Onion contains a volatile substance which can irritate your eyes, having tears is a protective reaction to this substance. It has no harm to your eyes, but has a certain function of detoxifying and cleaning. I can recommend you some suggestions to prevent crying: first, before cutting onions, you can put knife in cold water for a while, and then cut the onion. Second, cut the onion into halves, put them in cold water for a while, and then cut it to small pieces. Third, put the onion into warm water for three minutes, and then cut.
Some people think cutting onions is good for eyes because it can cause your eyes tearing. The tear can help get the dirt or dust out of your eyes, thus it can help cleanse the eyes. But it has nothing to do with the eyesight. However, there are some people who think cutting onions is not good for eyes because it can cause irritation, swelling or redness in the eyes. So people should cut onions under water.
To some extent, yes. Because Onions contain a volatile substance. When you cut Onions, they will stimulate your eyes, and your eyes protect themselves instinctively and begin to cry. Therefore, cutting Onions is not harmful for body but to the eyes has certain good effect. But the taste of onion is really stimulating, you can avoid by this: putting the chopper in cold water before cutting onions for a while, or putting the onion into cold water for few minutes after cutting Onions in half.

I don't think it will good to your eyes because cut onions make my eyes feel painful and tearing. I know that tear is the natural water to benefit our eyes. If the smell of onions make you tearing, it means your eyes are healthy because it is react properly. But cutting onions itself is not a healthy way.
