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.

September is National Healthy Aging Month, which is described by Healthy Aging Magazine as a “month designed to focus national attention on the positive aspects of growing older.”   What does healthy aging mean to you? If you're like most people, you're looking forward to removing the negative from your life – negative energy, thoughts, people and activities that don't contribute to your best life.   While we remain focused on ridding ourselves of the negatives, we can forget about ways to strengthen the positive parts of our lives. Dr. Shruti Basho, a family medicine physician at Renown Health’s senior-focused medical group, provides us with five positive behaviors to focus on to improve happiness and life satisfaction.  Healthy Aging in 5 Easy Steps  Connect – Humans are naturally social creatures! Build connections with friends, family, colleagues and neighbors. Strong interpersonal connections help enrich your life with new experiences and opportunities. Having a support system to call upon in both times of need and times of celebration is priceless, especially as you age. Forming these bonds helps you stay healthier and happier well into your aging journey. Joining the Sterling Silver Club is a great place to meet more people in the community who want to live a healthy, fulfilled life just like you. Be Active – Regular exercise, particularly as you grow older, is vital to increase and maintain your endurance, strength and balance. But exercise doesn’t have to be a chore! Pick a physical activity that you enjoy – whether it be enjoying a nature walk, taking a power weightlifting class or anything in between. Being active will also help you build strong connections with others. If you need a workout buddy in your neighborhood, Nextdoor is a great resource to find people who live right around the block from you and may be looking for their next exercise partner.   Take Notice – Curiosity and mindfulness can be an impactful motivator in positive cognition and behavior as you age. Like a child, see the wonder and beauty of the world. Notice the things around you – the weather, the landscape, the mood and the feelings of people. According to Harvard Medical School, changes in the aging brain "enable us to become better at detecting relationships between diverse sources of information, capturing the big picture, and understanding the global implications of specific issues.” By taking notice, it’s easier to learn to appreciate the things that matter.  Keep Learning – Engaging with lifelong learning is one of the best ways to keep your mind active. Keep trying something new! Challenges keep you on your toes and increase your confidence and excitement in your day. Don’t know where to start? EPIC (Educational Programs Inspiring the Community) offers a diverse personal enrichment and professional development curriculum at Truckee Meadows Community College ranging from art classes to accelerated training certificate courses.  Give – Be generous with your time, your knowledge and your talents by giving to friends, family and the community when you have the capacity. Lending yourself to others doesn’t have to be taxing – saying thank you and even just giving someone a smile can change the course of someone’s day. If you’re looking for a hands-on way to give back, Nevada Volunteers is a great place to find volunteer opportunities near you. Renown Health is also always looking for volunteers who are passionate about making an unforgettable difference to the people and communities we serve.   Practice these five tips to improve happiness and quality of life at any age.
