Glaucoma is the third leading cause of blindness in the United States, following cataracts and macular degeneration. According to the National Eye Institute, more than 2.2 million Americans are affected by this condition. Because vision loss from glaucoma cannot be reversed, prevention and early intervention are critical.

What Is Glaucoma?

Glaucoma is a disease of the optic nerve, often caused by elevated intraocular pressure (IOP). While it can occur at any age, the risk increases significantly after 60. The challenge is that most forms of glaucoma progress silently without early warning signs making regular eye exams essential.

Diagnosis typically involves:

• Measuring intraocular pressure
• Imaging the optic nerve
• Visual field testing
• Corneal thickness measurement
• Examining the drainage angle of the eye

Once diagnosed, treatment usually focuses on lowering IOP through prescription eye drops, oral medications, laser procedures, or surgery. While effective, these options often come with side effects, high costs, and the burden of lifelong management.

Why Explore Green Light Therapy?

Research into light therapy for glaucoma dates back to 1948. Studies revealed that while red light may increase intraocular pressure, green light demonstrated a clear pressure-lowering effect. Patients exposed to short sessions of green light showed reduced IOP levels lasting for several hours.

One landmark study found that a 10-minute exposure to green light at 511 nm wavelength could lower IOP by an average of 5 mm Hg, with results lasting up to four hours. In another trial, patients wearing green-tinted lenses experienced consistent reductions in eye pressure, with even stronger effects when combined with minimal doses of existing medications.

Key findings from early research:

• Green light reduced both average IOP and daily pressure fluctuations.
• More than 80% of patients tested responded positively.
• Benefits were observed even with brief, low-intensity exposure.
• Combining green light with small doses of medication amplified results.

Advantages Over Traditional Treatment

Compared with medication and surgery, green light therapy offers unique advantages:

• Non-invasive and drug-free
• No systemic side effects
• Suitable for early prevention and ongoing care
• Low cost compared to long-term medication or surgical intervention

In Singapore, for example, the 10-year cost of glaucoma medication averaged over US$1,500 per patient, while surgery exceeded US$6,000. By contrast, light therapy devices offer a cost-effective, safe, and repeatable approach for patients and healthcare providers alike.

How Green Light Therapy Is Applied

Treatment is straightforward:

• Short sessions of about 10 minutes
• Daily or regular use recommended
• Safe to integrate into broader wellness routines

Consistency is the key to achieving lasting results. With high-quality devices, patients can access therapy from home or under clinical supervision, depending on the stage of disease management.

The Future of Green Light and Glaucoma

Beyond glaucoma, green light therapy is also being studied for conditions such as migraines and other neurological disorders. Both glaucoma and migraine involve nerve dysfunction, suggesting a possible connection that researchers are only beginning to explore.

As innovation in photobiomodulation expands, new devices could provide safe, accessible options for millions of patients worldwide.
