Are you sure the corrective lenses are the correct prescription for you? The first pair of prism glasses that I received (after extensive testing and evaluation by a very good Optometrist) were not right. I had another complete evaluation by the same Optometrist, and she made adjustments to the lenses. Second pair of prism glasses work great! I'm now waiting for third paid of glasses to be finished. These will just have correction for reading and up close. What is your worsening at nighttime? I assume you have dry eyes. What do you use for that, because it could be affecting your nighttime problems. I'm currently at the Balance Center and hope that helps.
