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 the polar ice caps retreat, polar bears could struggle to survive by the end of this century, a number of university researchers wrote in a study published in the Nature Climate Change journal.The study looked at a number of sub-species of polar bears who live in the arctic and how they have adapted to reduced sea ice from 1979 to 2016. The group of researchers said that all but a few sub-species of polar bears will be able to reproduce and survive given projected conditions by 2100.Polar bears use sea ice to capture seals for food. When sea ice erodes for the summer, polar bears fast. Although polar bears are capable of fasting for months, there are limits to how long the bears can go without food.The researchers examined energy needs of polar bears, and that the amount of time polar bears would fast would lengthen to a point that makes it too challenging to survive and reproduce.While resting female polar bears can generally fast for longer periods of time, reproducing females, males and cubs all require shorter fasting periods, the research found.“Avoiding continued sea-ice decline requires aggressively mitigating greenhouse gas rise,” the researchers wrote, “and our results explicitly describe the costs to polar bears of avoiding that mitigation.”To illustrate how much sea ice is being lost, NOAA is projecting that the arctic could have ice-free summers by 2042.Scientists have long discussed the possibility that polar bears could become nearly extinct by the end of the century. Beyond reducing carbon emissions, proposals have included relocating cubs to areas of the Arctic expected to retain higher levels of sea ice have been proposed.

AVALON, Calif. (AP) — The nonprofit organization that owns a majority of California’s Santa Catalina Island plans to boost eco-tourism by adding more bison to existing herds, recharging a debate over their environmental impacts. The Los Angeles Times reports the Catalina Island Conservancy says there has not been a bison calf born on the island in seven years and the herd size has dwindled to 100. The conservancy board is working to bring two pregnant bison to the island. A biologist says bison herds stay on isolated patches of grass and adding more animals will not result in more bison sightings by eco-tourists. 628

  

Attendance at San Diego Padres home games is on pace to finish more than 11 percent higher than the turnout for 2018. Through 65 home games, the team has drawn an average 30,200 fans per game. In 2018, the Padres drew an average 26,967 fans to games at Petco Park.The team made a splash in the offseason by signing superstar third baseman Manny Machado to a 0 million contract. Plus, excitement surrounding rookie Fernando Tatis Jr., now injured, has helped to draw fans. The Padres, still below .500, have also won 10 more games at this point in the season than they had at the same time last year. Olivia Millay, a server at Social Tap, which is next to Petco Park, says the increased attendance has helped business. "People are getting a lot more excited," she said. "I feel like last year there was almost more people cheering for the other team that would come here. Now you're seeing a lot more Padres jerseys. You've got Machado, Tatis, ya know?"But the uptick in attendance hasn't helped all business equally. There are still multiple shuttered storefronts near Petco Park, including the site of what used to be Tilted Kilt on 10th Avenue. Alina Ahmed, who owns Cafe de L'Opera, across from Petco Park, said high rents hurt. Plus, she pointed to issues with the area's homeless population that can keep customers away. "In the morning everyday we have to remove transients that are sleeping, along with many other issues," she said. Ahmed said the increased attendance has helped a bit, but can only do so much. 1531

  

At a time when people across the country are calling to defund the police, or outright abolish them, convincing others to make a career in law enforcement could be a tough sell.For Cameron Mosher, however, the decision to put on the badge for a living is an easy one.“For me, it’s always been an urge to serve my community,” he said.Mosher is training to be a deputy sheriff at the Orange County Sheriff’s Regional Training Academy in Southern California.“I want to try to be that positive change in law enforcement to try to help and move forward with this career,” he said.Moving forward and maintaining order as the country deals with a pandemic and social unrest.“I have a brother in St. Louis, Missouri, not too far from Ferguson, and we’ve had some interesting debates over the last five or so years,” said Lt. Joses Walehwa, who is helping train a new group of recruits at the Orange County Sheriff’s Regional Training Academy.Walehwa says his team is preparing the next generation of law enforcement officer for much more than traffic stops and arrests.“As an African American, or really any minority group here in America, has a unique perspective when it comes to just their lived experience growing up,” he said. “I think for me, the biggest impact is bridging the gap. You know, bridging this issue of us versus them.”Walehwa says another huge impact when it comes to recruiting is the economy.“When the economy starts to dip, you see that people start to look for stable jobs,” he said. “Law enforcement and public sector and jobs like ours become a little bit more appealing because people see the stability of the job.”A job where despite a pension and a mean annual wage of more ,600 (Bureau of Labor Statistics), there’s still a major need for more sheriff’s deputies across the country.A recent report from the Police Executive Research Forum shows 36% of respondents said the number of applicants at their agency has “decreased significantly.”For recruits like Mosher, however, working in law enforcement means much more than money. It’s about building trust in his community while also addressing new challenges and raising the standards of law enforcement officers.“We see definitely a lot of people who are not necessarily supportive of law enforcement right now,” he said. “But in the end, that’s totally OK, because we’re here to support everyone. We’re going to protect everyone equally.” 2424
