What causes a retinal tear or detachment?

A retinal detachment can be caused when the vitreous in the eye pulls on the retina, tearing it or lifting part of it away from the back wall of the eye.

And ? What causes it?? No body can answer that question. How and why does the eye “pull so much “ ???
Computer ?? Welding?? Exercise?? What??

Did you say retinal detachment starts with old age, I hear little about trauma to the eye, as happened to me.
I went for an eye test nothing at all serious wrong with my eye, but within a day I had flashes and cobwebs in my eyes., and as in one of the comments said I am practically blind in one eye.

I read the success rate of lasering a small retinal tear is about 90% if you catch it in time. However, i wonder if those people ever get normal vision back? When they say "success rate" does that mean those people get most or all of their normal vision back? Or is that blurriness they got from the tear permanent even after being treated with laser and tacked done?
