1. A method comprising:
- obtaining a visual parameter associated with a degree of severity of a vision impairment of a viewer;
receiving content for display;
modifying display characteristics of the received content according to the visual parameter to generate modified content, the modified content comprising a plurality of reproduced objects, generating the modified content comprising;
determining an object within the received content to reproduce, wherein the object comprises a pixel or a group of pixels;
generating the plurality of reproduced objects based on the object;
determining an offset amount using the visual parameter, the offset amount varying in response to varying severity of the vision impairment of the viewer; and
generating the modified content including the plurality of reproduced objects offset from one another along an axis by the offset amount;
rendering the modified content on a rear display; and
selectively activating a front barrier display to control visibility of the modified content according at least in part to the visual parameter, selectively activating the front barrier display to control the visibility of the modified content comprising;
controlling one or more first areas of the front barrier display to cause a first portion of the modified content rendered on the rear display to be visible to the viewer using the visual parameter; and
controlling one or more second areas of the front barrier display to block a second portion of the modified content rendered on the rear display from visibility by the viewer using the visual parameter.

Abstract
Disclosed are various embodiments that relate to a display that renders corrected images to viewers so that users do not need to wear corrective lenses. The system obtains a vision parameter associated with a viewer and/or content to be displayed. The system receives an image for display to the viewer and modifies the image according to the vision parameter to generate a modified vision corrected image. The system renders the modified region on a rear display while rendering a selective barrier on a front barrier display to direct a vision corrected image to a viewer according to the vision parameter.
