Flash of lights and visual focus problem

For the past 2 months I've been seeing these flashes of light in the corner of my both eyes occasionally once or twice a day or week (I don't wear any glasses). Last month (19/11/25) I got my eyes checked and the doctor said I've 6/6 vision and there's no retinal detachment in my dilation exam and gave me a few drop for my eyes to keep it wet/moist. The flashes have reduced in a significant manner but I've been facing trouble concentrating for a while like I can't see stripes etc for a while or I will get kind of dizzy. Or looking at my peripheral vision items kinda seems like popping ?¿. And yes I see them moving when I close my eyes in the corner of my eyes.I have a tendency to overthink i barely see any of it outdoors or when I'm with any company but it increases significantly when I'm alone in a room etc. so what should I do? P.s these flashes occur at night mostly after I am awake past midnight or in a dark environment. However, these flashes aren't as bright as they used to be.
