Mai Nguyen,

PhD, UC Berkley | Optoceutics CEO 

Hi! Welcome to Optoceutics.  

If you are reading this then you probably have some real concerns regarding cognitive health for yourself or a loved one.

I’m Mai Nguyen. I’m the CEO of Optoceutics – the team behind the EVY LIGHT®. 

I’m a neuroscientist with a PhD from UC Berkley but my interest in brain health goes back to my childhood. Over time, it become more personal as my parents’ cognitive health began to decline.

At Optoceutics, our mission is to lead the way in advancing the frontiers of neuroscience, and to create a future where our light-based brain technology becomes a beacon of hope for those seeking improved cognitive function and optimal brain health.

Judge The EVY LIGHT® For Yourself 

100% Risk-Free

We’re happy to give you plenty of time to use the EVY LIGHT® without risk because you’ll want to be sure you experience the benefits.
Using the EVY LIGHT® is like going to the gym. You shouldn’t expect to see any noticeable changes the first day or even the first week, although some users do report better sleep and more energy in the short term.
With consistent use - at least one hour/day - it takes an average of two months to notice definite cognitive benefits such as memory improvement and better focus. 
For that reason, we have a three-month, no-questions-asked refund policy. We want to ensure you are happy with everything the EVY LIGHT® will do to support your brain health.

Explore The Science Behind EVY LIGHT®

OptoCeutics is founded on academic and clinical research. 
40Hz gamma wave stimulation has been shown to reduce general cognitive decline like memory loss, inability to focus, or remain alert and organized throughout the day.

How much would you pay for a healthier brain? 
A knee replacement costs upwards of $30,000, just so you can walk. So, what would you expect to pay for brain health that gives you better focus, memory, mood, and sleep?
If a knee is worth $30,000, how much is a brain is worth? 
$60,000? More? 
Thankfully, you won’t pay anything close to that for the EVY LIGHT®
How about the price of a coffee once a week? Does that seem reasonable for a healthy brain?
