Melatonin Busting Glasses

Yesterday morning I read about Amazon's pricing mistake, where folks were ordering thousands of dollars worth of photography equipment for about 90 dollars per item. I checked the UK's Amazon site but the prime day was over, but something caught my eye. Scrolling down, there was a man wearing a futuristic looking band around his brow, emitting blue lights. This was Amazon Launchpad. But, as I searched for the item within Amazon Launchpad, I couldn't find it.

I decided to enlist the help of Yugesh, the most excitable Amazon representative I've ever spoken with. He decided to do some research with me, and discovered the device was a pair of Light Therapy Glasses. Not very exciting, I thought, and especially not for £260+.

As I looked into it, I discovered that blue light, especially around 460nm, stimulates intrinsically photosensitive retinal ganglion cells (ipRGCs) within our eyes, which suppress melatonin production, leading to enhanced wakefulness and reduced tiredness. It makes sense really. They say not to use your phone an hour before bed. To use the feature that reduces blue light, what I think of as the Lux effect.

But what if we want to feel awake?

So I decided to design and build some melatonin busting glasses, for a fraction of the price. I purchased some Lithium coin batteries, some disposable glasses, and dug out my electronics chest to do some inventing. One of the first things I had to do was construct some blue LEDs that wouldn't blind me. I needed diffused light but all I had was some ultrabright LEDs. So, I took some plastic from bags of zener diodes I had bought from CPC years and years ago, stretched it over the LEDs, and then secured it with some heatshrink tubing.

custom LEDs

Great, then, I had to construct the power cells. I used two sets of 2 x 3.2v Lithium coin batteries, which I sealed with hot glue and electrical tape. I wasn't too keen on heating the batteries in order to solder the leads onto them directly, what with being in an apartment and not a lab. I did try, but it was a half-attempt, I already knew the solder wouldn't stick.

After this, I mounted some LED mounts onto the glasses, a small switch, the power cells at each side, so the weight is distributed, and then went ahead and wired it up. The result? Melatonin Busting Glasses. A little bit rough around the edges but I always think of it like the poetic-license equivalent of engineering. Prototypic-license.

Finished prototype

Four gloriously diffused but bright blue LEDs shining into the periphery of your eyesight.

Melatonin-be-gone

Disclaimer: I have about as much proof that these work as the producers of these types of glasses on Amazon have. I've now given these prototypes to a test subject who will try them out for a while and report back any noted effects. Please be careful shining lights into your eyes.

Every OS: makes the blue color filter to make users feel comfortable
Dev.to users: creates glasses with 4 blue LEDs shining into their eyes

I love this. I actually don't care if they work or not, but I think the thought and concept behind them is the important part.
I'd absolutely sort them into a contemporary media art category and sign up for more of that :)

Don't keep us waiting.... What's the verdict???

Inconclusive. Never heard back from the test subject. Both test subject and prototype assumed lost.

Still makes for an interesting story, thanks for sharing

I'm not sure if I wrote this in the blog post but the best part was because the lights were shone into your periphery, they didn't affect your vision, so you could continue working or going about your business. I did get strange looks sometimes though, especially when answering the door to the postman.
