There really is not a way to check the "accuracy" of the prescription of a soft contact lens. It's rare for the Rx to be off but mistakes do happen! Luckily these days lens manufacturers will gladly send a trial pair of contact lenses to your eye care professional at no charge. The trial pair is the EXACT same quality as the lenses you will eventually purchase, which allows you to both test out comfort and power before dishing out the big bucks for what seems like a lifetime supply

. Unfortunately, when one moves to bifocal contact lenses in either a multifocal design or through the monovision set up, there will always be compromises to make. The easy solution is to go back to wearing your progressives (multi-focal glasses). It sounds like you need to go back to your doctor for a follow up and have a few trial and error sessions with him! Good Luck!
