I've worn glasses since my early teens, went with contacts for several years in my late twenties and somehow I just stopped and went back to glasses. Now I have a defective left eye (from an injury) that is always dilated so I would need to have sunglasses available all the time, even on normal days. So I just have transition lenses that get dark whenever it is light and don't have to think about putting sunglasses on and off which I actually found a pain when I had contacts.

It's my hope that one day we'll all wear glasses - with enhanced imaging features like zoom and night vision, plus overlay of our mobile device screen as needed.

One thing you missed as a huge pain with glasses - so expensive. They are, like women's shoes, one of those ridiculously overpriced items that should probably cost under $100 for the materials and labor involved and yet you can easily end up paying $500 or even $1000 these days.
