Is it normal to sometimes get temporary blindness after standing up?
Whenever I lay down for a long time and then suddenly stand up I get this blindness that last for about 10 or 15 seconds, I really want to know if this is common in most people because my parents think I may be going blind. I've had this for about a year now and it doesn't really bother me that much, the most harm it's done is hitting my shoulder into the wall.
