What does my prescription mean? - 1

I have just got back from the opticians and I was diagnosed with short-sightedness. I opted to choose contact lenses and I am having a trial next week.

However, of course I also had to choose a frame and I am just wondering what my prescription means. I really should of asked my optician but I was kind of nervous.

It says:
Sph
Distance Right and Left: - 2.25

What does those numbers mean, how short sighted am I ?.
