A typical contact lens prescription contains many numbers and abbreviations. One of the most important details in a lens prescription is "PWR," which stands for "power." This refers to the refractive power that your eye will need to be able to see with 20/20 vision. Simply put, "PWR" refers to the strength of your contact lens.
