Brief Answer:
Due to pull of the vitreous on the retina

Detailed Answer:
Thanks for asking on HealthcareMagic.

I have gone carefully through your query. There is a gel like substance called vitreous humor inside the globe of eye (behind the lens). The inside of the eye balls are lined by the photosensitive layer called retina. The vitreous humor is attached to the retina by thin strands. Due to some reason if the vitreous strands face a pull, the retina gets stimulated and this is perceived as a flash in the periphery of the eye (since the attachments are in the periphery).

You need to get an ophthalmological check up done. It would indicate if there is any pathology involved with the retina.

Let me know if I could help further.

Regards
