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.

Did you know an estimated 1.9 million neurons and 14 billion synapses are lost per minute during a stroke? That’s why every second counts. Anyone can have a stroke, but your chances increase if you have certain risk factors. That’s why the best way to protect yourself or your loved ones from a stroke is to know the risks and how to manage them. You can make changes to your lifestyle to lower your risk of stroke by asking yourself the following questions: 1. Is my blood pressure normal? High blood pressure is the leading cause of stroke and the most important controllable risk factor. If you’ve had a stroke, lowering your blood pressure can help prevent future strokes. 2. Can I quit smoking? Smoking damages blood vessels, clogs arteries and raises blood pressure — doubling your risk of stroke. If you want to reduce your risk of stroke and heart attack, quitting smoking is the first step — and Renown can help you with this. Learn more: Renown Health Quit Tobacco Program. 3. Do I make time to exercise 30 minutes a day? Many studies link consistent exercise habits with lower stroke risk. Also, being overweight contributes to high cholesterol, high blood pressure, heart disease and diabetes, all increasing your stroke risk. You don’t need to run a marathon — just commit to making time to move each day. 4. Do I regularly eat processed food and sugar? Eating less cholesterol and fat, especially saturated and trans fats, may reduce the fatty deposits (plaque) in your arteries. Also, eating five or more servings of fruits and vegetables per day may reduce your stroke risk. If you are diabetic, follow recommendations to get your diabetes under control.

Stroke is unfortunately common, with 1 in 5 American women experiencing it each year. When it comes to a stroke the phrase “time is brain” speaks to the urgency of getting rapid care. In fact, a woman may lose nearly 2 million neurons per minute of oxygen loss to the brain. The Renown Health Comprehensive Stroke Center experts share the importance of timely treatment and how stroke symptoms can differ in women. Women and Stroke – Surprising Symptoms  Each year stroke affects more women than men. Even more concerning, women are less likely to recover from a stroke. The following non-traditional, less common, warning signs can be common in women: Hiccups with chest pain Sudden disorientation, drowsiness, confusion or a general altered mental status Nausea or vomiting A sudden headache that feels like the ‘worst headache of your life’ Unusual chest pain (especially with hiccups) Body numbness or weakness, such as an arm or leg suddenly ‘falling asleep’ Fainting or loss of consciousness Stroke Diagnosis The first step is neuroimaging by CT scan. This allows for rapid identification of any bleed, and also assists in determining candidacy for the early clot busting medication. MRI brain imaging is much higher resolution, and can better determine the core stroke size, assisting in prognosis and recovery. Since strokes have several different origins, an inpatient workup is essential to determine the underlying cause. Whether the stroke is secondary to plaque in the large vessels, clots being thrown in the setting of atrial fibrillation (an abnormal heart rhythm), or small vessel disease from years of uncontrolled vascular risk factors (high blood pressure, smoking, high cholesterol, diabetes), determining the cause is essential to implementing a management plan to reduce risk for further strokes. Quick Treatment for Stroke is Key Early recognition of stroke symptoms and seeking prompt attention is paramount. There are interventions that can be instituted to minimize the stroke and increase likelihood of recovery, but only if a patient presents to the hospital early. A clot busting medication, called tPA, can be given to patients with stroke if given within 4-5 hours from time of onset. Renown Regional Health Center is designated as a Comprehensive Stroke Center, the highest level of stroke certification available. To earn the designation of comprehensive stroke center, a hospital has to meet stringent requirements, including biannual on-site evaluations. This includes care for ischemic stroke patients (lack of blood flow), hemorrhagic stroke patients (bleeds), and determining the underlying cause to guide secondary stroke management prevention. Stroke Symptoms Remember “B.E.F.A.S.T.” to recognize the symptoms of a stroke below: B – Balance Being off balance or dizzy, is common. E – Eyes An eyesight change such as blurring or double vision may occur. F – Face droop One side of the face, or lip, droops A – Arm weakness Does one arm drift down? S – Speech Talking may slur or sound strange. T – Time Time to call 911. Call an ambulance immediately if you or anyone else, experiences any of these symptoms.
