You can keep your eyes either open or closed during red light therapy, but for most people, closing the eyes or wearing protective goggles is recommended to reduce eye strain and enhance comfort, especially when using high-intensity devices. Keeping eyes open may provide additional retinal stimulation and support circadian rhythm, but it can also cause visual discomfort for some users. Ultimately, the choice depends on your comfort level, device intensity, and any pre-existing eye sensitivity.
Why the Eyes Matter in Red Light Therapy
Red light therapy (RLT) has become a go-to solution for skin rejuvenation, muscle recovery, and even eye health. But as more people embrace this non-invasive treatment, a common question arises: Should you keep your eyes open or closed during red light therapy? This guide explores the science, safety, and best practices to help you make the right choice for your needs.
What Is Red Light Therapy? How It Works
Red light therapy uses specific wavelengths (typically 600–670 nanometers) to penetrate the skin and stimulate cellular activity, a process known as photobiomodulation. This therapy is widely used for:
- Skin rejuvenation and collagen production
- Reducing inflammation
- Accelerating wound healing
- Supporting eye health and vision
Devices range from handheld wands and panels to full-face masks and clinical-grade machines. FDA-cleared devices, like those from reputable brands, offer added safety and efficacy assurance.
Should You Keep Your Eyes Open or Closed During Red Light Therapy?
You can keep your eyes either open or closed during red light therapy, but most experts recommend closing your eyes or wearing protective goggles for comfort and safety, especially with high-intensity devices.
Overview Table: Eyes Open vs. Eyes Closed
| Eyes Open | Eyes Closed |
|---|---|
| May enhance retinal activation, circadian rhythm | Reduces distractions, promotes relaxation |
| Allows multitasking, reading, or focus tasks | Minimizes eye strain and discomfort |
| Useful for cognitive enhancement | Safer for sensitive users or high-intensity devices |
| Slight risk of discomfort or visual distraction | Preferred for meditation and stress relief |
The Science: How Red Light Affects the Eyes
- Red light therapy is different from harmful UV light. The wavelengths used (600–670 nm) are safe for skin and superficial tissues and far less intense than UV rays. Research indicates:
- Retinal Activation: Some studies suggest keeping eyes open during RLT may activate retinal cells, potentially supporting vision and circadian rhythm.
- Myopia Control: A 2023 clinical study found that low-level red light therapy (650 nm) can slow the progression of myopia and control eye axial growth, especially in severe cases.
- Safety: Unlike UV light, red light does not increase the risk of cataracts or retinal damage when used as directed.
Safety First: Eye Protection and Manufacturer Guidelines
Is Red Light Therapy Safe for Your Eyes?
Red light therapy is generally safe for most users, but prolonged exposure to intense light can cause discomfort or eye strain. Some devices emit blue light or near-infrared wavelengths, which may penetrate deeper and cause mild irritation in sensitive individuals. If you're exploring natural ways to support sleep and relaxation alongside red light therapy.
When to Use Eye Protection
- High-Intensity Devices: Close your eyes or wear protective goggles.
- Pre-existing Eye Conditions: Always use eye protection and consult your doctor.
- Prolonged Exposure: Consider goggles to minimize discomfort.
- Types of Eye Protection:
- Light therapy goggles: Block harmful wavelengths while allowing beneficial light to reach the skin.
- Red light therapy glasses: Filter out specific light, maintaining visibility.
- Masks with built-in protection: Cover the eye area for comprehensive safety.
Pros and Cons: Eyes Open vs. Eyes Closed During Red Light Therapy
Benefits of Keeping Eyes Open
- Retinal Stimulation: May enhance circadian rhythm regulation and support vision.
- Multitasking: Allows reading or other tasks during sessions.
- Comfort: Some users find it easier to relax with eyes open, especially if claustrophobic or anxious.
Benefits of Keeping Eyes Closed
- Relaxation: Reduces distractions, promotes deeper relaxation, and enhances the therapeutic effect.
