What a wonderful opportunity we have to give our corneas or other organs to another person when we die. The thing is that we must make our wishes known in advance. That is very easy to do. In Virginia, when we renew our driver's license we can check the box indicating that we'd like to give the gift of sight or of life itself to another person by donating our organs.
I have checked that box. I have the words "Organ Donor" with the little red heart on my driver's license. I encourage you to do the same.
