“There’s been a couple of people who’ve called in saying that they looked at the eclipse and now they’re concerned,” he said.

After the 2017 total solar eclipse crossed North America, there were approximately 100 patients across the United States and Canada with “eclipse-related retinopathy,” according to a report by the American Astronomical Society, citing survey data.

Phil Hooper, an ophthalmologist in London, Ont., and president of the Canadian Ophthalmological Society, is hopeful that eclipse watchers took the necessary precautions to not put their vision in jeopardy.

“If we look at the experience worldwide in other eclipses, typically it’s not a major problem,” Hooper said in an interview with Global News Tuesday.
