1. The most common causes of photopsia is vitreous detachment due to posterior vitreous detachment and it is much more common in the dark or semi-dark.
2. It would be very unlikely this this is a floater.
3. Since this is a new problem I suggest you consult an ophthalmologist.
4. On the outside chance that you have new glasses or contacts sometimes this can be reflections off the back surface of glasses or edge of contacts.
Thanks for your response , a further quick question
Are true flashing lights very bright and obvious to the patient? Can they fix there gaze on the ?
Just this evening I thought I was seeing some flashes at the top of my vision in the dark but can't really tell if I am or if maybe i just being overly aware.
I will visit an opthalmogist but would appreciate your expertise of patient experiences.
photospsia or flashing lights due to PVD and vitreous traction are extremely bright like a flashbulb going off in the eye or a bolt of lightening at midnight.
