The wind and sand in the north is strong, and the clinic often comes into contact with some patients who have foreign bodies in their eyes, often because of improper treatment before consultation makes the condition worse, so their own pre-treatment is very important. The first thing you should not do is rub your eyes. Many people think that if you rub your eyes, they will come out, but in fact, in many cases, rubbing your eyes is a way to make the foreign body stick to your eyes. In this case, the first thing you should do is flush your eyes, with saline if you have the conditions, or with tap water if you don’t. Flip the upper and lower eyelids and flush them, while turning your eyeballs, most of them can be flushed out. Some patients always think that the problem is not big and wait to see if the foreign body will fall out by itself, but the process of waiting is often the process of foreign body causing inflammation of the eye or even the cornea or infiltration of surrounding tissues, and then the damage to the eye will increase when dealing with it, so don’t turn a small problem into a big problem.
