What is the difference between + and - powers on my prescription?

Plus Powers & Minus Powers

Your contact lens precription contains a parameter called power (or sphere). This is the vision correction applied by the contact lens. If you are far-sighted, this number will be positive, eg +1.5,. if you are near-sighted this number will be negative -, eg -2.5.

Actually, I believe far-sighted folks would have a positive number for correction.
My contact prescription is -6.5 and I am [quite] near-sighted B^)
