Green Eyeglasses Improve Anxiety and Wellness in Fibromyalgia Patients

By Pat Anson, PNN Editor

Fibromyalgia is well known as one of the most difficult chronic pain conditions to treat. The Food and Drug Administration has approved a handful of medications for fibromyalgia, but many patients find them ineffective in treating the muscles aches, joint pain, fatigue, anxiety and other symptoms that are common in fibromyalgia.  

Researchers at Duke University may have found an easy way to reduce some of those symptoms without the use of drugs. In a small study of fibromyalgia patients being treated with opioids, those who wore eyeglasses with specially tinted green lenses reported a significant improvement in their anxiety and overall sense of wellness. And while their pain levels were unchanged, their use of opioids declined.

“My research has been focused heavily on finding alternatives to opioids for pain management,” says lead author Padma Gulur, MD, Executive Vice Chair of the Department of Anesthesiology at Duke University. “One of the things we discovered early on was that there were visually mediated triggers for pain. We definitely could see that with headaches, but also that it could actually impact pain itself, the pain pathways. While we still don’t fully understand the mechanism of how pathways for pain get activated with visual mediation, it definitely does happen.

“We narrowed it down over some years to the hypothesis that with green light, particularly in the green spectrum, there was an opportunity where it was influencing pain, both chronic pain and acute pain.”

Previous research has found that green light therapy has a calming effect on the brain and is useful in treating fibromyalgia and migraines. But in those studies, participants were confined to a room where they were immersed in green light and told to avoid activities like watching TV or using their cellphones.

Gulur thought there must be an easier way to experience the benefits of green light.

“People want pain relief, but they also want to live their lives. And spending hours and hours in a room or exposure takes away from that quality of life,” she told PNN. “On the other hand, wearing eyeglasses is something we’re all very comfortable doing and, thankfully these days, colored eyeglasses are all the thing.”

Gulur and her colleagues studied 34 fibromyalgia patients who were randomly selected to wear various shades of eyeglasses at least four hours a day for two weeks: 10 patients wore blue eyeglasses, 12 wore clear eyeglasses and 12 wore green eyeglasses.

Their findings, presented this week at the annual meeting of the American Society of Anesthesiologists, showed that participants who wore green eyeglasses were four times more likely to have reduced anxiety than those in the other two groups, who reported no reduction in anxiety. They also reported feeling better.

“We found that although their pain scores remained the same, those who wore the green eyeglasses used fewer opioids, demonstrating that their pain was adequately controlled,” said Gulur, who noted that patients who wore the green eyeglasses asked if they could keep them at the end of the study.

“They didn’t want to give them back. We had no trouble getting the blue and the clear back, but none of them wanted to return the green glasses.”

Unfortunately, they had to give them back. The eyeglasses are specially formulated to filter a specific wavelength on the green light spectrum and were needed for further study. You can’t buy the glasses online or at your local drug store. At least not yet.

Gulur and her team are planning further studies with green eyeglasses on patients with diabetic neuropathy and chronic back pain.

Are You Skinny Fat?

By Barby Ingle, PNN Columnist

I recently was visiting my primary care doctor for my wellness physical -- something I haven’t done in many years. This was a comprehensive exam that took a look at all of my physical symptoms, including body fat to bone density ratio.

I have heard since childhood that a bit of prevention can add years to your life. A healthy lifestyle is not something many of us are taught, but it is something we can start at any age and gain benefits from. Take heart disease, for example. It’s the number one killer in the United States and accounts for one in every four deaths. Many chronic pain patients have cardiovascular, balance, breathing and body fat challenges. Treating these health problems is difficult, so preventing them from starting is key.

When was your last wellness physical? Did you talk about prevention?

My medical records from a one-hour examination with a nurse and two hours with the doctor were 18 pages long. I was checked for routine things such as my vitals, medication use and past medical history. Risk factors were also discussed such as alcohol and smoking. I do neither and never plan to anyway.

My doctor devotes more time to each patient so that we can go beyond normal primary care practices. He and his staff perform a comprehensive advanced health screening and diagnostic tests that have been shown to help detect issues earlier. The results help give a clearer view of your overall health.

We went over a lot as I have been a patient of his for about 15 years now. He is my lead treatment provider and knows my case better than all of my other doctors.

One of the most interesting things was him saying I look totally normal and healthy. Yes, that is called invisible illness. But after looking at all of my blood and diagnostic test results, he got deep into his analysis. He said I am “skinny fat.”

What is skinny fat you ask? It’s a totally unscientific term used to describe a person who appears to be a healthy weight, but actually has a high body fat to muscle ratio. For example, my arms are stronger and have more muscle mass than my legs.

My entire life I was eating poor. I was the one eating mac ‘n’ cheese, cookies, cake and soda. I was an athlete and had hypoglycemia until I was 29. Then I developed central pain syndrome (also known as full body Reflex Sympathetic Dystrophy) and went from being extremely active and working out daily to bedbound or in a wheelchair for almost 7 years. I have been limited in workouts and physical activities for the past 8 years, going in and out of remissive states.

It is important to remember that the scale doesn’t paint the whole picture as to how healthy you are. You can be obese and look totally healthy or have great muscle tone and thicker bones. Looks can be deceiving. Some studies suggest that up to 35 percent of people with obesity may be metabolically healthy.

The number on the scale doesn’t paint the whole picture of someone’s health. Being skinny fat is a prime example. In my case, I am metabolically obese, yet in a normal weight range. Although I am not diabetic or even pre-diabetic, my doctor said I still need to pay attention to being skinny fat and make changes. I need to get my fat levels down and my muscle level up.

Preventative measures like these need to be added to my lifestyle, despite having chronic pain. Not doing so can lead to health problems like insulin resistance, high blood pressure, high cholesterol and an increased risk for blood clotting. This study gives some great information on the risks of being skinny fat from a medical standpoint.

By the time I left my doctor’s office, I had a detailed action plan.

My plan is to get my muscle mass up and my fat mass down over the next 3 months. I don’t know if this is wishful thinking being chronically ill, but I am going to give it my best shot. The tips my doctor gave include moving more with cardio walks, stationary bike exercises, and lifting two-pound weights -- which should be enough to tone my muscles without triggering a pain flare. He also advised me to eat more protein and stop eating all of the processed food that filled my diet.

My doctor will redo the testing in 3 months and let me know what other changes I need to make or if this was enough.

When you see another patient who is super skinny, know that they may be struggling with their body composition as well, and they may actually not be as healthy as you are. I have struggled with being too low weight in the past.  Now I am in a normal range, yet too fat!

It seems like we all have something to work on. I wish that as a child I was taught these important preventative and life-prolonging lessons.
