And of course, there is a highly elaborate fashion glasses industry amounting to at least $2 billion in sales.

You have hit on it.

Glasses exist in these two worlds, a medical world where people like myself need them to survive.

And growing up without a lot of money, I was forced to just take what I could get at the least possible cost.

Price and the most important thing about them was their durability.

Today, people have such an array of frames to choose from online, although those don't come with the necessary adjustments you get from your neighborhood optician.

And they tend to be an object of consumption.

And yes, they've come out of their shell.

But what about those of us that still need them to see?

And that is huge numbers of people.

tens and hundreds of millions of people in this country alone that aren't looking at them as an accessory like a tie or a barrette, but instead depend on them for their survival.

I think we need to respect that and accept that and accept that glasses will always form different

perform different functions.

Now, looking ahead, what will we wear in the future?

Well, it looks like it will be smart glasses, the first device which will be likely worn as a wearable computer for most people.

And this field is surging.

It's surging so fast, in fact, that we haven't considered one of the most important things about this new technology.

Yes, they'll let us see, but like Google Glass, they'll also let us take pictures and record sound.

from everything we see as we walk by the street, as we enter someone's home, and then stream those images and sounds to a brother, your mother, friends, the police,

So before smart glasses become everywhere and they're doubling in sales each calendar year, I think society is going to have to step up and figure out how we want to protect our privacy.
