Abstract

A linear algebraic transform is established that adjusts images to be rendered by a computing device to the human from a default rendering for the baseline normal visual acuity to an adjusted rendering for the deviated visual acuity. Before visually presenting the images to be rendered by the computing device the linear algebraic transform is applied, which results in the adjusted rendering of the images. The images of the adjusted rendering are visually presented after the linear algebraic transform has been applied. The human, with myopia, hyperopia, or both, is able to perceive the images of the adjusted rendering without using the one or more corrective lenses. The perceived images are perceived with approximately a baseline normal visual acuity for the human population.

generating, by a processing unit, the ocular information quantifying the deviated visual acuity of the human, wherein the quantified ocular information is mathematically calculated using parameters of the different linear transforms applied to the test visual content before being visually presented, by the computing device, to the human.

6. The method of claim 1, wherein the processing unit used for the identifying the ocular information is the processing unit used for establishing the linear algebraic transform and for visually presenting the images to be rendered.

7. The method of claim 1, wherein the computing device comprises one or more processing units used for the identifying, the establishing, and the applying steps.
