Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light control devices and methods fail to effectively deliver visual information to the retina at a rate that overcomes natural limitations of visual processing, leading to inadequate vision improvement for subjects with ophthalmic or neurologic conditions, and often interfere with natural neural circuitry.
Innovation Solution
The development of light control devices that optically move apertures anterior to the retina at a rate between 50 hertz and 50 kilohertz, producing regional variation and sampling of the ocular field of view, utilizing see-through displays and waveguides to deliver visual information without replacing natural neural circuitry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional light control devices deliver visual information to the retina, then vision information is transmitted, but the delivery rate is insufficient to overcome natural limitations of visual processing
Solution Approach 1:
The patent applies periodic action by moving apertures at high rates (50-50,000 Hz) to deliver visual information in rapid successive frames. This high-frequency periodic delivery overcomes the natural limitations of visual processing by presenting information faster than the eye can naturally process, thereby improving vision effectiveness without interfering with neural circuitry.
2Reliability
If light control devices interfere with natural neural circuitry to improve vision, then vision improvement is achieved, but natural neural pathways are disrupted
Solution Approach 1:
The patent replaces mechanical interference with neural circuitry by using optical aperture movement instead. Rather than attempting to stimulate or modify neural pathways directly, the system uses high-speed optical aperture relocation to deliver visual information that the natural visual system can process, thereby achieving vision improvement without harmful interference.
3Speed
If apertures are moved at high rates to overcome visual processing limitations, then visual information delivery is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the visual field into multiple regions controlled by separate apertures that move independently. This segmentation allows the system to achieve high-speed visual information delivery across different field regions while managing device complexity through modular aperture control rather than requiring a single complex moving component.
Solution Approach 2:
The patent uses another dimension by moving apertures not only in position but also in time at high frequencies. This temporal dimension (50-50,000 Hz movement rates) allows the system to overcome visual processing limitations without proportionally increasing spatial or mechanical complexity, as the high-speed temporal modulation can be achieved through electronic control rather than mechanical complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The devices enhance vision by improving visual perception, stabilizing it, and correcting ophthalmic or neurologic conditions, reducing the rate of vision loss, and monitoring vision without interfering with natural neural pathways.
Implementation Method 1
move optically one or more apertures anterior to a retina of an eye between one or more positions anterior to the retina that are non-coaxial with a center of a pupil and a position anterior to the retina that is coaxial with the center of the pupil
Implementation Method 2
The electrical component can direct an electrical current through each of the transparent carrier layers, and the directed electrical current can electrify the one or more active optical elements to create and move the one or more apertures
Implementation Method 3
The light control device can also include one or more waveguides, and the light control device can move the one or more apertures using the one or more waveguides

AI summary
Exemplary light control devices and methods provide a regional variation of visual information and sampling (“V-VIS”) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods generate a moving aperture effect anterior to a retina that samples and delivers to the retina environmental light from an ocular field of view at a sampling rate between 50 hertz and 50 kilohertz. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.
