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.

Raquel was 33 when she was diagnosed with breast cancer. It was April 2023, when she found a lump in her breast and was referred to the William N. Pennington Cancer Institute. After comprehensive imaging, she was diagnosed with invasive lobular carcinoma, which is a type of breast cancer that begins in the milk-producing glands of the breast. Between June 2023 and January 2024, she received a total mastectomy, chemotherapy and radiation at Renown Health. “Breast cancer is uncommon in women under 40, but any woman with a mass or lump in her breast should have an exam by a physician and imaging at any age,” said Dr. Lee Schwartzberg. In fact, according to the Centers for Disease Control and Prevention (CDC), only 9% of all new cases of breast cancer in the U.S. are found in women younger than 45. “It was a pretty scary diagnosis, but I’ve been led by great people through the process,” she said. “They were so helpful and there for me throughout the chemo and radiation.” Raquel's journey through breast cancer treatment at the William N. Pennington Cancer Institute was marked by the exceptional care provided by the Renown Health team, including nurses, nurse navigators, therapists, support teams and providers. Among the dedicated professionals, Dr. Michelle Chu and Dr. Lee Schwartzberg played pivotal roles in Raquel's diagnosis and subsequent treatment plan. Their expertise, compassion and commitment to patient care left an indelible impact on Raquel's experience. Their thorough examination and comprehensive approach ensured that Racquel received the best possible care for her invasive lobular carcinoma. In addition to the care provided at Renown, Raquel greatly benefitted from being connected with a mentor by Dr. Chu. This mentor, Kayla, had undergone a similar diagnosis and treatment plan, and at the same age Raquel. They texted and called each other throughout Raquel’s treatment, providing additional support through a challenging time. As of January 2024, Raquel is done with her treatment and continues to see her care team for follow-up appointments. “I’m through the worst and ready to rebuild my life,” Raquel said. To help celebrate this milestone, Nevada Athletics invited Raquel to receive the game ball at a Nevada Men’s Basketball game. She was joined on the basketball court for this special recognition by her husband, Raul; mother, Arlene; and two daughters, Ryleigh and Rhiannon. Racquel's journey is not only a testament to her resilience but also a tribute to the invaluable contributions of Dr. Chu and Dr. Schwartzberg in guiding her towards triumph over breast cancer.
