Wearable devices are one of the hottest consumer product categories this year, and eyewear is emerging as an important vehicle for this exciting new technology. High-tech specs and eyewear-like products are turning up everywhere, from city streets to ski slopes. Although most wearers are young, tech-savvy early adopters, the market for these devices is growing steadily, according to industry observers. The upcoming release of Google’s highly promoted Glass is expected to galvanize consumer interest in this emerging market.

Wearable devices in a variety of eyewear form factors are currently available, including smart glasses with screens that let you view data and images, sunglasses that can shoot high definition video and upload it to your favorite social network site, and ski goggles with GPS systems and speedometers. Although these products are mostly being sold online or through consumer electronics or sporting goods stores, some are finding their way into optical dispensaries.

Whether eyecare professionals are selling high-tech specs or simply advising patients on their use, it’s clear they need to familiarize themselves with this new product category soon. The following roundup offers an overview of the features and benefits of some of the latest products.

GOOGLE GLASS
Google recently revealed the technical details of Glass, its soon to be released wearable computer. According to the company’s website, the high-tech specs will feature a high resolution display that is the equivalent of a 25-inch high-definition screen viewed from 8 feet away. A built-in camera will be capable of capturing 5-megapixel images and video at a resolution of 720p and will feature 12 GB of usable memory, synced with Google cloud storage for 16 GB of storage. Audio will be delivered via a bone conduction transducer, Google says.

Glass will also have Wi-Fi connectivity and can communicate with any Bluetooth-capable phone. A companion app, MyGlass, requires Android 4.0.3 (Ice Cream Sandwich) or higher. MyGlass enables GPS and SMS messaging.

Glass will be powered by a battery that will carry a charge for one full day of typical use, although Google noted that some features, like Hangouts and video recording, are more battery intensive. A Micro USB cable and charger are included.

Glass will also have adjustable nosepads and a durable frame that fits any face, according to Google. Extra nosepads in two sizes will be included with each pair of Glass.


EPIPHANY EYEWEAR

If you’re ready to try a pair of smart specs but don’t want to look like a cyborg, check out Epiphany Eyewear. Vergence Labs, a California-based start-up, created Epiphany Eyewear and is introducing a line of stylish specs that feature a thick, black frame made of “shape-memory” nylon, spring hinges and polarized, UV-blocking lenses. They were designed by David Meisenholder, whose portfolio includes Lady Gaga’s GL-20 Polaroid video glasses.

Epiphany Eyewear offers HD video recording with audio, which is controlled by a tactile “on” button on the right temple and HD live streaming through a compatible tablet to YouGen.TV and Facebook. The glasses are powered by a lithium ion battery that can be recharged over USB after one to two hours of video recording, which in normal use of recording short video snippets means about two days of normal use.

The frames, currently available in black only, are equipped with a multiple lens stack with a multilayer AR coating, including a plano front lens that is impact resistant and a 2.00 base lens in the back that can take prescriptions from -2.00D to +2.00. Sandwiched between them is a flat, electrochromic lens that is activated by a small switch at the front of the frame. The speed of activation, from lightly tinted to dark gray, is one millisecond.

Although the current version of the lens can only flip from light to dark and back again, future versions will have the ability for the wearer to adjust the degree of tint they want using an app that controls the voltage. Future versions of Epiphany Eyewear will also have Internet connectivity.

Currently, Epiphany glasses are only available from the company’s website. Prices vary according to how much video storage the buyer wants. Eight GB storage costs $299; 16 GB costs $399 and 32 GB costs $499.
