This prior week I experienced a retinal tear/separation in my right eye. I recognized what was happening, so I quickly sought doctor’s care and had laser surgery to repair the tear and “tack down” the retina. I am convinced there are multiple contributing factors including age (62), rather myopic vision (a stigmatism), perhaps trauma in the past from sports, …. And of-course countless rounds of recoil absorbed from shooting rifles and shotguns.
This experience has given me cause to ponder how much shooting may have contributed to my condition. More specifically, how it contributes. It occurs to me that there are at least two sources of recoil trauma to account for; the recoil energy transferred indirectly to the shooter’s head/eye via the recoil pad, and the energy transferred directly to the head/eye via the cheek weld on the stock comb. I am interested in investigating answers to the following questions;
1. What percentage of the total recoil energy is transferred to the shooter’s head via the butt pad and what percentage is via the stock comb ?
2. How much more it the transmitted energy for shooters using a heavy cheek weld, vs medium or no cheek pressure?
Has anyone seen any data or analysis on this topic? My search has yielded very little real info/data. I’d think it would be a simple task to collect that data provided a willing shooter (me), some accelerometers affixed to the skull, and data collected from rounds fired with a firm cheek weld, a light weld and no weld. I suspect the experiment would yield some interesting results.
It would also be interesting to survey the members to get a ROM on the percentage of readers who have experienced a similar injury, their age at the time of the injury, and the percentage of those eye injuries what were to the eye closest to the weapon.
If this analysis has not been done, it sounds like a good quarantine project!
