The real reason is that, like sailors, they must constantly change their position between the dark deck and the bright sun. Wearing an eye mask on one eye can ensure that one eye can always adapt to the darkness. When you have to flirt under the deck, simply change the goggles to the dark side to get used to it. @ Objects in the air movement will be subject to resistance, the size of the resistance and the size of the object and the air in contact with the surface area. The smaller the ratio of the surface area of ​​the object to the size of the gravitational force, the more easily the resistance is balanced with the gravitational force. That is to say, the microscopic object can fall in the air at a very small speed, so
