Portable CCTVs for magnifying menus, prescription bottle labels, etc. still cost around $1,000, out of reach for many folks. Eye Glasses, a $3 iPhone app performs basically the same function by taking the camera feed and bumping it up as much as 8 times magnification.
Eye Glasses is for the visually impaired, whether aging with failing vision or plain short sighted, squinting spectacle-wearers. Hold the iPhone in front of some hard to read text and the app takes the camera’s feed and makes it bigger: up to eight times bigger! It works with any iPhone, but the close-focusing 3GS will give the best results.
