You look up at the sky, and suddenly, you can see phantom squiggles, or shapes resembling worms or tangles of thread superimposed on your field of vision.
These objects are commonly called eye floaters. But what causes them? And are they benign, or can they sometimes signal a serious problem?
I wrote about eye floaters in this April 2019 Your Health Questions column for Good Times: ‘What Are Eye Floaters?’
A big thank-you to the interviewees who so generously shared their time and expertise:

- Dr. Andre Stanberry, a clinical associate professor and clinic director at the University of Waterloo’s School of Optometry and Vision Science in Waterloo, Ont.
