The Eyes of Texas is a shop in the Buddyeen that sells cheap donated replacement eyes. The source is supposed to be from Texas in North America.
The source of the shop's name is the Fight Song of University of Texas at Austin, "The Eyes of Texas (Are Upon You)". The song, sung to the tune of "I've Been Working On The Railroad", is about how its graduates are expected to do great things. The cruel pun implies that Texas in this timeline is so bad off that some people have to sell their eyes (or other organs) to make a living.
