Anyone else out there with vitreous detachment?

Question

How long will the light flashes last, I'm going insane!

Answer 1

until u have retinal tear or detachment. (the traction on the retina caused by attached vitrous stops,which causes the stimulation of retina causing flashes of light)
u must undergo a surgery to prevent tearing and detachment of the retina (vitrectomy) which leads to visual loss.
