Any Danger to Eyes Using LED Blue and Red Light Therapy?

I have purchased a blue and red light LED therapy machine for home use. I have beginning glaucoma and wonder if there is any danger in using this machine? I use the plastic eye googles that block the eyes completely and I keep my eyes closed. Are there any doctors out there that can answer my question? My doc didn't know what the machine is so no help from him. Thank you.
