My eyeglasses are broken, and I want them fixed.

I vividly remember the morning I woke up, and could no longer read.

Everything was blurry, and no matter how much I blinked away the night, I still could not read.  I could see things further off, and if I moved my phone well back past my normal reading distance, I could still just about focus.

Eventually my eyes could focus as normal, and I put the experience down to tiredness.  But soon the blurriness came back, and didn't leave.  I was being abruptly welcomed into late middle age.  I needed reading glasses.

I picked up a pair of cheap glasses from the local supermarket, and miracle of miracles, I could read again.  Everything was fine and crisp, even when I used the smallest font on the kindle app.

There was, however, still an issue.  When I was wearing my reading glasses, and I was looking at something that wasn't a book, that was further away, say a person's face, or a stop sign, everything was blurry.  I had to take my glasses off to see beyond the page in front of me.

So, in this age of miniaturized sensors, 3D printers, new material science, why can I not buy a pair of glasses that sense how far away objects are that the glasses are pointing at, and physically deform the lenses appropriately to bring items into focus for the wearer

For me the lenses would become clear glass when looking at something in the distance, and would deform to +0.5 reading glasses when looking at a page in front of me.

There have been similar attempts in the past, but as technology advances, sensors become smaller and motors become miniaturized I think its time to look once again at eye-glasses.  The way they work now is broken.  If Google invested a fraction of the money they have in Google Glass, then I'm convinced they could bring these kind of glasses to the world, benefitting hundreds of millions, And just perhaps, by incorporating Glass-like functionality along for the ride, they could bring Glass to the masses.
