Can lookin accidently into an extreme high voltade lightbulb at night lead to a floater in eye the nextday? i feel this happend to me

Probably not, but...: A floater is a physical particle floating within the vitreous jelly of the eye, and usually are fibrous (from the optic nerve), hemorrhage, or inflammatory cells. What you might have is a retinal injury from viewing the bright light, creating a persistent after image. If the "floater" perfectly follows the line of sight without any lag or movement then it is probably retinal, and should be checked.

Light burn?: It is unlikely that the light caused the floater. It is possible to get a retinal burn by looking at the light for several seconds at high intensity. Have the eye checked by a retinal specialist. There are several tests that can be done to analyze this and also assess whether the floater is new or an artifact from the light burn. Get a dilated exam.
