No, these two types of prescriptions differ quite substantially. Firstly, your glasses sit on your nose at some distance from your eyeballs, which means that their spherical powers responsible for your crisp vision will be different. Secondly, in your contact lens prescription you will find eye parameters, which don't feature in your spectacle prescription, such as B.C. or DIA. Sometimes your eye care practitioner will also put a brand name on your lens prescription, to make it easier for you to choose the right product.
