These are the glasses with a built-in video camera that allow you to discreetly record all that you see. The 0.3 megapixel pinhole camera is located in the bridge, providing 320 x 240 high-quality resolution for AVI videos. Up to 2 1/2 hours of videos can be recorded directly onto the built-in 2 GB memory. The left temple's frame houses a slot that accommodates a microSD card for additional memory storage. Videos can be copied to a computer running Windows XP/Vista using the built-in USB port and included cable. You can also download MP3s to the glasses and listen to them using the included earbuds. The built-in rechargeable battery provides up to two hours of recording from a two-hour charge using the included AC adapter. The plastic lenses use UV-400 coatings. (12 oz.)
