Poor vision, look at things as gray ... Don't care, check at 5 o'clock to be alert to cataracts at 5 o'clock

What early signs of patients need attention?

1. The visual object is hazy, fixed black shadow

Patients will feel that there is a layer of fog in front of the eyes. Seeing things is gray. In front of the eyes, there may be dots or shadows or shadows that are fixed in front of the eyes and have nothing to do with the rotation of the eyeball. The black spots or shadows of turbid flying mosquitoes are different, and the latter will move with the rotation of the eyeball.

Second, temporary myopia

Early cataracts expanded due to the absorption of water in the crystal body. Its thickness increased, and the refractive power was strengthened. At this time, the close vision improved. Instead, the person wearing a flower mirror was taken away from the old flower mirror. It

The number of myopia is deepened. People often mistakenly believe that they are "returning to the old age". In fact, this is an ominous sign.

Once the water in the crystal body is absorbed, the refractive state is restored again, the turbidity begins, and the vision decreases. Diabetes people have risen blood sugar, the water osmotic pressure in the eyes changes, and the crystal body expands, and similar refractive abnormalities will also occur.

Third, color sense abnormalities

Due to the hardening of the crystal body, the crystal nucleus absorbs short -wave light, which causes purple or blue and blue obstacles; or because the crystal absorbs moisture, irregular swelling occurs, and sometimes the colorful spots can appear in the light.

But to distinguish the colorful ring of glaucoma, the color rings shown by glaucoma are like the rainbow of the sky sunny after the rain.

Fourth, the dark environment is more clear

This is because some patients are in the center of the crystal turbidity. In a relatively bright environment, the pupils are narrowed, and the crystal of the central turbid in the center prevents the entering of the light.

Instead, the pupils are relatively large in a dim environment, and the light can enter the eyes through a relatively transparent peripheral crystal.

Fifth, see more clearly in the bright environment

This is because some patients are crystal turbid parts around. In a relatively bright environment, the pupils are reduced, and the light enters the relatively transparent crystal of the center.

On the contrary, the pupils are relatively large in a relatively dim environment. The surrounding parts exposed are turbid. The amount of light entering the eye does not increase, and the vision is poor.

The above is the early performance of cataracts. If you find that you have the above symptoms, please go to a regular medical institution for examination.
