Yeah, it's so tempting to rub them, but you can do some real damage. On a basic level, you're transferring germs from your hands, which can cause infections like pink eye. You can also break the tiny blood vessels on the surface, making your eyes look bloodshot.

If you have allergies, rubbing is the worst. It releases more histamines, which is the very chemical that makes your eyes itch in the first place. You get trapped in an itch-rub cycle. The most serious risk is damaging your cornea. Over time, constant, hard rubbing can weaken it and cause it to bulge into a cone shape, a condition called keratoconus. This can permanently blur your vision. It’s best to use cool compresses or eye drops instead.

If we do not reduce friction, there are many problems for machines. The parts that are moving will rub together very hard. This will make so much heat. Sometimes, the machine gets too hot and can even stop working. This is very bad.

Also, the parts will get damaged. They will wear out very fast because of the rubbing. You will have to change the parts again and again. This costs more money.

The machine also becomes very slow. It needs more power, like more petrol or more electricity, to do the same job. So much energy is wasted just fighting the friction. So, it is not efficient. For a machine to work smooth and for long time, we must reduce friction.

It's a law thing in Japan, mate. They have a very old law. I think it is Article 175. This law says you cannot sell or show "obscene" things. Because of this, they must cover the genitals. That is why you always see the blur or mosaic on the screen. It is a bit strange, yeah? But all adult videos made in Japan must follow this rule. It is just how it is there.
