastatic cancer.

4. Central neuropathy: cerebral ischemia, migraine, intracranial mass, etc.
