Well stated - there's nothing more annoying than heading outside to get the mail in the morning, and having to wait 60 seconds for the eye glasses to clear up so you can see where you're walking when you come back into your house. Or, if you store your sunglasses in your cold car, the moment you put them on to back out of the driveway, instant fog. It takes a good 30-60 seconds for the heat from your head to clear up the lenses when you're wearing contacts and want to wear sunglasses. The application is long overdue in my opinion.
Likely, only those with expendable income might be able to afford these. Electronics comes at a cost as we all know. ; )
Indeed, the invention might have its use case. In cold climates, the heating element in the lens frame (crucially important components not shown in the excerpt) will supposedly keep the glasses from fogging up.
My issue is that item 28. What's it for? What signal is the "amplifier" amplifying? Presumably the cell 24 is providing the bias voltage for the op-amp, but to what end? Anyone?
If you wear glasses as I do, there are times when having heated eyewear would indeed be useful. In winter time, your classes can get very cold and instantly fog when they encounter warm moist air. Depending upon what you are doing, this could introduce a element of confusion that could have serious consequences.
So I would not laugh too hard at this one, it actually addresses a need, albeit a low probability one.
Just my opinion.
I've always thought of my ears as heat sinks. Even in moderately cool temperatures, they can easily get painfully cold. I suspect they are thermally connected to specific areas of my brain and over cool those areas.
Given that, I would welcome an ear heater. Perhaps they could even add some improvements such as a heat pipe people like me can stick in their ear.
On the other hand, I don't wear glasses, so never mind.
