Technology company Mona has designed cotton goggles that incorporate a wearer's smartphone to function as a virtual reality headset (+ slideshow).

Much like in Google Cardboard, Mask incorporates two curved lenses that distort a smartphone's display so it covers the user's field of view and makes the image appear life size.
There is a slot for an iPhone to be placed behind the lenses, and the cotton visor is secured in position over the eyes using magnetic fastenings on an adjustable headband.

Fire-hardened biconvex glass lenses at the front of the visor turn the cotton wrap into what Mona describes as a "a 21st-century stereoscope" ? a reference to the Victorian-era device for viewing left-eye and right-eye views of the same scene as a single three-dimensional image. Mona's Mask is machine washable, and the company plans to collaborate with designers on alternative printed fabrics.

"Mask is the culmination of a year of development and refinement," said the company, which is owned by product research and development studio Planeta.
