Welcome to JA and thanks for this question. Im sorry to hear about your symptoms. Actually flashing lights can indicate that there is damage to the underlying retina or even to the lens, usually when the intra ocular pressure is well controlled then you would not be experiencing the lights due to glaucoma at all. If the glaucoma is well controlled that is the pressure is normal. Now if glaucoma is ruled out as a cause then flashing lights in the periphery or photopsia, can be due to problems with the vitreous humor of the eye. This is the jelly like material which is present between the cornea and the retina, the inner and outer portions of the eye. This would be due to shrinkage of the vitreous humor or even due to hemorrhages in the region. Usually this would be diagnosed on the basis of a slit lamp examination.

ANother cause of this could be associated not with the eye but due to ocular migraines which can present even without headaches and just with eye symptoms like flashes of light, blkurring of vision etc. this would be diagnosed on a clinical examination and then would be treated with the help of medications to prevent the attacks.

Lastly, flashing lights in the vision can be evident after looking directly into bright lights but it should not last for a few moments and if you are experiencing this even without the bright lights then the above conditions should be evaluated for.
