Health Matters: What’s Causing Your Double Vision?

When images start to look different and blurred, doctors say you could be experiencing double vision. “The images can be separated horizontally, vertically, or on an angle, or it can be a slight blurring on the object if the double vision is very minimal,” said Lee Health pediatric ophthalmologist Dr. Shauna Berry.

Dr. Berry says several causes can lead to double vision. “It can be either an issue with the nerve that supplies the muscle of the eye. It can be a problem with the junction between the nerve and the eye muscle or it can be an issue with the eye muscle itself,” she said. But other things like thyroid problems, autoimmune diseases, high blood pressure, diabetes, even brain tumors can cause double vision. “There are two different types of double vision—we have monocular versus binocular. Monocular double vision is when you have either eye closed and you are still seeing double vision. With binocular double vision that usually goes away with either eye closed and that’s usually because the brain is getting two different images by the eyes being misaligned,” Dr. Berry said. Depending on the cause, doctors may recommend glasses, medications, surgery, or simple lifestyle changes to improve double vision.
