The internet is filled to the brim with interesting facts. One recent tweet did more than just share some potentially enlightening information; it was a legitimate eyeopener for some users. The post featured two images, showing the difference between what people with astigmatism see and what those who don’t have it see.
The tweet was posted by the @UnusualFacts6 account, according to a report by Bored Panda. It showed a simple comparison between what individuals with astigmatism – a change in vision caused by a slight curve of the cornea or lens – see and what those who don’t have astigmatism see.
Astigmatism is considered a refractive condition, impacting how light looks for people who have the condition. When a person has astigmatism, the curve of the lens and the shape of the cornea are mismatched, preventing light rays from bending correctly and creating a blurry image.
In most cases, people with astigmatism also have other site issues, such as myopia (nearsightedness) or hyperopia (farsightedness).
While refractive errors are common, impacting approximately 43 percent of the world’s population, many Twitter users who saw the tweet were unaware they had the condition or that others didn’t see light as they do. Others were merely surprised at the difference.
Depending on the degree of the mismatch, astigmatism can usually be correct with the right glasses lenses or contacts that are designed to address the issue.
