A-E Dispatches

LED Therapy isn't just for aesthetic concerns and dermatology treatments. Focused light energy devices are being used by optometrists for eye concerns. 

As ever; the information provided here isn't medical advice, but rather a summary of reported LED uses from credible sources. 

LED Therapy in Optometry: Photobiomodulation Via a Dual-Wavelength Approach 

LED therapy is gaining traction in optometric care as a noninvasive treatment for dry eye and demodex-related conditions. By emitting low-intensity light at targeted wavelengths, it can modulate biological activity without damaging tissue. 

1) Red / Near-Infrared Light for Inflammation and Dry Eye

Red (630–670 nm) and near-infrared (810–850 nm) light is proven to reduce inflammation. In addition, it stimulates mitochondrial function in meibomian glands, enhancing ATP production.  This improves gland activity and tear film stability in patients with MGD. Unlike IPL (intense pulsed light), red light is non-thermal and safe for sensitive skin types. When used with IPL, it can extend symptom relief and reduce post-treatment inflammation. The typical irradiance range applied is 5 to 100 mW/cm² 

2) Blue Light for Demodex Management

Blue light (405–470 nm) targets demodex mites and associated bacteria. It produces reactive oxygen species that damage microbial cells, reducing mite populations and inflammation. Optometrists report cleaner lid margins and better tear stability. Blue light is painless and non-contact. The typical irradiance range applied is 10 to 50 mW/cm² 

Suitable Low Level Light Therapy Devices 

There are dozens of suitable professional LED devices available on the market. Many aesthetic LED devices can provide the required optometry specifications. The most important technical criteria we suggest in selecting a device are:

• Red, infrared, and blue wavelengths with customizable treatment settings. These are the clinically proven LED therapy treatments, other colors aren't proven to add efficacy

• Face-focused LED devices. There is no need for a large LED panel of 3 feet or more

• Suitably powerful - and adjustable - irradiance levels including the range of 5 to 100 mW/cm²  

• Price: If you are considering a device that costs over $35,000, be clear on what performance attributes - or marketing benefits - you're paying a premium for.  

One device that fits these criteria that we provide on AeonEx is the Omni Photodynamic System.
