Eyejusters are a revolutionary new way of helping the world see, but they're based on very successful projects, fieldwork, studies and trials already done with earlier designs of self-adjustable glasses from other groups. We're building on all this work with a next-generation product that everyone can wear.

Self-refraction is the method where an individual adjusts lenses to suit their own eyes, and is the principle that underpins Eyejusters.

Self-refraction has been validated by a number of independent peer-reviewed studies from leading institutions1,2,3, and extensive studies of fieldwork performed in Ghana, Nepal, Malawi, Nicaragua, China and South Africa. It is reliable and effective for over 12s, with a recent independent World Bank-funded international clinical study4,5 validating its use for over 12s.

In use, self-refraction has been found to be as accurate as other field refraction methods, such as auto-refraction, and approaches the quality of a field refractionist performing subjective refraction, the gold standard of refractive eyecare.

Add to your projects
Almost 40,000 self-adjustable glasses are already out in the world, providing clear vision to their owners. Many different organisations have used them successfully in a diverse set of locations and circumstances. Countless smaller organisations have distributed self-adjustable glasses thanks to Global Vision 2020, a US-based non-profit that provides fundraising and training assistance to smaller organisations working in the developing world.
