The price of the physical glasses is minor — only $1.88 for a new pair of ready-made spectacles. Most of the costs of delivering them go for labor and travel expenses to, for example, bring a team of optometrists and opticians from Australia to Cambodia.
Using labor costs based on wage rates in Australia, where the research was done, the cost of delivering a pair of ready- made glasses is $11.28 (in U.S. dollars) for lower powers requiring only a visual inspection and $13.23 if the lens power is checked with a focimeter, a tabletop instrument that looks something like a microscope. (These costs do not include an exam to determine the prescription.)
