Depending on how bad the glare is and where it is on the glasses, e.g. is it over the eyes or not, there are a few things you can try. Easiest is just the the Auto correction tool. If that doesn't work, you can try one of the following. Select the glare area with the brush tool and select colorize, then use the dropper tool to select an area in the glasses that does not have glare and use that color to replace the glare. Other method is to select the glare and use LCH or any of the Light tools to lower the luminosity of the glare. Those are methods that quickly come to mind.

Bob hit the most commonly used options. One added thought is to use "Protect Highlights" in the Quick Adjust menu.
These suggestions can all be used in combination. I find that the order is Protect Highlights, Colorize, then the Auto Retouch tool for difficult corrections (leave out steps you don't need). As Bob said, Auto Retouch by itself may be enough.
