A reference value above which visual acuity is considered normal is called 6/6 vision, the USC equivalent of which is 20/20 vision: At 6 metres or 20 feet, a human eye with that performance is able to separate contours that are approximately 1.75 mm apart. [9] Vision of 6/12 corresponds to lower performance, while vision of 6/3 to better ...
The chart was designed by Ian Bailey [5] and Jan E. Lovie-Kitchin at the National Vision Research Institute of Australia.

The largest letter on an eye chart often represents an acuity of 6/60 (20/200), the value that is considered "legally blind" in the US. Many individuals with high myopia cannot read the large E without glasses, but can read the 6/6 (20/20) line or 6/4.5 (20/15) line with glasses. By contrast, legally blind individuals have a visual acuity of 6/ ...
cognitive biases to promote better behaviors. This approach has been advocated by scholars in behavioral and health economics as a promising method by which to address non-optimal consumer choices, including financial and health related behaviors (Rebecca K. Ratner et al. 2008, Kelli K. Garcia 2007, Peter Kooreman and Henriette Prast 2007).
In such a socialist society based on economic planning, the primary function of the state apparatus changes from one of political rule over people (via the creation and enforcement of laws) into a technical administration of production, distribution and organization; that is, the state would become a coordinating economic entity rather than a ...
