How does light pass through the dust into our eyes?

How does light pass through the dust into our eyes? In the environment we live in, there are many micro-things, which have always accompanied us and us humans to grow together, although some of them are alive and some are inanimate. But it has also brought about many important developments in our human life.

For example, beneficial bacteria are now used in the research and development of various antibiotics by humans, among which penicillin is the most widely spread. Dust is not visible in natural light, so there are several reasons why it can be seen with a flashlight.

First, the human eye cannot catch this dust.

First of all, the first point is that the human eye cannot catch the dust, the dust is too small, and the average volume of them is basically about 0.00 millimeters. It is precisely because of this that human beings cannot see these things, and human beings will discover their existence with the help of microscopes and various scientific instruments. After all, it is still relatively difficult for a human eye to make a discovery of these things.

Second, dust, they can reflect the light of the flashlight.

Actually, we also learned that dust, although it is said that it is very small, but it is a solid that actually exists. Because of this, when the dust is irradiated, they will reflect the light of the flashlight, and if it is in a dark environment or a poorly lit environment, they can reflect the light in it for humans to see. Especially in the summer, people will go to dry the quilt, and when they dry the quilt, they will pat the quilt, and there will be a lot of dust on it, which is seen by humans through the sun.

3. A question of human perspective.

The last point is that there are some reasons why dust cannot be seen, and it is because of the perspective of the human eye, if the perspective is selected, then the dust can be seen in the air. The perspective determines whether many things are visible to humans, and so does dust.

People who rush into their eyes like dust will subconsciously rub their eyes with their hands. In fact, this method cannot be used because they will have a lot of bacteria on their handsWe can wipe our eyes with a skirt, sometimes, it doesn't matter if we can't get rid of the dust, it doesn't matter if we don't wipe them all the time, if we wipe them for a long time, it will be very uncomfortable, when sleeping, he will constantly secrete fluids, the eyeballs will get wet, and the other will expel some dirt from the eyeballs.
