Well, I have to say that some small, foreign particles, like sawdust can be annoying to your yes. And in some cases, it can also irritate the eyes. You should know that even if the sawdust is very small and not visible, if they stay in your eyes, they can still lead to a lot of eye discomfort. Of course, in most cases, tears will wash sawdust out of the eye. So you should not worry about it. But on the other hand, if it is serious, you should take some measures to get them out of your eyes. First, you should wash your hands carefully with soap and water. And then you can look in the mirror and try to locate the sawdust particle in your eye. Also, blinking several times in an attempt to remove the sawdust with little effort is also essential. In this way, you can allow your eyes to tear up, so that the tears may wash the sawdust out. Remember that you should not rub your eyes, or it can hurt your eyes. Generally speaking, you can gently dab the tears with a tissue.
