Ah yes, glasses and hearing aids... know them both well. I've had Zeiss progressive lenses for thirty years, and can't imagine life without them. Yes, I have only two pairs because of the cost, but each pair lasts me a good five years. They are around $1k per pair, have been for years. So I figure $200 per pair per year isn't a bad deal since I need my glasses to find my glasses and do a great deal of fine work and reading.
My hearing aids are Phonak, fully bluetooth and usb charged. They're like Derek Flint's cigarette lighter, do 72 things and let me hear: I am completely wired into my android phone, for telephone, audiobooks, television, computer. The Phonaks were $6600 for a complete warranty, all regular service included at my ENT office, for three years. Paying $2200 per year to hear and be fully engaged in my world has seemed well worth it to me. And yes, as Provincial said, it has Bose audio sensitivity and noise supression all built in. I find the android app to be useless and the suppression of crowd noise to not work at all, but I'm not complaining.
Provincial -- the tv link is phenonemal. In fact, to watch tv with my wife I have to remove my left hearing aid to be able to hear her and the tv, because nothing pisses her off more than my not hearing her talk. It's a little (2"square) that sits in front of my screen, direct bluetooth via miniUSB.
On both hearing and eyeglasses, I could have done both with major price savings, accompanied by equally major functionality compromises, decided I needed both to maintain the quality and speed of my functionality at 70, since both are compromised daily by what seems to be rapidly eroding but probably normal strength, flexibiity and mobility.
