A tweet has been shared more than 22,000 times which claims to compare how people with and without the eye condition astigmatism see the world at night.
Astigmatism is a problem with focusing light accurately onto the retina, due to an irregular curvature of the cornea or abnormalities in the lens of the eye.
“Astigmatism is when the cornea is slightly curved rather than completely round,” Unusual Facts tweeted last week.The image on the left shows blur and lens flare from the lights of cars and traffic lights, while the scene on the right does not.Some Twitter users questioned whether the photos were an accurate representation of the condition.
“I've seen this light streaking effect whenever my wipers are running, and the aligned trail of water alters the headlights in front of me.”“This explains why a friend of mine doesn't understand when I tell him ‘lens flare’ is real life,” Julie Blackwood tweeted.CTVNews.ca reached out to the Canadian Association of Optometrists for its take.
