What symptom is commonly associated with exotropia?

Exotropia, a form of strabismus where one eye diverges outward, often leads to the perception of double vision, also known as diplopia. This occurs because the brain receives two different images from each eye, as they are not aligned properly to focus on the same object. When one eye is misaligned, the brain struggles to integrate the images from both eyes, resulting in double vision as a common symptom.

Blurred vision, while it can occur in various visual conditions, is not primarily associated with the misalignment seen in exotropia. Similarly, glare sensitivity and increased tear production may stem from other eye conditions but are not directly linked to the nature of visual perception problems caused by exotropia. Thus, double vision is the most relevant symptom associated with this condition.
