For non-emmetropic subjects, the eye with the lesser spherically equivalent refractiveerror was selected as the test eye. Local changes in eye growth induced by imposed local refractiveerror despite active accommodation. The proband had spherical equivalent of 0.50, right eye and 1.75, left eye; the brother had no refractiveerror. The refractiveerror of each eye was corrected with miniature spectacle lenses that optimized the response of an isolated neuron to a high spatial frequency sine-wave grating. Many people with this amount of normal refractiveerror can manage perfectly well without distance spectacles. From the Hansard archive Example from the Hansard archive.
