No: Vitreous separation ; traction on the retina causes retinal tears-causing vitreous floaters ; hazy vision. Untreated, these tears allow fluid to flow behind the retina amd it falls off the back of your eye-like wallpaper coming off a wall. This causes a veil in your side vision then painless central vision loss. Lifting or straining does not cause these problems. Hitting your head can.
