Is Red Light Therapy Safe For Your Eyes?
17.09.24
Red light therapy (RLT) has become a hot topic in the wellness space, but many people wonder if it's safe for the eyes. Unlike UV light, which can damage both skin and eyes, red and near-infrared light operate at longer wavelengths and are far less likely to cause harm. In fact, RLT may actually provide eye health benefits, particularly for conditions like glaucoma and age-related macular degeneration (AMD). Studies show that red light stimulates mitochondrial activity, aiding cell regeneration, and reducing inflammation in the retina.
How Red Light Therapy Affects the Eyes
Red light and near-infrared (NIR) light work within specific wavelengths—red light typically ranges between 600 to 700 nanometers, while NIR ranges from 700 to 1,100 nanometers. Unlike UV light, which has shorter wavelengths and higher energy, red and NIR light penetrate deep into the body’s tissues. This allows them to promote cellular repair and reduce inflammation without damaging the skin or eyes.
Can Red Light Therapy Help with Eye Conditions?
Several studies suggest that RLT is not only safe for the eyes but may also offer therapeutic benefits. Here's how it can help with two common eye issues:
Age-Related Macular Degeneration (AMD): This condition affects the retina, leading to vision loss. Red light therapy helps by boosting mitochondrial function, which can slow the progression of AMD by encouraging cell repair in the retina.
Glaucoma: Another eye disease, glaucoma damages the optic nerve and can result in vision impairment. RLT’s ability to reduce inflammation and stimulate cellular activity may help protect the optic nerve, although more research is needed in this area.
The Importance of Eye Safety During Red Light Therapy
While RLT is generally safe, users often report mild discomfort from the brightness and heat, especially during treatments that are focused on areas near the eyes. To avoid this discomfort, it’s recommended to wear protective eyewear. Most RLT devices include safety instructions, but it’s always a good idea to consult a healthcare provider before starting any treatment that involves the eyes.
Home-use red light devices should be chosen carefully, ensuring they are of high quality and designed with safety in mind. Baxter Blue's range of Red Light Therapy devices are all TGA Certified, FDA registered, SAA approved and hav an ISO13485 certificate. Cheaper, poorly constructed devices might not be as safe or effective.
Key Research Supporting Red Light Therapy’s Safety for the Eyes
A growing body of research supports RLT’s benefits for eye health. For example, a study published in Scientific Reports found that red light therapy enhances mitochondrial function in the retina, potentially aiding in the treatment of AMD. Similarly, research in the Journal of Biomedical Optics concluded that near-infrared light could reduce inflammation without harming the eyes.
However, it's important to note that research is ongoing, and while early findings are promising, consulting with a healthcare provider is always recommended when considering red light therapy, especially for sensitive areas like the eyes.
Conclusion: Is Red Light Therapy Safe for the Eyes?
Red light therapy is generally safe for the eyes and may even offer therapeutic benefits for conditions like glaucoma and AMD. With that said, it's wise to wear protective goggles during sessions to avoid any discomfort from brightness. While the therapy carries minimal risk, it’s always best to seek guidance from a healthcare professional before starting treatments around the eyes.
