Of course, it is.
Don't rub your eyes with your hands, especially your fingertips. You use your hands every day for many things, your fingers must be full of dirty things like germs and dust. The fingertips contained a lot of germs which may be taken into your eyes . As a result, you may get an infection or inflammation in your cornea. That's how rubbing your eyes cause keratoconus.
Rubbing eyes can cause keratoconus. A scientific research has showed that rubbing eyes as a habit is commonly shared among keratoconus patients. The corneas of the people who are suffering from keratoconus have been weakened by inflammation, and become very thin. The external forces from eye rubbing will pose the danger of further weakening and even protrude the corneas. If you have this habit, quit it now. In addition, keratoconus can also be caused by overexposure to UV, wearing unfitted contact lenses for too long and chronic eye irritation. So you should pay attention to these factors as well.
