The role of contact lenses in the development of three-dimensional image technology has been outlined by a writer.
Rick C Hodgin wrote on TG Daily that in order to see images in 3D, each eye has to receive a different view.
He explained that this can only be done, currently, through use of glasses or contact lenses and detailed the two methods used for 3D viewing - polarisation and the faster projecting of alternating pictures, used for 3D monitors and televisions.
In each case, glasses or contact lenses are worn in order that each eye sees only the image it is supposed to and to block out the picture intended for the other.
Recently, it was announced that Disney and Pixar will work together on a number of 3D films over the next four years.
Chief creative officer for Walt Disney and Pixar Animation Studios, John Lasseter, said: "We"re excited to be pushing the boundaries of 3D and computer technology to tell our stories in the best possible way."
