Is an item that may be part impulse purchase and part kitschy knick-knack worth it? - photo by Sarah Anderson
Between standard summer travel and the upcoming Olympics, there are plenty of opportunities available for consumers to buy a souvenir. But is it something you really need? Should you control or perhaps even eliminate your souvenir spending?

Its nice to have something to remember your trip by. There may even be quite the story attached.

Bram Reusen, for example, wrote for La Paz that while I would never ever spend money on obviously kitschy objects in my day-to-day life, he loves buying souvenirs. One of his stated favorites is a piece of patterned fabric, hand painted by an Australian aboriginal women, on his first solo trip backpacking around the continent.

Despite the story or memory attached to a souvenir, keep in mind that the item is marked up by more than 50 to 60 percent higher than it's true value and its something you wont get much practical use out of, as wisebread.com noted.

Weighing the limited luggage space against the cost of souvenirs (and what that money could have been spent on instead), one contributor to whereverwriter.com said shes given up on buying souvenirs.

When I went on my trip to Italy, Greece and Spain, I spent about $100 just on souvenirs, wrote Amy (no last name given) for whereverwriter.com. Thats insane. Those $100 could have been spent on a memorable experience in Europe, but instead, they were spent on overpriced souvenirs.

Ultimately, the worth of a souvenir may come down to a simple equation of its future sentimental value versus what a traveler is willing to pay, saverocity.com noted.

Having some token to remember this trip by might be worth more than the money itd cost to purchase it, it noted.

If souvenirs are for you, here are a couple of tricks you can use to save money.

The Christian Post suggested drawing up a list before setting out that would address:

  • To whom will you give a souvenir.
  • What kind of item that loved one would like (as opposed to something purchased in haste at the airport that they quickly forget about)
  • What youll specifically budget for souvenirs
Keep the list with you, crossing off names when you buy something, the Post continued.

Or you could get creative with what you consider a souvenir for yourself. For example, a journal to chronicle your experiences can count as a souvenir if you keep a detailed account of what you see and do, globe-trottica.com advised. Shells you pick up on a beach, postcards, stickers, street maps, newspapers, foreign coins and plane tickets could all count as mementos of your travels.
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.
