You’re Feeling Nauseous
When you are processing visual information each eye creates a separate image and then your brain amalgamates those individual images into one seamless picture.
However, if one of your eyes is a bit fuzzier than the other your brain processes incorrectly and produces a more wonky image. This can result in you feeling rather nauseous. “If one eye has a stronger prescription than the other eye, all of a sudden your brain is seeing two separate images,” says Dr. Garg.
“It’s hard for the brain to resolve to put those images together.” In response, you could start feeling vertigo, nausea, or double vision, she says.
