Confusion between two or more distinct devices
This article appears to confuse two (or perhaps more) distinct devices that appear to share the same name. In particular this reference shows a device that is clearly very different from the device being used to measure refractive error in rural/developing world populations. The "usage" section of the article relates to the former, not the latter.--Srleffler (talk) 06:11, 29 November 2008 (UTC)
