Can the Eclipse emulator be made less blurry when run on retina Mac hardware?
Eclipse's text is high resolution because it is drawn by OS X's APIs. I assume the emulator is simulating the actual resolution of the device, so it might not be able to run at retina resolution.

You can increase the screen's resolution to make the problem less noticeable. Go to System Preferences > Display and select Scaled. This Apple support doc might help: MacBook Pro: Frequently asked questions about using a Retina display

(The only way to get rid of blurriness completely is to run your retina Mac at full resolution.)

Edit - reword because I misread your question.
