It's not retinal detachment lol. You would notice that, like bear said you would see a classic "curtain drop" thing going on in one eye. It's an acute thing where you suffer a blow to the head or maybe some crazy intraocular shearing from high pressure vitreous and your visual field in the effected eye begins to disappear more or less top to bottom, things just slowly go black starting from the top of your vision.
I would still make an app to figure out what the flashers are but don't run in worried that you have retinal detachment if you still have full vision in both eyes with no history of trauma
I had a retinal detachment - Does not necessarily need to come from impact trauma. Smoking, diabetes, and genetics are all factors as well.
But yes you should see and ophthalmologist. Better safe than sorry dude.
