Hi, this is what is mentioned on wikipedia which is NOT always correct :
'Some doctors recommend avoiding activities that increase pressure in the eye, including diving, skydiving, again with little supporting evidence. According to one medical website, retinal detachment does not happen as a result of straining your eyes, bending or, heavy lifting.[14] Therefore, heavy weightlifting would appear to be fine. However, two recent scientific articles [15][16] have noted cases of retinal detachment or maculopathy due to weightlifting (specifically with the Valsalva method), and a third documented an increase in blood pressure in the eye during weightlifting [17].'
The only exercises that i feel would increase the chance of getting a retinal detachment would be performing 1 rep max squats and deadlifts, which imo should only be done if you were training to be a powerlifter or for strongman competition.
You can lift your weights just don't stand on your head.
