Seeing Double: Examining the 4 Causes of Double Vision

Request Appointment

Your eyes transmit various images and visual information to your brain day in and day out. However, there are some instances when your vision fails. While there are minor and temporary eye issues, such as eye fatigue, that can easily be fixed by taking a short break from visual activities, there are visual problems that are longer-lasting and should be a cause for concern. Depending on the duration and severity, double vision is one of the more serious eye problems that need to be closely monitored.

Seeing Double: Examining the 4 Causes of Double Vision

Your vision therapy center, Clear View Vision Care, lists four possible causes of double vision.

What Is Double Vision?

Double vision or diplopia is a vision irregularity wherein a person sees two images instead of one. The second image can have a different orientation compared to the original image. Diplopia can affect either or both eyes. Double vision is often the result of eye muscles that can’t properly reconcile visual information as one coherent image. You might be seeing double due to the reasons below.

1. Brain Injury

A brain injury, as a result of a blow to the head, can cause abrupt diplopia. Other brain-related causes are strokes, tumors, swelling and aneurysm. If necessary, your eye doctor may refer you to a neurologist for further diagnosis and treatment.

2. Dry Eyes

Patients who suffer from dry eyes syndrome may experience diplopia fairly frequently. Seeing double due to dry eyes can be addressed by using over-the-counter or prescription eye drops. Consult your eye care specialist if double vision persists even after undergoing various treatment methods for dry eyes.

3. Refractive Surgery

Patients who have undergone refractive surgery may experience double vision for quite some time after the procedure. The condition is expected to improve within weeks or months of the surgery.

4. Cataracts

As of 2016, more than 22 million Americans over the age of 40 are afflicted with cataracts. This number is projected to balloon up to 30 million by the year 2020. Cataracts cause the lens of your eyes to become cloudy, thus producing a ghostly image or double vision.
