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.

The Healthy Nevada Project (HNP) is one of the most visible genomic studies in the United States, and guess what? Renown Health powers it! The Healthy Nevada Project (HNP) aligns with Renown's goal to do the best for our patients. The genomic study is at no-cost for Nevadans and gives participants insight into different genetic traits, including results on three prevalent and serious health conditions known as CDC Tier 1 conditions. CDC Tier 1 Conditions Include: Hereditary Breast and Ovarian Cancer Syndrome (HBOC) Lynch Syndrome Familial Hypercholesterolemia (FH) Not only does HNP give participants insights into their genetic background, but it also facilitates Renown's ability to study population health. Research lays the foundation for the future of medicine, and Renown's HNP is on the cutting edge of genetic research. We do this by providing skilled researchers access to studies for the diseases that currently have limited treatment, including nonalcoholic steatohepatitis liver disease or NASH. For example, the observational NASH study helps researchers understand genetic links to the disease. Make an Appointment to Get Screened If you haven't already, join the over 55,000 HNP participants and make an appointment to have yourself screened. You can schedule a screening appointment through MyChart. Click “Schedule an Appointment" and select Research Appointment - Genetic Screening. Prior to your appointment, please complete e-Check-in and complete your consent form.

Colorectal cancer is the number two cancer killer in Nevada, only second to lung cancer, yet it is also one of the most preventable. Still, in 2020, 20.7% of Nevadans said they had never been screened for this deadly disease, according to the Nevada Cancer Coalition. At the start of the COVID-19 pandemic, unfortunately many healthcare services were halted, including colorectal cancer screenings. Those delays in screenings can lead to delays in diagnoses of colorectal cancer, resulting in poorer outcomes. Per the American Cancer Society, if colorectal cancer can be found early the relative 5-year survival rate is approximately 90%. Screening is key, and it is important to engage in preventative care. Even if you have no personal or family history of colorectal cancer, ask your doctor about colorectal risk factors and when to start screening, and if you’re up to date on your screenings, talk to loved ones and make sure they are too. According to the American Cancer Society, most colorectal cancer cases are found in those without a family history. This month let us help raise awareness for colorectal cancer and the importance of routine, life-saving screenings. To learn more, we spoke to Renown Health oncology nurse Christina Alsop, APRN. What is Colorectal Cancer Colorectal cancer is a disease in which the cells in the colon or rectum grow out of control. It usually forms from precancerous polyps, or abnormal growths, in the colon or rectum, which can become malignant without presenting any symptoms. How do Screenings Work Screening tests like stool tests, colonoscopies and others can detect these precancerous polyps, so they can be removed by a physician before turning into cancer. Screening tests can also find colorectal cancer early, resulting in better treatment outcomes. As of 2021, the U.S. Preventative Services Task Force recommends adults begin colorectal cancer screenings beginning at age 45, through 75. Screening methods include a blood stool test, which needs to take place every year or a colonoscopy, which takes place every 5-10 years. Healthy Habits Can Help Stave Off Risk Routine screenings are the only way to determine colorectal health, yet some healthy habits may reduce your risk for colorectal cancer. These factors include maintaining a healthy weight, being physically active, eating a diet rich in fresh fruits, vegetables and whole grains, limiting alcohol intake and not smoking.

You might think worsening eyesight is inevitable as you age. But the truth is, there are easy things you can do to keep your eyes in tiptop shape for years to come. Clear vision is an essential part of overall health and there are daily habits we can adopt to keep our eyes seeing clearly. Mitchell Strominger, M.D., a registered ophthalmologist with Renown Health specializing in pediatric ophthalmology and neuro-ophthalmology, offers some everyday tips to keep you focused on eye health. Know your family’s vision history Look to your parents and grandparents for clues about the future of your eye health. Were they near-sighted at a young age? Do they have a history of eye crossing or a lazy eye? Did they develop glaucoma or macular degeneration (AMD)? Some genes have a strong association with eye health, specifically macular degeneration. AMD is a leading cause of blindness worldwide and the top cause of vision loss and blindness for Americans over 65, according to the Centers for Disease Control and Prevention (CDC). Also be aware certain medical conditions, such as diabetes, high blood pressure and liver disease, increase the risk of long-term eye problems. Receive regular vision screening exams Children under three need vision screening examinations by their pediatrician. A medical concern or family history warrants a comprehensive eye examination by a pediatric ophthalmologist (or general ophthalmologist or optometrist who has experience with children) per the American Academy of Ophthalmology (AAO). Vision screenings should occur every two years throughout adolescence unless pain, eye crossing, difficulty seeing the board or reading, or other eye concerns occur. In adulthood the risk of eye problems increases over age 40, so the AAO recommends regular dilated exams. When your pupils are dilated it allows your eye care professional a more accurate view of your retina and optic nerve, located in the back of your eye. This allows them to look for AMD or other eye problems. Eye diseases can be caught at their earliest stages during a dilated eye exam. “It is especially important to have your child evaluated as soon as possible if there is any concern for eye crossing or lazy eye,” says Dr. Strominger. “The visual system develops in the early years so intervention, whether it be glasses, eye patching to strengthen the vision in one eye, or eye muscle surgery is critical. Children at risk include those who are born premature, have development abnormalities, genetic disorders such as Downs syndrome, or a strong family history and should be evaluated at a young age. Often small problems are not clearly evident and cannot be picked up on routine screening examinations in the pediatrician’s office.” Block the sun, improve your vision Everyone knows not to stare directly into the sun, but indirect ultraviolet (UV) sun rays can cause serious harm over time. According to the National Eye Institute, sunglasses (or a protective UV tint) are a daily must to protect your eyes from: Cataracts (a clouding of the eye’s lens causing blurred vision) AMD - macular degeneration Pterygium (a tissue growth over the white surface of the eye that can cause astigmatism) Look for sunglasses which block 99 to 100 percent of both UVA and UVB rays. You still need sunglasses if your contact lenses block UV rays. Sun rays can damage your eyelids and other tissue not covered by contact lenses. Wearing sunglasses protects your entire eye area. Eat colorful meals Your eyes need vital nutrients to keep them healthy including vitamin C, zinc, beta carotene and copper. A diet filled with citrus fruits and a variety of vegetables provide these essential nutrients. Regularly filling up on fish high in omega-3 fatty acids (salmon, tuna, sardines) may reduce your risk of AMD and help maintain your eye health. Green, leafy vegetables (kale, spinach, collard greens) containing lutein and zeaxanthin are also a must for your dinner plate. Water your eyes Eyes, like the rest of your body, need plenty of water to prevent dehydration. Make sure you stay hydrated and steer clear of smoke to avoid dry eyes and irritation. Hours staring at the computer screen can also make your eyes feel dry or tired. Try regularly refreshing them with lubricating eye drops. Taking frequent computer breaks is also important. Follow the 20/20/20 rule: every 20 minutes, look at an object 20 feet away from you for 20 seconds. Eye makeup can also lead to dry eye as the glands at the base of the eyelashes may become clogged, causing dry eye. Make sure all eye makeup is hypoallergenic and is thoroughly removed with a gentle cleanser for the delicate eye area each day. Stop Smoking (or never start) Smoking is harmful to every part of your body, including your eyes. It's not only linked to cancer and heart disease but also cataracts, AMD, dry eye, optic nerve problems and many other problems. Smoking during pregnancy can also harm the eyes of the unborn child. If you currently smoke take steps to quit and your entire body will benefit.
