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.

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.

An arthritis diagnosis doesn’t mean your exercise routine has to end. In fact, a consistent routine can actually improve mobility. Although stiff and painful joints can make it difficult to keep moving, staying active is essential for easing pain. October 11 is World Arthritis Day, so we asked Michelle Higgins, MPT at Renown Physical Therapy & Rehab some advice about exercising with arthritis. According to the Arthritis Foundation, arthritis affects one in five adults and 300,000 children. As a matter of fact arthritis is the nation’s leading cause of disability. Your joints certainly don’t need to suffer when you exercise. In general exercise is actually necessary for those with arthritis. Not only does it reduce joint pain, but it also increases strength and flexibility. Furthermore those adopting a regular exercise routine also have more energy, deeper sleep and find it easier to maintain a healthy weight. “Exercise is a necessary component to managing your arthritis,” says Higgins. “Consistent participation in an exercise program has been shown to promote long-term pain relief, increased body function and an improved quality of life. Alternatively, a lack of exercise can actually increase joint pain or stiffness and eventually lead to long term disability and suffering.” Exercising With Arthritis Exercise truly is the most effective non-drug arthritis treatment available for reducing pain and improving movement. And it can even include daily activities like gardening, dancing or walking your dog. Of course talk to your doctor or physical therapist about what exercises fit into your specific treatment plan. With this is mind, the four specific components below are important to an effective arthritis exercise program: Range of motion Moving joints through their full available range of movement is important. This frequently increases function and decreases joint stiffness and pain. For this reason, aim to complete these exercises daily. Examples include bending, straightening, and rotating specific joints, or static and dynamic stretching. Strengthening These exercises target muscles supporting and protecting our joints and bones. Strengthening is also necessary for weight control, so two-to-three sessions per week are recommended. In order to allow your body to adapt, begin with light resistance and start slow. Strength exercises include weightlifting and using resistance bands. Low-impact aerobic exercise Aerobic exercise is certainly necessary for overall well-being, weight management and heart health. Aim for two-to-three sessions a week. Low-impact exercises include walking, swimming, cycling, elliptical machine exercises and water aerobics. Balance Good balance is also vital for an effective arthritis program. On the positive side, solid balance prevents falls by increasing your ability to stay upright whether you are moving or sitting still. Likewise, it improves your confidence with walking and daily activities. In order to keep excellent balance, incorporate daily balance exercises. Examples of balance exercises include the use of an exercise ball, Tai Chi and exercises such as standing on one foot. Start Slow, Finish Strong As you begin your exercise program, remember to listen to your body. Start slowly – it can take several weeks for your body to adjust to exercise. Consult your doctor, or physical therapist, if you experience increasing pain or swelling which doesn’t go away with rest. Above all, incorporate fun and motivating activities so you’ll stick to them long term and improve your results.
