A Message from Mai Nguyen, PhD, CEO at Optoceutics.

A warm welcome to you!

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

Please allow me to tell you a little more about myself, our company, and our innovative product, the EVY Light®.

As a neuroscientist with a PhD from UC Berkeley, my passion for brain health stems from a lifelong fascination with cognitive performance and a heartbreaking personal journey witnessing the decline of my parents’ cognitive abilities.

We developed the EVY Light® to address critical issues of cognitive decline.  Cognitive decline happens for many reasons. It could be age, dementia, Alzheimer’s disease or other factors.

Read on to learn about EVY Light® and how it works.

It’s Time to Support Your Cognitive Health

Whether you forgot why walked into a room or your loved one can’t remember who you are, you’re in the right place.

Users of EVY Light® support their cognitive health at all stages. It’s always a good time to support your cognitive health!

“It’s okay, Ellen. It’s me Ron, your husband.”

A loved one who can’t remember who you are. Sadly, it’s a reality that happens every day. 

Whether you forgot why walked into a room or your loved one can’t remember who you are, you’re in the right place. Users of EVY Light support their cognitive health at all stages, from prevention in their 40s to advanced Alzheimer’s disease and dementia. It’s always a good time to support your cognitive health!

The question we get most is:

"Why are gamma waves so critical for cognitive health?"

Many Studies show a decrease of gamma brain waves in people who are experiencing cognitive decline.
It's well known that gamma waves play a pivotal role in essential cognitive functions such as mental focus, memory retrieval, problem-solving, information processing, attention and awareness. 
When gamma waves are strong and fast, cells can transmit stronger signals across all areas of the brain. This is the hallmark of a sharp mind.

Effortless Gamma Wave Stimulation

EVY Light® effortlessly stimulates healthy gamma wave activity in your brain to promote essential cognitive health.
Put the EVY Light® in front of you for an hour a day while you work, watch TV, eat, read, etc. to provide the gamma wave stimulation it needs.
You don’t have look directly at EVY Light® for it to work. Simply have it close by, within your field of view.
