Double vision occurs when you see two images of a single object. These images may appear side by side, on top of each other, or slightly offset.

This can make reading, driving, and everyday activities more difficult and uncomfortable.

In Calgary, where clear and stable vision is important for both work and daily mobility, double vision can significantly impact safety and performance.

At Eye Check Calgary, we treat double vision as an important symptom that requires careful evaluation, especially if it appears suddenly or worsens over time.

COMMON CAUSES OF DOUBLE VISION IN CALGARY

Double vision can result from a range of underlying issues. Some are related to how the eyes work together, while others may involve eye health or broader medical concerns.

Common causes include:

• Eye coordination or alignment problems (binocular vision issues)
• Uncorrected or changing prescriptions
• Dry eye affecting visual clarity
• Muscle imbalance affecting eye movement
• Nerve-related or neurological conditions

The cause can vary depending on whether the double vision affects one eye or both eyes.

TYPES OF DOUBLE VISION: MONOCULAR VS BINOCULAR

Understanding the type of double vision can help guide diagnosis.

Monocular double vision:

• Present when only one eye is open
• Often related to issues within that eye, such as surface irregularities or refractive errors

Binocular double vision:

• Occurs only when both eyes are open
• Typically related to eye alignment or coordination problems

This distinction is an important part of determining the underlying cause during an eye exam.

WHEN DOUBLE VISION MAY REQUIRE IMMEDIATE CARE

Not all cases of double vision are urgent, but some situations require prompt medical attention.

Seek immediate care if you experience:

• Sudden onset of double vision
• Double vision accompanied by headache or dizziness
• Difficulty speaking or moving
• Vision changes after a head injury
• Persistent double vision that does not resolve

These symptoms may indicate a more serious underlying condition and should be evaluated as soon as possible.

HOW EYE EXAMS IN CALGARY IDENTIFY THE CAUSE

A comprehensive eye exam is the most effective way to determine the cause of double vision.

At Eye Check Calgary, we evaluate:

• Eye alignment and coordination
• Focusing ability
• Eye movement and muscle function
• Overall eye health using advanced imaging

These assessments help us understand whether your symptoms are related to visual function, eye health, or require referral for further evaluation.

HOW DOUBLE VISION IS MANAGED

Management depends on the underlying cause identified during your exam.

Possible approaches may include:

• Prescription lenses to improve visual clarity
• Prism lenses to help align images
• Vision therapy to improve eye coordination
• Management of dry eye or surface issues
• Referral to a specialist when needed

Each case is unique, which is why personalized assessment is essential.
