Just relax...Ive had numerous things just like this and its weird cuz ive been a healthy kid ever since I turned 16 which is when I started to notice some eye problems...Ive been to about 5 different eye specialists, neuro, neuropthamoligst, u name it ive been tehre...They foudn nothing wrong...I just was paying to much attentnion about what my eye was really seeing...I can see my blood vessels pass through my eyes which looks like, some have described, "shooting stars" but everythings alright....I can also see my heart beat in my eye if I focus on it...All this stuff goes away if u stop focusing on it...It will still be there but ur brain wont care anymore!
