From your smartphone to your TV, computer or tablet, many of us pretty much stare at screens most of the day. This can put a strain on our eyes, which is why some people are turning to blue light filtering glasses. "I get people in here every day saying that their eyes get really sore, they burn or get really dry by the end of the day," said ophthalmologist Lauran Zimski. "When people sit at a computer, they blink about half the amount of times they would normally blink."You can find the blue light glasses at eyeglass counters, online and at big box stores. They can cost anywhere from up to 0. "So, blue is a particular wavelength of light that has been shown to basically keep you awake during the day," said Zimski. Zimski says there’s research that supports the theory that the glasses help people sleep."There's a lot of good research that shows if you wear blue blocking glasses before bedtime when you're looking at a digital device, you will fall asleep easier," said Zimski.But, if you're sitting in an office all day, Zimski says "there’s no real evidence that it helps with eye strain during the day staring at a computer."So, what does that mean for those addicted to their devices?"I certainly do have patients that feel like they do help with eye strain at the computer so you can certainly try them, but they may or may not make a difference," said Zimski. 1396

For generations, Dave Walton's family has owned a farm in Wilton, Iowa.“We bought this farm in 1901 so I’m fourth generation of this farm," Walton says. “We grow soybeans, corn, alfalfa; pasture beef, cattle, sheep."Walton knows the impact of the trade war firsthand. “Soybeans have been hit hardest, they were one of the first products to get tariffs," he says. The farmer says tariffs have brought a level of uncertainty soybean farmers haven't seen in a long time. “China is our largest export buyer overseas," Walton says. "Our biggest buyer of soybeans essentially has been out of the market for about a year and a half now. That dropped our price almost a bushel.”The price change for many Iowans like Walton has left its mark.“We’ve really tightened the belt, we had to look at every expenditure. We haven’t really purchased any equipment, haven’t replaced any equipment. We’ve done the repair work ourselves," he says. "The family living budget is down to the bone so we’ve really had to tighten the belt to get through this.”He says waiting for a trade deal between the U.S. and China has been an emotional roller coaster. "You know, you hear they get together and get some positive news out of D.C., or whoever they’re negotiating, and you have a little bit of hope, and a week later it blows up with a tweet sometimes or the Chinese say ‘no, we’re not going to honor that deal,’ " he says.It's a waiting game he says can't go on forever. "The clock’s been ticking for a while,” Walton says. “We’ve made adjustments and the market starting to come back. If we can stay at this level, we could probably ride it out for a little while. But I would say another year and a half, two years … if we don’t have a deal, things are going to get pretty grim.” 1774
