Can Wrong Prescription Glasses Cause Headaches?

An eye doctor holds up two pairs of glasses, one with clear frames and the other with tortoiseshell frames.

When it comes to vision correction, the right prescription glasses can make all the difference in your daily comfort and overall quality of life. But what happens when your prescription is off? Can wrong prescription glasses cause headaches? 

The short answer is yes, the wrong prescription can cause headaches. In this blog, we’ll explore why that happens, how to recognize the signs, and what you can do to ensure your glasses provide you with clear vision and eye comfort.

Understanding the Link Between Vision & Headaches

The eyes and brain work in tandem to process visual information. When your eyes are not properly aligned or focused, your brain has to work harder to interpret what you’re seeing. This extra effort can lead to a range of symptoms, including headaches.

When you wear glasses with the wrong prescription, some issues can arise such as:

  • Eye Strain: Incorrect lenses force your eyes to work harder to focus, leading to eye strain. This strain can extend to the muscles around the eyes and the forehead, resulting in headaches.
  • Blurred Vision: Wearing glasses that do not correct your vision properly can cause blurred or double vision. This forces your brain to compensate, which can be mentally exhausting and trigger headaches.
  • Incorrect Alignment: If the optical centres of your lenses do not align with your pupils, it can create visual distortions. These distortions can cause discomfort and headaches as your brain tries to make sense of the skewed images.

Common Symptoms of Wrong Prescription Glasses

A young person sits on their couch with a computer in their lap, rubbing their eye and holding their glasses.

A headache is a common symptom of wearing incorrect prescription glasses, but it’s not the only one. Here are some other signs to watch for:

  • Eye Fatigue: Feeling tired or fatigued after short periods of reading or screen time can indicate that your glasses are not providing the right level of correction.
  • Blurred Vision: Persistent blurry vision, especially after wearing your glasses for a while, is a clear sign that your prescription may be incorrect.
  • Dizziness or Nausea: Visual distortions caused by incorrect lenses can lead to dizziness or a feeling of nausea, particularly when you move your head or change focus quickly.
  • Double Vision: Seeing double images or ghosting effects can occur if your glasses are not properly calibrated to your prescription.
  • Eye Discomfort: Experiencing discomfort or pressure around your eyes, nose, and temples is another indicator that your glasses might not be the right fit.

Why Prescription Accuracy Matters

Ensuring your prescription is accurate is crucial for both the comfort and clarity of your vision. 

The right prescription provides clear and comfortable vision, reducing the strain on your eyes and brain. Wearing incorrect prescription glasses over an extended period can lead to chronic eye strain, potentially causing more severe headaches and even vision problems.

From reading and driving to working on a computer and enjoying hobbies, having the correct prescription enhances your ability to perform daily activities without discomfort.

What Causes Incorrect Prescriptions?

Several factors can contribute to an incorrect prescription such as:

  • Changes in Vision: Your vision can change over time due to aging, health conditions, or lifestyle factors. Regular eye exams are essential to keep your prescription up to date.
  • Errors in Eye Exams: Occasionally, mistakes can happen during eye exams, leading to an incorrect prescription. This is why it’s important to communicate any discomfort or issues with your optometrist.
  • Poor Lens Manufacturing: Errors in the manufacturing process of your lenses can result in incorrect prescription glasses. Ensuring you get your glasses from a reputable provider can minimize this risk.
  • Frame Fit & Lens Alignment: The fit of your frames and the alignment of your lenses are crucial. If your glasses do not sit correctly on your face, the optical centres may not align with your pupils, leading to visual distortions.

Steps to Ensure the Right Prescription

To avoid the discomfort and headaches associated with incorrect prescription glasses, follow these steps:

1. Schedule Regular Eye Exams

Regular eye exams are essential for maintaining optimal vision health. Adults should have an eye exam at least once every two years, or more frequently if recommended by their optometrist.

2. Communicate with Your Optometrist

During your eye exam, be sure to discuss any vision changes, discomfort, or headaches you have been experiencing. This information can help your optometrist fine-tune your prescription.

3. Choose Reputable Providers

Get your glasses from reputable optical providers who ensure high-quality lens manufacturing and proper frame fitting.

4. Follow-Up Adjustments

If you experience discomfort or headaches after getting new glasses, do not hesitate to return to your optometrist for adjustments. Sometimes, minor tweaks to the lens alignment or prescription can make a significant difference.

5. Consider Lens Options

Discuss with your optometrist about different lens options, such as anti-reflective coatings, blue light filters, or progressive lenses, which can enhance comfort and reduce eye strain.
