Quantum optics may turn this rare visual phenomenon into an eye test

Modern life depends on quantum physics.

It makes technologies such as GPS navigation, MRI scanners and computer chips possible.

Now, the same science may also lead to a new way to test the health of our eyes.

A University at Buffalo-led team has used a technique from quantum optics to make a little-known visual pattern produced inside the eye easier to see—potentially opening the door to a new way to test retinal health. ...
