I can understand why it was given to a doctor. "Den Kriegsblinden" refers to what is now known as Bund der Kriegsblinden Deutschlands BKD or Association of War Blind Germany which is now a unified organization, that was founded to take care of soldiers blinded in war or military service and their survivors and they provide that assistance in many ways, as you can imagine. As well as those blinded due to occupational accidents and violence. The transition is depicted in this post card.
The next post card. The Deutsche landsmannschaft "DL" or German Homeland Association which changed it's name in 1908 from Coburger LC was an organization of country teams or university student associations/fraternities. A lot of changes, reorganization and history here. The structure in the background of your post card is that of Coburg castle and since 1873 and even till today have held their annual meetings in Coburg. Honor, friendship and fatherland is the motto.
