Need Bluelight Glasses?

Do I need blue light glasses? How do I separate fatigue from facts?

This is a stamdard chart showing the electromagnetic spectrum wavelength. Humans perceive visible light as colors because of these different wavelengths.
Will glasses block the blue light?

Dear Ms. Smartphone: I saw my gorgeous daughter-in-law for the first time since the lockdown, and was surprised she now wore glasses. When I asked, it turns out these are not prescription glasses, just a frame with special lenses to filter out “blue light”  from the computer screen. This is all new to me.  Is it useful and should an older person, like me, be filtering the blue light too? Esther, Corinthian Island

Dear Esther: Chances are that your daughter-in-law spends a lot of time on the computer now that the office is closed and business is conducted remotely. Until the lockdown, office workers could break-up their screen time with in-person meetings, voice phone calls, and a beverage break. Now, it is straining on the eyes (and well being) to focus on a single screen, or multiple ones, for eight to ten hours a day. It’s  hard to sort out the effects of general eye fatigue from the specific effects of blue light.

Citing from a Harvard Health report, blue light is visible light with a wave length between 400 and 450 nanometers. LED displays and specifically the backlight displays on smartphones, tablets, and laptop computers look “white” but they are emitting blue light. These high wave lengths have more energy per photon of light than other colors so at high enough doses, they could cause damage when absorbed by various cells in our body.

As more computer users worry about their eyes and clamor to get protective eye gear, others claim that this is just aggressive marketing and up-selling. Many medical experts refute the claims. I encourage you to read up more and try to sort it out.

Smartphone Display

That said, why not check-out what’s baked into your own smartphone? There has been a different, but related concern: blue light from phones interferes with the circadian clock, that is adaption between night and day.

On your iphone or ipad filter out blue light by going to the Display and Brightness screen, and then tapping the Night Shift setting. On an Android look in Settings>Display>Blue Light filter.  To further protect, consider getting a special screen protector for your computer and smartphone – it will block light in the 380-500 nanometer range throughout the day (not just night). 

Age Spectrum…Light Spectrum

I have an interesting anecdote to pass on. When I last visited my ophthalmologist in 2019, the clinician told me she was seeing more young children with vision problems. She encourage me, a.k.a. Dear Smartphone,  to tell parents to withhold Ipads and phones from kids.  BTW,  blue light effects are not confined to young people and office workers. It is thought that it might hasten macular degeneration in older folks. Note that for every research study pointing in one direction, there seems to be refutable evidence in the other. But, if you liked the fit and look of your daughter-in-law’s glasses, why not try a second pair?


Selfies for Good?

The Posted Video Kept Getting Shorter….but Funnier!!

This is a screenshot of words, translated from Italian to English by Google. The writer is saying a YouTube video of a tourist falling int he canal is a fake.
Is this fake news? A public comment posted on YouTube

Dear Ms. Smartphone: This week you posted on your Instagram a YouTube video on selfies that went viral in November (2019). It’s about a man with a selfie stick that falls in the water.  It was funny, but honestly, what is the difference between your own repost and say an edited short on Quibi TV? Russ, San Francisco.

Dear Russ:  Correct, I seldom post videos or watch Quibi because they require that I hand over my most precious resources: my time, my attention, and possibly, my privacy. But, the post you mention is more content on selfie-sticks and our isolated future. In 2014, the sales of self-sticks peaked and my prediction is that they will resurge, as we reach out to strangers less and less.

The video you mentioned shows an unidentified man in a Santa Hat obliviously stepping into a Venice, (Italy) canal during the “Alta Aqua,” or high water. He is looking at his phone screen, steps off the sidewalk, and plunges under. In this four second video, only the selfie stick and his phone remain above the water line.

EEK! Which Version Is THE Real?

I am happy to tell you that the plunge was not fatal and selfie-man emerged a micro-second later. But, and here’s the point, I know this because I found an earlier version of the video that was 17 seconds long. In a 26 second version of the video, the Santa hatted man pops right back up, and says a few words to a friend, seemingly the one filming him. This version is the first I can find online, it was posted about a week earlier, and it is from the UK Daily Mail.

The shorter version you saw, just four seconds long, also got posted on Facebook and it gets all the laughs. There was a lot of back discussion on Reddit of whether the whole video was staged (after all, someone is assiduously shooting selfie man) and in the public comments there is a small remark, in Italian, that the video is Chioggiotti stunt (see image). I also tried to contact the person who posted the shortened version of the video on Reddit, but no surprise, he did not message back. I want to know who edited the video…and why!

