Many people like to buy onions to cook and eat. But in the process of making onions, it is a very difficult problem to cut whole onions into the desired status. This is because when the onion is cut open, its tissue cells are destroyed and alliinase is released. This special enzyme evolved onions for the invasion of local pests. Alliinase reacts with onion's own amino acids to produce a gas with sulfur. When this gas comes into contact with the eyes, it will stimulate the nerve endings of the cornea of the human eye, so the human body through the nervous system instructs the lacrimal gland to secrete tears, flushing this irritating substance away. The emergence of this phenomenon is due to the body's own protective mechanism. Therefore, there have also been various ways to solve this problem on the Internet. One of them, as an accessory for eye protection, produced a protective goggles called "onion ring glasses". Use physical protection to protect your eyes when cutting onions. The shape of this goggles also follows the fashion trend, suitable for men and women of all ages. The material is also environmentally friendly.
