What's to blame for low-income divorce rates?

Is it too much to ask for an ideal marriage?

A 2014 study by the Pew Research Center found when it comes to finding the ideal mate, women want a man with a steady job. Just under 80 percent of never-married women said "finding someone with a steady job would be very important."

The study also found 70 percent of women also want to find someone who has similar ideas about having and raising children.

And what are those ideas? According to a 2007 poll, also conducted by the Pew Research Center, couples want a more even distribution of responsibilities.

A more equal division of domestic life, according to the poll, has become one of the defining features of a good marriage. It outranks having an adequate income, sharing religious beliefs, or even having children.

This yearning for a more equal division of responsibilities, and by extension a more equal partnership in general, might be one of the reasons why lower-income families haven't seen declining divorce rates like the national average.

"What we have is historically high expectations for what young people call a 50-50 marriage," Bill Doherty, a professor of family social science at the University of Minnesota, told The Washington Post's Darlena Cunha.

"People are looking for a high-intimacy, high-income marriage where both partners contribute, regardless of income bracket," he continued. "Unless you have a good economic base and a certain level of personal maturity, it can be very hard."

According to Cunha, this trend has hit lower-income families the hardest. Couples who struggle economically are having a harder time managing these ideal marriages, and it's leading to divorce.

Why the poor have higher divorce rates than the rich and the middle class is something researchers have been trying to comprehend for years, especially because studies show that the poor value marriage just as much as the other economic demographics.

"A lot of government policy is based on the assumption that low-income people hold less traditional views about marriage," researcher Benjamin Karney, a UCLA professor of psychology, said in a press release in 2012.

"However, the different income groups do not hold dramatically different views about marriage and divorce and when the views are different, they are different in the opposite direction from what is commonly assumed."

According to The New York Times' Stephanie Coontz, high divorce rates among lower-income families represent a fascinating paradox.

"Since the 1970s, families have become more egalitarian in their internal relationships. But inequality among families has soared," she wrote in 2014. "Women have become more secure as their real wages and legal rights have increased. But families have become more insecure as their income and job instability have worsened."

So just as families have grown more equal, "rising inequality has changed family dynamics for all socioeconomic groups."

According to Cunha, women have rebounded from the recession better than men, and they are also graduating from college at higher rates. Therefore, women are becoming increasingly impatient with the economic stagnation of their male counterparts.

"I realized that since I was the only reliable person in the family making money," one divorced woman told Cunha, "there wasn't much reason to hold onto that marriage."
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
