I've fixed glare that bad, and I can tell it's going to take a lot of time. Most of the work has to be done with the clone stamp. For the glare on camera-left, you can copy the other eye, flip it horizontally, place it on the left, and blend it in with a layer mask. But first you have to fix the camera-right eye.
Any possibility of re-shooting? On the technical points, this is a pretty bad picture: Camera angle looking down on subject, glare on glasses, shadow behind boy, subject off center facing out of the frame. Direct flash is just about the least flattering light you could use for this.
