The Lenzcase adds reading glasses to your iPhone

Sometime ago, we learned "iPhone cases that do more than protect your phone," there are iPhone cases that can pay for things, iPhone cases with built-in headphones, even iPhone cases that pack an extra SIM card for when you travel overseas. Oh, and who can forget the iPhone stun-gun case?
Even with options as diverse as those, I'll bet you never saw this coming: Lenzcase is an iPhone case with built-in reading glasses. Or it will be: Currently it's a Kickstarter project seeking $28,000 in funding.
This is exactly what it sounds like: An iPhone case (currently iPhone 6 only, with the possibility of 6 Plus, Samsung Galaxy 6 and other versions down the road) with a set of reading glasses tucked away inside a rear enclosure.

Keep your cheaters tucked away until you need them. Lenzcase

That enclosure adds just over a quarter inch of extra depth to your iPhone, so the entire package is not overly bulky. Each Lenzcase comes with four sets of lenses -- +2.0, +2.5, +3.0 and +3.5 -- though obviously only one fits inside the case at a time.
When you need it, you just push in slightly and the lenses pop out via a spring-loading mechanism.
The idea here is to free you from having to carry around a bulky eyeglass case, or from wearing "cheaters" on a chain around your neck all the time. If you're someone who occasionally reaches for a pair of specs to help make out small print, this might be a handy accessory.
I say "might be" because there's one key limitation: the lenses don't have arms, so you can't leave them on your face -- you have to hold them up to your eyes for as long as you need to read.
Assuming that's OK with you, early backers can score a Lenzcase for $28 shipped, with delivery expected in December. And if this does sound like a winning idea, you should definitely grab that deal, because the product will retail for $79 (plus shipping) once it goes into production.
