"Somebody" is a big fool
: First of all not every blind qualifies for the transplant, it is done for specific problem only.
: Secondly calculation is wrong- only one eye transplant is done per blind person not both so it takes less than 6 days even if we assume all blinds qualify for the transplant
: Thirdly not all deads qualify for donations eg: diabetes etc
Lastly: everyone should donate for this good cause even if above calc is ok or not
Finally: What about organ transplant, especially brains from WD Gann, Alex Elder, Edward Magee, Woodeis, Linda & likes
