The start of a new school year can be a tricky time for budget-conscious consumers.

School supplies may not be as costly as Christmas presents, but the price tags on cool new outfits or backpacks, as well as last-minute family adventures, can quickly add up. Extra purchases in August hurt bank accounts already hit hard by summer splurges, according to financial experts.

"Many of us give ourselves a little more latitude (financially and personally) during summer," U.S. News & World Report notes. "Back-to-school season is a good opportunity (even if you're not a parent or student) to revisit your finances and get on track for the rest of the year."

This month, families should check in with financial goals, the article reports. Parents of school-aged children can adjust budgets to reflect that kids will now need to pay for a lunch at school or pack a sandwich and also account for the fees associated with sports or other school activities.

If there is still a lot of shopping to do before school starts, parents can guide their young students to the stores offering the best deals.

CNN Money published a list of the best back-to-school deals on technology this week, and a second article from U.S. News & World Report shared five smartphone apps that offer great deals on school supplies.

The theme of the season should be keeping impulse buying in check, a piece of advice more and more Americans seem able to follow, as credit counselors told NPR recently. The article highlighted how people's spending habits, including their approach to school supplies, have changed since the Great Recession, celebrating those who are careful with their credit cards.

"According to the National Federation for Credit Counseling, only about one household in three now carries credit-card debt over from month to month. That's a drop from 2009, the peak of the recession, when 44 percent of households carried credit card debt," NPR reported.
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.