Fake News or Amateurs?

Maybe we only have attention spans of four second now, particularly on Instagram or TikTok. The problem is that the fuller story has been truncated and it’s easy for the naive viewer to reach the wrong conclusions. Why is this relevant? Fake news doesn’t have to originate in made-up events, it just has to be real events that lead us, often because of what is left unsaid, to misinterpretation or wrong conclusions. 

Seeing “Aqua Alta” from someone’s homemade video is, in many ways, as powerful as the news clip from a professional network TV crew (I personally like the news shots of suitcases floating like gondolas down the Grand Canal). But, when we are in the field as amateur journalists, we need to be there with a sense of responsibility. When we post: who is taking the picture, why are they telling the story, and is this the full story or one with edits?

We are all amateur journalists as the selfie-stick makes a rebound. I’m not putting down funny, I’m just saying that we also need to bake in reliability and trust as we edit and post our experiences in our brave new post Covid world.

Zoom & Telework make me sad?

We spend the day in on-line meetings and the evenings in on-line meetups. Does that make us feel connected with each other?

Dear Ms. Smartphone: I am spending a lot of time with my co-workers on Zoom and other video platforms; then I do online yoga in the evenings. When I am working I find that I am really distracted by the backdrops and feel like I am peering into people’s personal lives. Do I say something? When I do yoga, I feel alone and I miss the studio. At the end of the day I am really tired even though I have not gone out ? Is it like this for others during the quarantine? Valerie, Sausalito

Dear Valerie: These are indeed unusual times and I hope that you have a support network of friends and family. It’s good to reach out to others. They are probably feeling just like you.

We are all learning new communications etiquette. When we meet in person, say for a business meeting, all parties process the visual cues in micro-seconds… that’s probably why in-person meetings start off slowly with small talk. When you get invited to the boss’s office for the first time or have a job interview with a higher-up, subconsciously process data about this new space. You observe the decorations, diplomas and favorite photos, and spatial layout, as you also (try to) maintain the thread of conversation.

Kinesics

So, your question about backgrounds and micro-cues is relevant. Ray Birdwhistell, whom I studied with at Penn, proposed that kinesics, the study of human body motion, is culturally specific, and deeply invisible. There is a maxim frequently attributed to him that 30 to 40 percent of communications is verbal and 60 to 70 percent is paralinguistic (body language). I honestly never heard him say this. But, he did believe that all movement conveyed meaning. He would have a heyday today processing all the gestures, twitches, and blinks on telework channels.

Perhaps that is what makes Zoom-like video so tiring. We are trying to follow the the cues, but can’t quite grasp the subtlety: the speaker’s lips, eyebrows raise and lower, eye squint, flick of the hair: kinesics we need to interpret and respond to if we verbally jump in or back off. 

Connection Channels !!

Meanwhile, there is a third channel that Birdwhistell could not anticipate. We also have to process imperfect technology: things like a fuzzy connection, asynchronous dialogue, and poor background lighting. While TV watching brings expectations for professional media, this standard does not happen from home. I know this linked study was done in 2017 to support a video compression pitch…… but it suggests that we use subconscious reactions to judge video.

Does lower quality streaming decrease happiness and focus, and increase negative emotions? And, does better streaming make us happier, as the image suggests? Here is a PhD dissertation ready to be written!

Pink Kitty Backgrounds

During the past week, I found that simplicity works… yoga studios that stream a class with a blank wall and a live instructor keep my focus. That said, instructors who would normally be effective in-person do not necessarily translate well or telegenically into video. 

And, like you I find that meetings or classes with teleworkers can be jarring. Instead of focusing on the conversation, my attention wanders to the pink-kitty pillows and lumberjack shirts (are they really wearing pants?) Even when the background is a non-descriptive doorframe or window, our minds leap to fill in the pattern of the full room.

There’s a reason that business people have discovered backdrops, just like professionals on TV news! So, for practical tips, see this helpful Wall St. Journal article.

Video UNHappy Hours…

Perhaps the ultimate stress is “video happy hour.” It tends to be less happy that it sounds because of the intense time we stare at the screen without being able to look away and wander out. If we were sitting at a bar stool ‘IRL’ we might be nominally engaged with our phone, with the bartender and guests, and reacting, in a subtle way to sounds and motion throughout the establishment.

When we sit at home, it is all so new, and we are learning thee new video protocols together. As the technology matures, and we mature with it, we will, collectively, become more adept at reading on-line kinesics, wandering on and off the screen both mentally and physically, and settling into other peoples’ personal spaces.
