Description

Clarity devices utilize cutting-edge technology, inspired by the latest scientific research and clinical studies on the benefits of 40Hz light therapy. Every Gamma Clarity device undergoes meticulous calibration and testing using precise scientific oscilloscopes, ensuring accurate frequency and optimal performance. Recent research reveals that the 40Hz flickering light from the Gamma Clarity device stimulates healthy gamma rhythms in the brain. Everything you need is included to begin experiencing the benefits of gamma light therapy right away. Research suggests that boosting gamma-wave brain activity can activate vital processes that help reduce the accumulation of beta-amyloid plaques, a hallmark of aging brains often linked to cognitive decline. These plaques are believed to disrupt normal brain function, but their reduction may support improvements in memory, concentration, and learning abilities. Additionally, heightened gamma activity has been associated with enhanced attention, mental clarity, and overall awareness, offering significant cognitive benefits for those seeking to maintain or improve brain health as they age. Gamma waves are unique brain rhythms that play a crucial role in cognitive functions such as attention, memory, and learning. These rhythms help coordinate the activity of neurons, enabling efficient communication within the brain. However, in cases of cognitive decline, such as Alzheimer’s disease and other neurodegenerative conditions, these rhythms become disrupted. This disruption is often linked to the accumulation of abnormal protein plaques, like beta-amyloid, which interfere with neuron function. Researchers at leading brain health institutions have begun to explore the potential of light and sound therapy as innovative tools for restoring healthy brain activity. Studies have shown that exposure to flickering light and sound at 40Hz can stimulate the production of natural gamma waves, supporting the brain’s ability to combat the formation of harmful plaques. These advances open up exciting possibilities for enhancing brain function and slowing the effects of cognitive decline. Gamma Light Therapy offers science-backed wellness.

Spend a Little More and Purchase This One. It Works as Described.
Mom loves it! It produces a consistent, steady 40hz 'shimmering' that is not offensive. Mom says she is sleeping better and from my observation, she seems to be more focused and cognizant. This works far better than the $50 flickering light bulb I purchased first. That cheaper product does not produce a consistently timed strobe pattern and it can be irritating. I would think the lack of consistent 40hz strobing defeats, or at least reduces its effectiveness. I recommend spending more money and purchasing this product. It does what it says it does. ... show more

Long lasting, easy to use 40hz. Lamp.

I have been using this light now for over 10 years. I used to have it on almost non-stop after I was recovering from surgery. The light is sleek and pulses at a 40hz. Frequency. This was the first company I found selling these for public use and I am so happy with the product. The flickering is similar to what I noticed in beginning stages of meditation. With this lamp on and the lights off, it was a very simple and encouraging experience to help continue with therapy and I highly recommend! ... show more

40hz light works for helping my cognition and long term memory
This is a second unit for another room, and I like it except it doesn't have the choice to choose a more daylight color. The light that it emits is pretty yellow for my liking, but otherwise the quality of the unit seems very sound and it gives me the ability to move from room to room and still have the flicker. I noticed some reviewers found the flicker annoying, but that may have to do with placement. It should be in your peripheral vision and the flicker is far less noticeable than when looking straight at it. It also takes time to adjust to it, I think. I definitely recommend for people struggling with memory and cognition. It's a very helpful tool. ... show more

A Life-Changing Light
I’m 70 years old and have been very concerned about my poor memory for over 10 years. When my husband shared with me the research about this product, I figured it wouldn’t hurt to try it. I am so glad I did – it’s been life-changing! For the past 7 months, I’ve spent one hour a day using the light (keeping it in my peripheral vision). While sitting by it, I never use other screens (phone, iPad, TV). The results have been dramatic. I can now consistently recall information that I know I would not have remembered before using the light therapy. Because I had struggled with my memory for so long, I know the frustration and hopelessness of not being able to remember things. Before using the light, on a scale of 1-10, I would have rated my memory a 2 or 3. Now I rate it a 7 or 8. That’s how transformative this light has been for me. I’ve had at least 5 friends buy this light and they’ve all seen improvements in their memories, although I don’t think as profoundly as I have. I highly recommend this product. ... show more

Great lamp except that it does not meet my standard for durability
I like this lamp — it supports my processing and mood by reducing brain fog. Yeah, I like it a lot. However, after purchasing it 14 months ago — and using as directed on approx 85% of mornings — it has already burned out.

Flashing light
The light flashes and is hard to keep your eyes open. I bought it for my mom and she keeps her eyes closed the whole time. She hates it
