Maximize tear production by supporting both your lacrimal and vagus nerves

Patented Parasym Plus Eyes™ is the only compound scientifically proven to nudge the lacrimal and vagus nerves to safely support normal tear production.

Lacrimal Nerves                |                  Vagus Nerve

Invented by an eye doctor and researcher in dry eye disease (DED) and the parasympathetic nervous system.

Groundbreaking Science

Never before has tear production been viewed as a localized manifestation of systemic (body-wide) health!

Support normal tear production by supporting autonomic health.

Our Tears

Ocular tears do more than just provide moisture! They play an important role in protecting the eye from infection, they allow a smooth, clear surface for good vision, and they continually nourish the ocular surface.

To help maintain ocular health, tears contain over 2,000 different molecules, including over 1,500 proteins as well as growth factors, lipids, antioxidants, mucins, electrolytes, and enzymes.

Artificial tears cannot be a substitute for natural tears.

We must maximize the ability to produce our own, natural tears while controlling inflammation.

This Works Via Two Mechanisms

The Lacrimal Nerves

Tear production is under tight neural control and is a complicated neurological process. The parasympathetic nervous system is the major pathway for tear production. It works via stimulation of the lacrimal gland by the parasympathetic lacrimal nerves.

The lacrimal nerves communicate with the lacrimal gland to produce tears as needed. The nerves release a neurotransmitter (acetylcholine) that then lands on receptors in the lacrimal glands. This signals the glands to produce tears.

Parasym Plus Eyes™ works by supporting acetylcholine — the neurotransmitter needed for tear production.

The Vagus Nerve

By maximizing acetylcholine, Parasym Plus Eyes™ also supports the vagus nerve. Your vagus nerve is the anti-inflammatory nerve of the body. Normal inflammation is important for healthy and comfortable eyes!

What does the vagus nerve do?

  • The vagus nerve controls inflammation. This nerve also:
  • Allows normal digestion and bowel movements
  • Triggers normal stomach acid production
  • Communicates with the gallbladder to release bile
  • Communicates with the pancreas to release digestive enzymes
  • Slows heart rate and breathing when relaxation is appropriate

Vagus Nerve Function & the Parasympathetic Nervous System

From the Inventor

“When studying chronic dry eye, I noticed patterns in many of the patients. Sluggish digestion, brain fog, large pupils with light sensitivity, and fatigue – in addition to dry eye. These types of symptoms suggest a deficiency of acetylcholine. When addressed properly, not only do dry eyes improve, but so does overall wellness. This presentation involves the autonomic nervous system, and because there is no blood test for this, it must be recognized by presentation – which is subtle and easy to miss.”

Dr. Diana Driscoll, inventor of Parasym Plus Eyes

Dr. Diana Driscoll, Inventor

Parasym Plus Eyes™ is the only compound patented to simultaneously support both:

The Vagus Nerve (the nerve that controls inflammation)

The Lacrimal Nerves (the nerves that stimulate tear production)


In the past, tear production was seen as an ocular function only.

When viewed as just one aspect of body-wide autonomic function, supporting tear production changes dramatically.

Support autonomic health for normal tear production and overall wellness.

What interferes with the release of acetylcholine?

Aging, nerve damage, and inflammation all negatively affect the release of acetylcholine and ultimately result in dry eyes. Parasym Plus Eyes™ is patented to work around all of these issues by directly affecting the receptors – it does not depend upon a functioning nerve.

What Does It Feel Like To Have Dry Eyes?

Dry eyes are more than a nuisance. They can cause significant discomfort, pain, and even visual disability. Symptoms of dry eyes include:

  • A burning sensation of the eyes
  • Difficulty wearing contact lenses
  • Blurry vision
  • Difficulty driving at night
  • Itching of the eyes
  • Feeling like you have something in your eyes
  • Accumulation of mucus in or around the eyes
  • Redness of the eyes
  • Pain from dull or very bright light


“For years literally I have suffered with dry, inflamed, red irritated eyes. It’s amazing after 30 years of chronic eye problems, multiple specialist appts, lots of eye medications, I’m so much better.”

Joanie H.

“I couldn’t believe I got so caught up with work and life and forgot to get my Parasym Plus! Big mistake! My eyes were a mess mornings waking up with wetness and eye crud!!! It was overwhelming! Then I thought I hadn’t taken my Parasym Plus! Folks this stuff is magic in a bottle! Don’t be without it!!!”

Steve S.

“My dry eyes feel a lot better after only a few weeks!

I can’t wait to see long term what the product will do!!! I am impressed !!!”

Caroline F.

“I had dry eyes and after taking Parasym Plus the doctor said my eyes were hardly dry anymore!”

Pami G.

“We’ve seen a decrease in dry eyes, a decrease in fatigue, a decrease in our heart rates, and a decrease in brain fog. This supplement has helped us so much.”

Tracy H.

“Wow! What a difference! No more dry eyes or dry mouth. It helps my cognition, my gut, and my emotions. This one is worth it!”
