The Blue Light Emanating From Your Smartphone Could Ruin Your Eyes

We already know that the blue light from our devices is a major contributor to insomnia. Now, a new study published in the journal Scientific Reports suggests that our ubiquitous screens pose an even more insidious threat. As Business Insider reports, looking at blue light all day can speed up the process that causes blindness.

For the study, researchers from the University of Toledo shined blue light—the same kind that emanates from smartphones, laptops, and tablets—directly onto eye cells. They found that the light transformed retinal molecules in the eye's photoreceptors into molecules that were toxic to the cells around them. The new, mutated retinal dissolved the membranes of nearby photoreceptor cells, ultimately killing them. In other words: Blue light can cause serious damage to the eyes.

Macular degeneration is what happens when photoreceptor cells in the eyes break down, as was the case in the researchers' blue light experiment. Unlike other some cells, photoreceptor cells in the retina can't regenerate, so if enough of them die, it can lead to permanent vision impairment or even blindness.

This process happens naturally to some people as they age, but blue light adds an unnatural element to the equation. If you spend enough time with your eyes locked to a screen, the quality of your vision could degrade much faster than it would otherwise.

The easiest way to avoid this outcome is to look at your phone less, which is easier said than done. A more realistic resolution to make is to avoid scrolling through apps or opening your computer in the dark.

Game of Thrones Star Sophie Turner Opened Up About Her Struggles With Depression

Playing one of the main characters on the most popular show currently on television isn't always as glamorous as it seems. Sometimes, the pressures of fame can be too much. Sophie Turner realized this while playing Sansa Stark on Game of Thrones, and has recently revealed how being in the public eye took a toll on her mental health.

Turner took on the role of Sansa Stark in 2011, when she was just a teenager, and she quickly became a household name. Now, at 23, she's come forward to Dr. Phil on his podcast Phil in the Blanks to explain how negative comments on social media affected her self-image and mental health.

"I would just believe it. I would say, ‘Yeah, I am spotty. I am fat. I am a bad actress.' I would just believe it," Turned explained. "I would get [the costume department] to tighten my corset a lot. I just got very, very self-conscious."

Later on, these feelings led to major depression. Turner developed a sense of isolation after she realized that all of her friends and family were going off to colleege while she was pursuing a sometimes-lonely acting career.

"I had no motivation to do anything or go out. Even with my best friends, I wouldn't want to see them, I wouldn't want to go out and eat with them," Turner explained. "I just would cry and cry and cry over just getting changed and putting on clothes and be like, 'I can't do this. I can't go outside. I have nothing that I want to do.'"

The feelings of depression stayed with Turner for most of the time she was filming Game of Thrones, and it's a battle she's still fighting. "I've suffered with my depression for five or six years now. The biggest challenge for me is getting out of bed and getting out of the house. Learning to love yourself is the biggest challenge," she continued.

The actress shared that she goes to a therapist and takes medication for her depression—two things that have helped her feel better.

Between Game of Thrones ending and planning her wedding to fiancé Joe Jonas, Turner may not have the time to take on many new acting roles in the near future. However, we'll continue to see her as Sansa Stark in the final season of Game of Thrones, and as Jean Grey in Dark Phoenix, which hits theaters on June 7.