- Eye Strain Reduction: Minimizes discomfort, especially during long sessions or with bright devices.
- Safety: Preferred for those with light sensitivity or when using high-intensity devices.
Summary Table: At-a-Glance Comparison
| Benefit | Eyes Open | Eyes Closed |
|---|---|---|
| Retinal stimulation | Yes | No |
| Relaxation | Less | More |
| Eye strain risk | Higher | Lower |
| Multitasking | Yes | No |
| Safety (sensitive users) | Lower | Higher |
Best Practices for Red Light Therapy Around the Eyes
How to Use Red Light Therapy Safely
- Prep your skin: Cleanse the area around your eyes to remove makeup or skincare products.
- Position the device: Maintain the recommended distance (usually 6–12 inches for panels, per manufacturer).
- Session duration: Start with 5–10 minutes, increasing gradually as tolerated.
- Eye protection: Use goggles or close eyes, especially for sensitive users or high-intensity devices.
- Monitor comfort: Stop if you experience discomfort, dryness, or irritation.
- Consult a professional: If you have pre-existing eye conditions or are on photosensitizing medications.
- Recovery method: Other trending recovery methods include massage guns
Tips for Maximizing Results
Use FDA-cleared devices for added safety.
Follow the device manual for optimal settings.Stay consistent: Regular sessions yield the best results.
Special Considerations: Red Light Therapy for Eye Conditions
Red Light Therapy for Myopia
A recent clinical trial showed that 650 nm red light therapy can slow the progression of myopia, particularly in severe cases, by controlling eye axial growth and increasing choroidal thickness. This suggests a promising role for RLT in vision support, but long-term safety studies are ongoing.
Red Light Therapy for Macular Degeneration
Early research indicates that red light therapy may help slow the progression of macular degeneration, though more evidence is needed to confirm long-term benefits and safety.
Dry Eyes and Eye Strain
Some users report relief from dry eyes and eye strain with regular RLT sessions, but results can vary. Always consult an eye care professional before starting treatment for any medical condition.
Do I need to wear goggles for red light therapy?
Most at-home devices do not require goggles, but wearing them is recommended for high-intensity sessions, sensitive users, or if you feel discomfort. Always follow manufacturer instructions.
Is red light therapy safe for people with sensitive eyes?
Generally yes, but sensitive users should close their eyes or use goggles for comfort and safety. If you have a pre-existing eye condition, consult your doctor first.
Can red light therapy improve vision?
Some studies suggest red light therapy may help slow myopia progression and support retinal health, but more research is needed.
What wavelength is best for eye health?
Wavelengths between 600–670 nm are commonly used for both skin and eye applications. 650 nm has shown particular promise in myopia control studies.
How close should the device be to my face?
Follow the manufacturer’s guidelines—typically 6–12 inches for panels or masks. Closer distances may require shorter sessions and more eye protection.
Can children use red light therapy safely?
Children should only use RLT under medical supervision, especially for eye-related treatments. Clinical studies on children are limited.
Summary Table: Eyes Open vs. Eyes Closed in Red Light Therapy
| Criteria | Eyes Open | Eyes Closed |
|---|---|---|
| Comfort | May cause strain in some users | Generally more relaxing |
| Safety | Safe for most, but less for sensitive users | Safer for all, especially sensitive eyes |
| Retinal Activation | Possible benefit for circadian rhythm | Less direct benefit |
| Multitasking | Possible (reading, tasks) | Not possible |
| Relaxation | Less (visual stimuli present) | More (fewer distractions) |
Conclusion
There’s no one-size-fits-all answer to the “eyes open or closed” debate in red light therapy. For most users, closing your eyes or wearing goggles enhances comfort and safety, especially with high-intensity devices or sensitive eyes. However, some may benefit from keeping eyes open, particularly for circadian rhythm support or vision-related goals.
Always follow device instructions, listen to your body, and consult a healthcare professional if you have concerns.
