Foveated Lenses

Smart overview of the Invention

Eyeglasses featuring adjustable lenses are designed to address myopic progression by incorporating advanced optical systems. Each lens can include a switchable liquid crystal diffuser or an array of adjustable microlenses. The switchable diffuser creates a clear foveated region for direct gaze alignment, surrounded by a diffused peripheral region that reduces contrast in the user's peripheral vision. This configuration aids in slowing myopic progression by managing how light is perceived across different regions of the retina.

Technical Details

The adjustable lenses utilize liquid crystal material sandwiched between electrodes, allowing for dynamic control of light diffusion. This setup can involve a common electrode paired with finger electrodes or orthogonal electrode arrays. By applying control signals to these electrodes, the phase profile of the liquid crystal material can be adjusted, enabling selective diffusion and refocusing of light. This technology can preferentially diffuse blue light more than red light, enhancing the focus on slowing myopic progression.

Adjustability and Correction

Lenses are capable of adapting to various vision defects such as myopia, hyperopia, and astigmatism. They can be adjusted for different prescriptions and focal ranges, making them versatile for multiple users. The glasses may also serve dual purposes as spectacles or as components in augmented reality systems, where they can adjust focal planes for virtual content. Additionally, they can include tint layers for outdoor use as sunglasses.

Sensory Integration

Equipped with control circuitry, these eyeglasses integrate sensors like gaze tracking systems to align the clear foveated region with the user's gaze. The sensors may include digital image sensors and lidar for accurate eye tracking. Control circuitry manages the adjustable optical elements based on sensor input, ensuring optimal vision correction and myopic management by dynamically adjusting the lens characteristics.

Power and Communication

The glasses feature control circuitry with processing units and storage capabilities to manage lens adjustments and sensor data. They support both wired and wireless power charging options. Input-output circuitry provides user interaction through touch sensors, microphones, and displays. Wireless communication capabilities enable connectivity with external devices, enhancing functionality in various applications.
