Self-Evaluation of Visual Accommodation

Exclusively Licensed

In exemplary implementations, this invention is a tool for subjective assessment of the visual acuity of a human eye. A microlens or pinhole array is placed over a high- resolution display. The eye is brought very near to the device. Patterns are displayed on the screen under some of the lenslets or pinholes. Using interactive software, a user causes the patterns that the eye sees to appear to be aligned. The software allows the user to move the apparent position of the patterns. This apparent motion is achieved by pre- warping the position and angle of the ray-bundles exiting the lenslet display. As the user aligns the apparent position of the patterns, the amount of pre-warping varies. The amount of pre-warping required in order for the user to see what appears to be a single, aligned pattern indicates the lens aberration of the eye.
