SPH means sphere and is also sometimes given as PWR or power. Basically it means how strong a lens it is. 0.00 means it doesn't have a power and is not a correcting lens, it's just cosmetic.
I think the second number is just an expiry date and the third is a serial number, so those aren't part of the prescription.
Did you get an actual prescription from the eye doctor, or do you not need any correcting contacts or glasses at all?
