The flight was planned for an on the hour departure.  The flight crew sent an acars requesting a 15 minute early push. The flight cannot arrive more than XX minutes early per management directive and the flight was making XY minutes early enroute. I meant to click on 'Standby' button in alert messenger; but apparently clicked the 'Early departure approved' button by mistake and flight pushed early; giving them an ETA at ZZZ nearly 1 hour early.  Did not catch the problem until I realized that the flight was showing out and off.Was clicking a little too quickly and mouse cursor apparently was just out of place.  Part of the problem was also that my management-dictated COVID-19 mask was causing my prescription glasses to fog; making it harder than usual to see the mouse on the computer screen.
Dispatcher reported erroneously giving permission for a flight to depart early.
