I switch between glasses and contacts on a regular basis, depending on the occasion and the circumstances. With glasses, there's always the issue of keeping them clean. Is there anything more annoying than a smudge or a speck in the middle of your field of vision? I decided to seek out some advice so I set up a meeting with an expert on glasses to get some advice. Phil Coker at LaHaye Total Eye Care was a medic in the military and has been a vision specialist for his entire career. Phil knows all the tricks! He shares some great tips in this video.
