Why can't i lift if history of retinal tear?

Retinal tear: If the retinal tear is recent, you should take it easy until your eye doctor confirms that the laser treatment was adequate. After that, there is no reason you should have to limit your activities (ie lifting).

Can get worse: Heavy lifting, bending, or straining can worsen a tear or create new ones in the eye shortly after a tear first forms. Listen to you eye doctor.
