I've got the exact same problem mate, and there is not a whole ton you can do to control it. It comes down to many factors and a lot of it simply has to do with your genetics - some people tend to sweat more than others and/or have a higher body temperature, and the areas that people sweat from tend of vary from person to person.
A simple preventative measure you can use to avoid getting sweat in your eyes, is to wear a headband or a bandana around your head while you exercise and play sports. There is lots of light head gear that is designed to absorb sweat from your forehead and soak it up so that it doesn't get in your eyes.

abnormal, you could always go see a doctor about it. Some people have problems with extreme perspiration, and there are all types of solutions to getting it under control - anything from creams or special deoderants to surgeries that target the sweat glands.
If you are somebody who simply has a higher body temperature than most people (like myself), here are some tips you could try that might help you control the amount that you perspire:
