Beyond the Father's Day card

I was at the store the other day hunting for a Fathers Day card.

I kept coming up short. According to Hallmark and the rest of the greeting card contingent, dads come in only four categories: grill masters, sports fanatics, golf aficionados or anglers.

The problem is, my dad doesnt fit into any of these categories.

In fact, many of the father and husband figures in my life cant be boxed into such limited stereotypes. Sure, they might watch the occasional football game, but they cant be constrained by fishing poles and grilling tools.

Looking at the cards, one would think we are still firmly in the 1950s, where the distant, authoritative father figure is defined by what he does instead of who he is.

The fathers of today, the ones I admire, are thoughtful, sensitive and good communicators. They are on the ground, in the trenches (dispelling another Fathers Day card trope, the one that begins with Dad, I know we never talked much.)

They are on the floor changing diapers. Theyve got a toddler on their hip in the foyer at church. They have spaghetti up to their elbows because they are parked in front of that high chair.

They jump on the trampoline with the kids. They sit by their son into the wee hours, coaching him through long division.

When I look at the dads of today, I have great hope for the future. They build relationships with their children. They are open about everything from finances to intimacy. They present themselves to their children not as untouchable gods, but flawed individuals acting upon grace, learning precept upon precept.

I cant help but think that our sons and daughters are going to be well-equipped and better adjusted because of these father figures. Dads of today dont just swoop in right before the closing credits to dispense sage advice. They dont hide behind a newspaper or a lawnmower.

The dads I know dont get stuck in a dreaded desk job, punching the clock. An astounding number of them take daring leaps into the unknown. They write books, start businesses, invent a new way of making ice cream. They create things with software or with 3-D printers. They go back to school in their 40s, or they drop down to part time so their spouses can pursue their dreams.

In fact, if I were to rewrite the Fathers Day card, it wouldnt be a card at all. A card is too one-dimensional, too stiff. And perhaps thats the problem. I imagine the good fathers, the ones worth emulating, havent changed that much in the last 50 years. Theyve simply given themselves permission to break out of the stereotype affixed by TV shows and beer commercials.

In my mind, the perfect Fathers Day card would have to be a 3-D model, painstakingly printed over years of coaching and mentoring. It would be exactly life-size and entirely indispensable.

Every year, I grow more grateful for the role of fathers, grandfathers, uncles, brothers and strong male role models. We need more of them. And the ones we see who are lugging a diaper bag or throwing themselves in the middle of the action need to be encouraged and celebrated.

Happy Fathers Day to all the good dads of the world.
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.
