As screen time becomes a bigger part of students’ lives, preserving their vision is something to keep an eye on.Dr. Lauren Schneider, an ophthalmologist who has been treating patients in New York and Connecticut for six years warned screen time can cause a number of symptoms, including squinting and eye-crossing.“We do know that prolonged near work can place some children at risk for progressive myopia, which is worsening nearsightedness,” Dr. Schneider said.Doctors say tips on preserving your kids' vision during remote learning include making sure they keep a safe distance from their devices — at least 15 inches away from the screen is recommended — having them take screen breaks every 20 minutes and investing in a blue light blocker, which can be put on devices or glasses.“Some of our data suggests blue light emitted from our electronic devices may potentially be harmful long term to the center of the retina,” said Schneider Sunday.As school districts in the tri-state area continue to reopen this fall with full remote or hybrid learning models that include screen-based instruction, eye protection is another safety measure doctors say parents should have their sights on.“We want to make sure that while our students are hard at work which is going to require a lot of time in front of the computer that we’re avoiding unnecessary eye strain," Schneider said.According to medical experts, the full long term impacts on the eyes from remote learning are still being looked at, regular eye exams are highly recommended.For more tips and resources:www.visiontolearn.orgwww.childrenseyefoundation.orgwww.kidshealth.orgThis story was first reported by Jennifer Bisram at PIX11 in New York City, New York. 1726

As Vietnam veterans grow older, the National Park Service said it has seen an increase in people leaving remains at the Veteran's Memorial Wall in Washington D.C., so it has now put up signs asking people to stop.Nancy Skinner wanted to honor her fiance Ron Looney after he died in 2008. When he died, Skinner had him cremated.Other than Looney's remains, photos were one of the few things she had left of Looney. The snapshots capture the motorcycle trips the couple took around the country, family get-togethers, and even Looney’s time in the Vietnam War.“He was over there five times,” recalled Skinner.Soon after his death, she took some of Looney's ashes and set out on one last adventure with him. “I went ahead and got what I thought would probably be the right amount if you cremated his heart, the right amount size,” said Skinner.She packed the ashes in a wooden box and drove from Mississippi to Washington, D.C., to leave Looney's cremains at the Vietnam Veteran's Memorial Wall.“It was something he so wanted to do, so wanted to be there. I knew that was something he would have wanted,” said Skinner.The National Park Service said Looney’s cremains are one of about 70 that have now been left at the wall over the years.“A lot of Vietnam veterans feel very connected to the memorial. It speaks to them in a way a lot of other places in the country don't,” said Janet Folkerts, a curator with the Park Service. “Cremains are kind of definitely more sensitive and something that needs a higher standard of care than we're really equipped to deal with here,” said Folkerts.The cremains left at the wall are currently brought to a Park Service building and kept in a metal storage cabinet. But Folkerts said the Park Service is looking into new options.“We’re hoping some veterans cemetery could help us with the cremains we already have and we could setup some system in the future,” she said.While Skinner said she understands the Park Service’s concerns, she hinted she would still have found a way to honor Looney’s wishes.“I made it a pretty little box. And I didn't figure anybody would mind. Makes me wonder if I need to go back and pick him up. But his ashes are still gonna stay there. Sorry," Skinne said.  2274

AVENAL, Calif. (AP) — Authorities say an inmate at a central California prison died of complications from the coronavirus Saturday, becoming the state’s 79th person to have a fatal case of COVID-19 while they were incarcerated. The Avenal State Prison inmate died at a hospital. The prisoner’s name was not released. There have been 15,872 confirmed cases of the coronavirus in the state prison system. Advocates say jails and prisons nationwide are prime locations for the virus to spread between inmates and staff. Officials have released hundreds of inmates to decrease jail and prison populations across the country during the pandemic. 648

As the holidays approach, many people are wondering how to safely celebrate. The CDC has urged Americans not to travel for Thanksgiving, and offering guidance for those who still want to go somewhere. Health officials weighed in on whether you need to quarantine before you visit family for the holidays."My own family, we usually have 100 relatives every year at Thanksgiving. Now, clearly, that’s not going to be happening this year. It’s going to be on Zoom for the big family, but I think there are ways that you can celebrate with your smaller family and get together safely, but it's going to take some work and some planning," said Dr. Tanya Altmann, a pediatrician and spokesperson for the American Academy of Pediatrics.Dr. Altmann says there are a number of steps people can take to protect themselves from getting COVID-19 this holiday season. Ideally, everyone would quarantine for two weeks before and after a get-together. Some families may think about switching their kids to remote learning if they are not already doing it."I don’t think its drastic. If you want to get together with elderly grandparents for Thanksgiving, I think keeping your kids home from school for a week and then testing them on day five to seven, assuming everybody is asymptomatic, can make a lot of sense. Again, I would still try to keep them a little distanced from the grandparents," said Dr. Altmann.But what if you can't switch your kids to remote learning? Dr. Altmann says then it won't be a true quarantine, but most schools that are in-person right now are doing everything right."They're masking, they’re distancing, they’re sanitizing and disinfecting, they’re hand washing. So, what we’re seeing is most kids are not catching COVID-19 in the school classroom during the school day, they're catching it at after-school activities, they're catching it on the weekends when they're gathering with friends or their families or doing things that maybe they shouldn’t necessarily be doing," said Dr. Altmann.So, how long should you quarantine last? For medical professionals, a quarantine usually refers to a person who's potentially been exposed but is not showing symptoms. It's a waiting period to help determine infection."I think really the best guidance is to wait that 14-day quarantine period to have some degree of confidence that you’re not going to become infected," said Dr. Beth Thielen, an Assistant Professor of Pediatrics at the University of Minnesota Medical School and an infectious disease physician. Dr. Thielen says, to be extra careful, you could also test yourself seven days into your two-week quarantine."A testing in between without symptoms is somewhat helpful because we also know there are a certain percentage of people who will develop asymptomatic infections and, in particular, this is probably important for children," said Dr. Thielen.However, testing rules and access varies in each state, so it's best to reach out to your local health official or doctor to find out about availability and turnaround times for results."So, I think for some, where now I'm hearing people are waiting days after a test, and so if you're planning to get tested before a trip and it's going to take four to five days to turnaround the test, that could be the entirety of your trip," said Dr. Thielen.Health officials advise erring on the side of caution, especially if you're planning on visiting elderly family members."I think the most important thing is to be really aware of that it's not just your family. 'Oh, we don't want to catch COVID, we might get sick' but that you could spread it to others who are even more vulnerable," said Dr. Altmann.Experts say to take the highest precautions to create the least amount of risk. 3756
