Anonymous users2024-02-07Why are the eyes different from those of the West? In general, there are four major human races in the world: yellow, white, black, and brown.
Most of the yellow people live in the East, so the yellow people are also called Orientals, they have black eyes, and the white people are just the opposite, they are called Westerners, they have blue eyes, why do people of different races, their eye colors will be different? The eyeball is composed of the cornea, iris and pupil, etc., the cornea is colorless and transparent, and the pupil does not change color, so the color of the eyeball depends on the color of the sub-iris. Let's start by looking at the structure of the iris of the eyeball.
The iris of the human eye is made up of five layers of tissue. They are the stromal layer, the anterior bounding membrane, the stromal layer, the posterior bounding membrane, and the posterior epithelial layer. Among them, the stromal layer, anterior bounding membrane, and posterior epithelial layer contain many pigment cells, and the amount of pigment they contain determines the color of the iris.
The relationship is that the more pigment a cell contains, the darker the color of the iris and the darker the color of the eyeballs, and conversely, the lighter the color. It is important that the pigment content of the cells is consistent with the color of the cell, and it is also related to ethnicity and genetics. People of color, such as Asians and Africans, have a lot of pigment in their iris, so their eyes look black, while white people have less pigment in their iris and their eyes are blue or gray.
Your eyeballs must be caused by the low pigment content in the iris, in fact, don't worry, many mixed-race children are like this. In addition, your condition may be hepatobiliary dampness or jaundice, or it may be a fatty membrane. It is recommended to go to a regular hospital for examination and diagnosis.

Anonymous users2024-02-05It may be that there is a lot of wind and sand in your usual living environment, and your eyes are larger or your eyelashes are shorter, so there is more chance of sand and dust blowing into your eyes; At the same time, you spend a lot of time in front of the computer every day, which causes you to rub your eyes a lot. We know that there is a membrane on the outermost part of the eyeball, followed by abundant capillaries in the eyeball tissue below, and in the case of frequent pressure and rubbing of the eyeball, the capillaries will have a small amount of bleeding, and over time, more and more trace bleeding causes it to be unable to be completely absorbed in time and accumulate in the ocular surface tissue. The outward sign is that the eye appears to be irregularly yellow (or pale orange or light brown) in a local position, and the eye does not necessarily feel uncomfortable.
It is recommended that you wear a pair of flat glasses when you go out on a windy and sandy day, rest your eyes for 10-20 minutes after operating in front of the computer for 1-2 hours (you can look at the distance and green plants), pay attention to eye maintenance, and use eye protection solution. Pay attention to nutrition, eat more vegetables, and you can also eat some vitamin health products. Try not to rub your eyes with your hands, and use other methods to remove unfeeling (such as asking someone to blow or use a clean handkerchief, gauze to gently cover your eyes so that your eyes can shed some tears to bring out the dust, or close your eyes to rest for a while).
Because the eyes are actually very delicate. May you be happy and healthy! x

Let's understand the causes first There are many reasons for tooth staining and yellowing, which can be roughly divided into two aspects, namely endogenous and exogenous. Exogenous staining is due to the presence of a variety of bacteria on the surface of the teeth, which secrete many sticky substances, tea scales, cigarette stains and certain minerals in drinking water in the daily diet adsorb on these sticky substances, and gradually make the teeth yellow or black. Endogenous staining is formed during tooth development, if tetracycline is deposited in the dentin, it will make the tooth yellow, brown or dark gray, called tetracycline tooth; If there is too much fluoride in the drinking water, it can also lead to dental fluorosis, which can be a white-chalk-colored, tan-colored patch, and can also darken the tooth if the necrosis of the tooth is combined with bacterial breakdown products. >>>More
