After 1 week of usage, I called her and wow.. she is so much calmer and her memory has improved! She feels great! SO immediately I am purchasing this for my husband and myself.

After the first week my father with alzheimer's is up and wanting to fix things. This is quiet the change from just sitting in a chair and looking into space.

Benefits of 40Hz Therapy

Research suggests increasing gamma-wave brain activity can activate processes that reduce beta-amyloid plaques, common in aging brains. Reduction of these plaques can improve memory, concentration, and learning. Increased gamma activity can also increase attention and awareness.

Non-Invasive

Safely promotes brain health without the use of medications or invasive procedures.

Backed by Science

40Hz gamma brain therapy is supported by a combination of preclinical and clinical research, highlighting its potential to support cognitive functions.

No Setup

No complicated instructions. Just plug in the device and begin your session immediately.

Precisely Calibrated

Scientifically engineered, Clarity devices deliver light or sound that pulses at exactly 40Hz for best results.

What Is 40Hz Therapy?

Clarity products have light or sound spaced at 40Hz intervals to promote gamma brain waves naturally. New research suggests that light and sound delivered at a certain frequency — 40 flashes or clicks per second — restarts the natural 40Hz gamma rhythm of the brain and improves cognitive functions.

The Science Behind 40Hz Light & Sound Therapy

Gamma waves are specific brain rhythms linked to attention and memory. In cases of cognitive decline, these rhythms are altered and often correlate to the buildup of abnormal protein plaques that interfere with neuron function.

Luckily, recent advances offer new possibilities. Researchers at top brain health institutions have turned their attention to light and sound therapy as a potential solution. They found that exposure to flickering light or sound can encourage the brain to produce healthy gamma waves.

The Science

A Device for Everyone

Gamma Light Therapy delivers science-backed wellness solutions through light and sound. Our Revive Collection uses 670nm red light for calm, sleep-friendly spaces; the Clarity 40Hz Collection stimulates gamma brain waves for cognitive and brain health; and the Soothe Collection’s 570nm green light products encourage relaxation, reduce pain, and ease light sensitivity. Together, these collections provide a holistic, science-driven path to better well-being.
