For glasses glare a couple of things: First, a circular polarizing filter can help. Second "key lights" don't have to just be your monitor. You can dark mode the monitor you have in line with camera and leave it at low brightness, then bring in the primary lighting from the side (another monitor, or a cheap/home-made soft box would work - a diffuse desk lamp may serve well, or a strong harsher light bounced off a white wall ). You can't stop light reflecting off your glasses, but you can make sure most of it doesn't bounce into your camera. Not if you go very directional on the light you may need something to fill from the other side so you don't get strong shadows. One source should be ok if you only give enough angle to loose the reflection.
