The Effects of Red Light Therapy on Axial Length Growth and Retinal Blood Flow

: A Non-Invasive Approach to Myopia Management Myopia has become a public health challenge in Asian cities. Its core pathology lies in “excessive axial length growth.”

Clinical studies conducted since 2020 (Repeated Low-Intensity Red Light, RLRL) have shown that exposure to red light at specific wavelengths can effectively slow the rate of axial length growth, providing a new adjunctive treatment for vision preservation beyond defocus lenses and medications.

Med Glow LED is committed to providing professional equipment that meets clinical wavelength requirements, safeguarding the visual health of modern individuals by optimizing retinal-choroidal blood flow.

Clinical Study: How Does Red Light Help Control Myopia?

1. Choroidal Thickening and Axial Length Inhibition

Mechanism of Action: Red light exposure stimulates blood circulation in the choroid, increasing its thickness. The thickened choroid acts as a physical barrier and improves oxygen supply to the sclera, thereby inhibiting pathological elongation of the axial length.

Clinical Findings: Multiple randomized controlled trials involving children and adolescents have shown that low-intensity red light therapy, administered twice daily for 3 minutes each time, can reduce the progression of myopia by more than 70%.

2 . Improving Retinal Hypoxia

Mechanism of Action: Prolonged close-up visual tasks can lead to hypoxia in the retinal microenvironment. Red light (around 660 nm) can directly enhance mitochondrial activity in photoreceptor cells, thereby alleviating hypoxia-induced myopia signaling.

Key Guidelines for Safe Operation and Home Use

Because eye tissue is extremely delicate, Med Glow has established safety standards that are more stringent than those for ordinary household appliances:

*Precise Low-Dose Principle: Myopia prevention and control does not require high-intensity exposure. The Med Glow panel supports precise adjustment of the irradiation distance, ensuring that light intensity remains within the clinically recognized safety range.

*Wavelength Accuracy: Clinical studies are primarily based on narrow-band red light in the 650nm–660nm range.Med Glow uses high-quality chips from the U.S. to ensure no stray light interference.

*Zero Blue Light/Zero UV: Strictly filters out short-wavelength light harmful to the retina, protecting the lens and photoreceptor cells from photochemical damage.

[Safety Reminder]: When using this device at home for myopia prevention and control, it is recommended to do so under the supervision of a professional ophthalmologist and to strictly adhere to the specified operating distance and duration.

Med Glow LED: Protecting the Eyesight of Users Worldwide

Professional protection for users who value the windows to their soul:
