Seeing black dot in vision, then changed to white dot? I started seeing this last week. Its a white dot(1-5 dots) then changed color to black dot..this worry me. Last 2011 i accidentally press my phone's camera near in my eye, after that i started seeing that dead pixel(white dot), nexy 5 years i started seeing it in my vision(noticeable at morning/outside/night. im worry this is retinal tear because it won't go away.(i have floaters already).

The transparent white dots->black dots appear sometimes in my vision and won't go away. A week before i started seeing lighting flashes before waking up.(almost 2 weeks). 

Also i have lazy left eye since birth. 

should i visit my eye doctor next month or asap? 

By the way i live in Toronto Canada.
