Wearing contact lenses during an MRI is not recommended due to potential safety risks and image clarity issues.
Understanding MRI Scans
MRI, or Magnetic Resonance Imaging, is a medical imaging technique used to visualize internal structures of the body. It employs powerful magnets and radio waves to generate detailed images of organs, tissues, and other structures. Unlike X-rays or CT scans, MRIs do not use ionizing radiation, making them a safer option for many patients. However, the strong magnetic fields used in MRIs can interact with certain materials, including metal. This is why understanding what you can and cannot wear during an MRI is crucial.
The primary purpose of an MRI scan is to detect abnormalities within the body. It’s commonly used for diagnosing conditions related to the brain, spinal cord, joints, and soft tissues. The images produced are incredibly detailed and can help healthcare providers make informed decisions about treatment options.
The Role of Contact Lenses
Contact lenses are a popular vision correction method that many people rely on daily. They provide a convenient alternative to glasses and come in various types, including soft lenses, rigid gas permeable lenses, and specialty lenses for specific conditions. While they offer benefits like improved peripheral vision and freedom from fogging or breaking, they also raise concerns when it comes to medical imaging procedures like MRIs.
One significant concern regarding wearing contact lenses during an MRI is the material composition of some lenses. Many contact lenses contain materials that may be susceptible to magnetic fields or could interfere with the imaging process. Additionally, if a patient experiences any adverse reactions while in the MRI machine—such as discomfort or irritation—removing contacts can become problematic.
Why You Should Avoid Contact Lenses During an MRI
Several reasons exist for avoiding contact lenses during an MRI scan:
1. Safety Concerns
The primary reason for not wearing contacts during an MRI is safety. Some contact lenses contain metallic components or coatings that could be affected by the strong magnetic fields in the machine. This interaction could potentially lead to lens distortion or even injury if a lens were to dislodge.
2. Image Clarity Issues
Wearing contact lenses may compromise the quality of the images produced during an MRI scan. If there’s any distortion caused by the lens material or if the lens shifts position during the procedure, it could lead to unclear images that may hinder accurate diagnosis.
3. Discomfort During Scanning
Patients often lie still in a confined space for extended periods during an MRI scan. If someone wears contacts, they might experience dryness or discomfort due to prolonged wear without blinking adequately. This discomfort can distract from remaining still during imaging.
4. Risk of Infection
In some cases, wearing contact lenses can increase the risk of eye infections if not handled properly before and after the procedure. Given that MRIs often require some level of cleanliness and sterility in medical environments, this risk should not be overlooked.
What Are Your Options? Alternatives to Contacts
If you rely on vision correction but need to undergo an MRI scan, several alternatives are available:
1. Glasses
Wearing glasses is typically recommended instead of contact lenses for individuals undergoing MRIs. Glasses do not have metallic components that could interfere with imaging quality or pose safety risks within the magnetic field.
2. Discuss With Your Medical Team
Before your appointment, discuss your vision correction methods with your healthcare provider or radiologic technologist. They can offer personalized recommendations based on your specific situation and needs.
3. Temporary Vision Solutions
If you don’t wear glasses regularly but need vision correction for your MRI appointment, consider using temporary options like disposable glasses available at many optical shops or online retailers.
The Procedure: What Happens During an MRI?
Understanding what happens during an MRI can help alleviate anxiety about the procedure itself:
1. Preparation: Before entering the scanning room, you’ll typically be asked to change into a hospital gown and remove any metallic items such as jewelry or belts.
2. Positioning: You’ll lie down on a movable table that slides into the MRI machine’s opening (the bore). Comfort is key; cushions may be provided for support.
3. Scanning Process: Once you’re positioned correctly, the technician will leave the room but will continue monitoring you through cameras and intercom systems.
4. Imaging: The machine will make loud noises as it captures images; this is normal! You might hear knocking sounds as it works through different sequences.
5. Completion: The entire process usually takes between 20 minutes to over an hour depending on what areas are being scanned.
During this time, it’s crucial to remain still so that clear images can be captured without blurring.
A Closer Look at Contact Lens Safety Materials
It’s essential to understand what materials are commonly found in contact lenses and how they might react in an MRI setting:
| Contact Lens Type | Material Composition | Potential Risks During MRI |
|---|---|---|
| Soft Lenses | PVC (Polyvinyl Chloride), HEMA (Hydroxyethyl Methacrylate) | Might absorb moisture; potential distortion. |
| Rigid Gas Permeable Lenses | PVP (Polyvinyl Pyrrolidone), Fluoro-silicone acrylate | Might shift position; possible discomfort. |
| Scleral Lenses | Scleral GP materials (various polymers) | Larger size may cause pressure points; risk of dislodging. |
| Toric Lenses (for astigmatism) | Bifocal materials with weighted designs. | Weight distribution may shift; unclear imaging. |
| Cosmetic Lenses | Dyes integrated into soft lens material. | Dyes may react poorly under certain conditions. |
Understanding these materials helps illustrate why wearing contacts during an MRI isn’t advisable.
The Importance of Communication with Healthcare Providers
Open communication with healthcare professionals is vital when preparing for any medical procedure:
- Discuss Your Vision Needs: Let your doctor know about your reliance on contacts so they can guide you appropriately.
- Ask Questions: Don’t hesitate to inquire about any concerns regarding your comfort level during scanning.
- Follow Pre-Procedure Instructions: Adhering strictly to guidelines ensures both your safety and optimal imaging results.
Remember that each patient’s needs differ based on their unique circumstances.

Frequently Asked Questions
Can you wear contacts during MRI scans?
No, wearing contacts during an MRI is not recommended. The strong magnetic fields can interact with certain materials in contact lenses, potentially leading to safety risks and image clarity issues. It’s best to remove them prior to the procedure for optimal safety and imaging results.
What are the safety concerns of wearing contacts during an MRI?
The primary safety concern is that some contact lenses may contain metallic components that could be affected by the magnetic field. This interaction can cause distortion of the lens or even physical injury if a lens dislodges during the scan.
How do contact lenses affect MRI image quality?
Contact lenses can compromise the clarity of MRI images. If the lens material distorts due to magnetic fields or shifts position during imaging, it can lead to artifacts in the images, making it difficult for healthcare providers to obtain accurate diagnostic information.
What should you do with your contacts before an MRI?
Before undergoing an MRI, it’s advisable to remove your contact lenses. You should bring a case and solution for storage. If you’re unsure about what to do, consult your healthcare provider for specific instructions regarding your vision correction needs.
