Abstract
Near-to-eye displays within head mounted devices offer both users with and without visual impairments enhanced visual experiences either by improving or augmenting their visual perception. Unless the user directly views the display without intermediate optical elements then the designer must consider chromatic as well as other aberrations. Within the prior art the optical train is either complex through additional corrective elements adding to weight, cost, and size or through image processing. However, real time applications with mobile users require low latency to avoid physical side effects. Accordingly, it would be beneficial to provide near-to-eye displays mitigating these distortions and chromatic aberrations through pre-distortion based electronic processing techniques in conjunction with design optimization of the optical train with low weight, low volume, low complexity, and low cost. Further, it would be beneficial to exploit consumer grade low cost graphics processing units rather than application specific circuits.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
