Due to their unique evolution, a majority of Efrosians are born blind. When traveling off their homeworld, they often need to use devices to see, such as special glasses.
It is rumored that addressing Efrosians by name is an insult to their religion, though obviously those in the public light don't always follow this. Other races are known to refer to Efrosians as Ateniods or Atenids, the same way some races call humans "Earthers" or "Terrans".

The name for this species never appeared in any script, dialogue, or production graphic. It was noted, however, in Paramount's initial publicity photos for Star Trek IV.
The name "Efrosian" was invented by Kirk Thatcher, an associate producer on Star Trek IV, in honor of unit production manager Mel Efros. Probably based on the publicity photos the name was then picked up and used in the Star Trek IV Sourcebook Update to the FASA role-playing game system to describe the species. Although never formally adopted by Paramount beyond the publicity photos (the Star Trek Encyclopedia, for example, goes out of its way to avoid using the name) the name has been popular with fans.
In 2003 Decipher issued a book for their role-playing game called Aliens in which the species name was given as "Atreonid". There has been unconfirmed speculation that this was at Paramount's request, although the name "Atreonid" has not appeared in any Star Trek productions.
The Cast and Crew of Tales of the Seventh Fleet came up with the logic of Efrosians being also known as Ateniods or Atenids, the same way some races call humans Earthers or Terrans. It seemed like the best solution to combining the references of FASA and Decipher.
