Competition goggles and ordinary goggles

In fact, the role of the mirror is not to prevent the mirror from being dropped while diving. Generally, in order to reduce the water resistance, mirrors are thin in shape, which is absolutely suitable for competition. In fact, there are several factors that prevent you from diving into the water. First, as my friend said above, it is the diving angle, or it should be the diving angle of your head. When you jump into the water, you should look down with your eyes, put your hands in front and your chin in your heart, so you shouldn't go into the water! Because your forehead bears most of the water resistance. On the contrary, if you look forward when you fall into the water, your diving momentum will be borne by the position of your goggles, so it is easier to enter the water. Another way to prevent goggles from entering the water is to wear goggles with two straps (in fact, most of them are tied). When wearing, the distance between the two belts is pulled apart, that is, one is high and the other is low (I mean the back of the head), which helps to balance the stress points of the goggles, so that even if there is water resistance, it will not enter the water. The third and easiest way is to tighten the goggles, but you may wear them twice more! Ha ha! Never wear goggles when swimming in public swimming pools on weekdays, because there is no rubber edge, and the protection around the eyes is definitely insufficient. If someone accidentally bumps into you, you will definitely die of pain! So be careful!
