Are Blue Light Glasses Necessary?
Since the COVID-19 pandemic, more people are working from home than ever before, leading to a rise in digital screen time. Between spending eight or more hours staring at a computer screen, and some downtime hours spent looking at a smartphone or watching TV, it’s almost inevitable to feel some adverse effects at the end of a day. Blue Light Effects vs. Digital Eye Strain Blue light is all around us, and the most natural source comes primarily from sunlight. Other forms of blue light are artificial and emitted by digital screens including LED TVs, smartphones, tablets and computers. Surprisingly enough, research shows blue light can actually have health benefits such as promoting alertness, boosting memory and cognitive function, elevating mood and regulating circadian rhythm. However, studies indicate that an excess in blue light exposure can lead to depletion of melatonin production, a hormone that regulates our sleep cycles. In today’s eyewear industry, blue light glasses are one of the more popular items purchased by consumers. Companies who sell the glasses claim they help with reducing or eliminating digital eye strain, while also increasing natural melatonin secretion to get a good night’s sleep. Other than their slight yellow tint to filter out blue light, they mostly look like regular glasses and come in many different stylish frames. You can find blue light glasses through various eyewear retailers. Most adults have experienced digital eye strain. Common symptoms of digital eye strain include headaches, blurred vision, irritated eyes, and fatigue. Many believe that digital eye strain is caused by overexposure to blue light, but medical vision experts say that is not the case. “Digital eye strain is related to how we use our digital devices, not the blue light coming out of them,” says Mitchell Strominger, MD, a neuro and pediatric ophthalmologist with Renown Health. Do Blue Light Glasses Even Work? Since blue light glasses aren’t medically proven to help with digital eye strain, you’re probably wondering if they’re even worth using. “If you’re one to binge a TV show or scroll though social media before bedtime, the blue light from those digital screens can disrupt your circadian rhythm and cause you to lose sleep, which can ultimately lead to other adverse health effects,” says Dr. Strominger. “While more research is still needed, some studies have shown that blue light glasses may prevent melatonin suppression and increase quality of sleep. There is no harm in trying them out and seeing if they work for you.” As for preventing digital eye strain, Dr. Strominger shared several helpful tips: Try using the 20-20-20 rule, which entails looking away from your screen and looking at an object 20 feet away for at least 20 seconds. Sit at an arm’s length (about 25 inches) away from your screen. Adjust the brightness and contrast of your screen, especially before bedtime. There is a night mode setting on most smart phones you can use. Reduce your screen time whenever you can and give your eyes a break.

Keeping Your Brain Healthy, No Matter Your Age
It’s true there is no cure for dementia, yet studies suggest your life choices today can reduce brain decline in the future. How important is diet to brain health? Food is the foundation of your body. Fats, carbs and protein provide the energy for your cells and metabolism. So the quality and amount of food you eat directly affects your brain. Specifically, researchers are paying special attention to the link a high sugar diet and/ or an unhealthy fat diet may have on your brain. Your brain on sugar According to the Alzheimer’s Association, when too much sugar is in the bloodstream for long periods of time, it can damage the brain cells. Many people with diabetes may develop brain abnormalities, and these changes may increase chances of dementia — research is still being done to understand this connection. Many U.S. adults have prediabetes with blood sugar higher than normal. Insulin resistance often leads to diabetes. Insulin resistance has been linked to metabolic syndrome, which is a precursor for cardiovascular and cerebrovascular disease (heart attack, stroke). Some signs of metabolic syndrome include: Large waist size (40 inches or more for men, 35 inches and up for women) Low HDL (good) cholesterol level Higher than normal blood pressure — 130/85 and above Current research suggests too much sugar in the blood causes inflammation, which can damage brain cells. High carbohydrate foods, such as sweetened beverages, chips, white rice, white potatoes, bagels, cereals and desserts, have been shown to raise blood sugar. Although anyone can get diabetes, Hispanic Americans and African Americans are at greater risk.

Powerlifting through MS Diagnosis
When Tabitha Cox received a diagnosis of multiple sclerosis (MS), she was in shock, denial and felt that she was too strong for something like this to be happening to her. As the disease progressed, Tabitha realized she needed to do what she could to stay as healthy as possible. “I heard, ‘You have a quarter-size lesion on your brain,'” recalls Tabitha Cox. “At that moment, that was literally all I heard come out of her mouth.” Tabitha’s official diagnosis was multiple sclerosis (MS), an unpredictable, often disabling disease of the central nervous system that slowly debilitated her mom. “I was numb,” says Tabitha. After her diagnosis, Tabitha went on with her life as if the disease was nothing more than a doctor’s diagnosis. However two years later, Tabitha realized something wasn’t right and sought care at Renown Institute for Neurosciences – Brain and Nerve Care. Her form of MS was aggressive, and her doctor recommended treatment right away.
