Access to eye care is taken for granted in the West, but for over 2.5 billion people living in smaller communities in developing countries, little help is available. ClickCheck is an intuitive device for self-diagnosing eyesight. With a production cost of $5, it is cost effective for NGOs to distribute in developing countries. ClickCheck was designed for the social and cultural environment it aims to aid. It is passed from person to person without the need for a professional. The ultra-simplicity and low cost of this solution has made it a success where other vision screening apps or kits have met barriers to entry.
