SAN FRANCISCO (AP) — Schools across the United States are facing shortages and long delays in getting laptops and other equipment needed for online learning. They are this year’s most crucial back-to-school accessories. Part of the reason is high demand and disruptions of supply chains that have jammed production of laptops and Chromebooks made by Dell, HP, Lenovo and other brands. Schools say another critical reason is the Trump administration’s recent sanctions on Chinese companies that have exacerbated massive backlogs. Educators nationwide worry that computer shortfalls will compound inequities. They also warn of headaches for students, families and teachers. 679

Screen time has become a common concern during the pandemic, as many school districts turn to online learning. That has doctors telling parents to pay close attention to their children's eyes. "Everybody, adults and kids, can develop computer eye strain. That's mostly because there's a decrease in the blink rate, incomplete eye closure with the blink rate," said Dr. Cate Jordan, a pediatric ophthalmologist with the American Association for Pediatric Ophthalmology and Strabismus. Dr. Jordan says eye drops or a warm compress can help children with eye irritation because of increased technology use. But most of all, make sure your eyes get some relief from a screen."In between classes, take a break. Look out a distance and take a couple hard blinks. I really recommend really taking a few hard blinks because it pumps the oil glands and really helps lubricate the eyes," said Dr. Jordan.Stephen Reid is the co-founder of Hue Eyewear. Reid and his wife founded their blue light glasses company when they noticed their children suffered side effects from too much screen time. "With the amount of time we're spending on our screens right now, especially during the pandemic, we need to make sure that we protect ourselves," said Reid.Reid says the glasses protect children and adults from blue light that's emitted from computer, tablet, phone and even television screens. "My children use the glasses. Ever since we started the company they've been using them and they tell me their eyes are less strained and I can feel it, too," said Reid.Dr. Jordan says more studies need to be done on the effectiveness of blue light glasses. Our eyes naturally protect against harmful rays that could affect our eyesight, she adds. "If you've already bought them and a child feels better and wants to use them, then absolutely there's no harm in wearing them. But there's no need to have every child wearing blue light glasses," said Dr. Jordan.Dr. Jordan says too much blue light at the end of the day can disrupt your circadian rhythm, or sleep cycle, so she recommends children make an effort to avoid screens at least two hours before bed time. 2150

SAN FRANCISCO (AP) -- San Francisco supervisors are set to approve new legislation to discourage racist 911 calls that they say expose people of color to dangerous run-ins with police.Supporters say people need to think twice before calling 911 on someone who is barbecuing, jogging or stenciling "Black Lives Matter" at a home.The legislation is called the Caution Against Racial and Exploitative Non-Emergencies Act, also known as the CAREN legislation. The name is a nod to a widespread meme using the name "Karen" to describe a specific type of middle-aged white woman who exhibits behaviors that stem from privilege.Some say they support the legislation, but the name is sexist. 691
