Researchers at the University of Houston have created an optical lens that can be placed on an inexpensive smartphone to magnify images by a magnitude of 120, all for just 3 cents a lens.

Wei-Chuan Shih, assistant professor of electrical and computer engineering at UH, said the lens can work as a microscope, and the cost and ease of using it — it attaches directly to a smartphone camera lens, without the use of any additional device — make it ideal for use with younger students in the classroom.

It also could have clinical applications, allowing small or isolated clinics to share images with specialists located elsewhere, he said.
