Experiencing double vision, also known as diplopia, while wearing contact lenses can be alarming. It's crucial to understand the potential causes and when it's necessary to seek professional help. This comprehensive guide will explore the various reasons behind double vision with contacts, offering solutions and advice on navigating this frustrating issue.
What Causes Double Vision with Contact Lenses?
Double vision isn't inherently caused by contact lenses themselves; rather, they can exacerbate or reveal pre-existing conditions. Several factors can contribute:
-
Underlying Eye Conditions: The most common reason is an underlying eye condition that may not have been previously diagnosed or properly managed. These include:
- Strabismus: This is a misalignment of the eyes, where one eye turns inward, outward, upward, or downward. Contact lenses can sometimes highlight this misalignment, making double vision more noticeable.
- Muscle Imbalance: Problems with the eye muscles responsible for controlling eye movement can lead to diplopia, worsened by contact lenses that might slightly alter the eye's position.
- Eye Infections or Inflammation: Conditions like conjunctivitis (pink eye) or keratitis (corneal inflammation) can cause eye strain and potentially lead to temporary double vision.
- Refractive Errors: While contacts are designed to correct refractive errors (nearsightedness, farsightedness, astigmatism), improperly fitted lenses or incorrect prescriptions can strain the eyes and result in double vision. This is especially true if the prescription is significantly outdated.
- Neurological Conditions: In rare cases, neurological issues affecting the nerves controlling eye muscles can manifest as double vision.
-
Contact Lens Issues: Problems directly related to the contact lenses themselves can also be a contributing factor:
- Improper Fit: Ill-fitting lenses can put pressure on the eyes, causing discomfort and potentially double vision.
- Lens Damage or Debris: A torn or scratched contact lens can disrupt vision and potentially cause diplopia. Similarly, dust or debris under the lens can cause irritation and blurred vision.
- Incorrect Lens Handling: Improperly cleaning, storing, or inserting contacts can introduce irritants and potentially lead to temporary double vision.
Why Do I Suddenly Have Double Vision with My Contacts?
A sudden onset of double vision while wearing contacts warrants immediate attention. It could indicate:
- A new or worsening eye condition.
- A reaction to a new contact lens solution or type of lens.
- Improper lens insertion or removal technique.
- A foreign object under the lens.
How Can I Fix Double Vision Caused by Contacts?
The solution depends on the underlying cause. Here's a breakdown:
- Remove your contacts immediately. This helps to eliminate potential irritation and allow your eyes to rest.
- Clean your eyes and lenses thoroughly. This is crucial to remove any debris or irritants. Ensure you're following proper contact lens hygiene practices.
- If the double vision persists, consult your eye doctor. They can properly diagnose the cause and provide appropriate treatment. This is especially critical for sudden onset double vision.
- Ensure your contact lens prescription is up-to-date. Regular eye exams are essential, especially for contact lens wearers.
- Consider a different type of contact lens. If you suspect an issue with the fit or material of your current lenses, discuss alternatives with your optometrist.
Is Double Vision with Contacts Serious?
While not always serious, persistent or sudden-onset double vision warrants immediate attention. Ignoring it could lead to delayed treatment of an underlying condition, potentially resulting in more serious consequences. Early diagnosis is key.
When Should I See an Eye Doctor About Double Vision?
Consult your eye doctor immediately if:
- You experience sudden double vision.
- The double vision is persistent or worsening.
- You experience double vision accompanied by other symptoms, such as eye pain, redness, or discharge.
- The double vision is affecting your daily activities.
Can Wearing Contacts Cause Permanent Double Vision?
Properly fitted and cared for contact lenses should not cause permanent double vision. However, neglecting an underlying eye condition that manifests as double vision can lead to long-term vision problems.
This information is for general knowledge and does not constitute medical advice. Always consult your eye doctor for diagnosis and treatment of any vision problems. Early detection and intervention are essential for maintaining good eye health.
