Abstract

A virtual reality (VR) system can be implemented to adjust visual complexity based on real-time eye fatigue monitoring. The system utilizes an electronic device that includes a head-mounted display (HMD) and eye-tracking sensors. The device generates a VR user interface corresponding to a three-dimensional virtual environment and renders it on the HMD. While the user interacts with the virtual environment, the system continuously monitors their eye movements and behavior using the eye-tracking sensors. The system analyzes this data to detect signs of eye fatigue. Based on the detected eye fatigue, the system dynamically adjusts the visual complexity of the VR user interface in real-time.

Abstract

A vision test can be implemented in a virtual reality (VR) environment using a computer device that includes a head-mounted display (HMD). The computer device can obtain historical vision data of a patient user. Based on the historical vision data, the computer device determines an ordered sequence of vision tests including a first vision test for the patient user. The first vision test is followed by a set of one or more subsequent vision tests of the ordered sequence of vision tests. The computer device executes a user application configured to enable the ordered sequence of vision tests by rendering a user interface on the display. A first visual stimulus of the first vision test is displayed on the user interface. The computer device obtains a user response to the first visual stimulus, and dynamically adjusts one or more subsequent visual stimuli based on the user response.

Abstract

Eyeglasses can protect wearers from discomfort and inconvenience caused by fogged-up eyeglass lenses or blue light and glare induced vision fatigue. Some aspects of the present disclosure relate to an eyeglass lens with a resin lens, a hardened layer, an anti-reflection coating, and an optional anti-fog coating. The anti-reflection coating and the anti-fog coating can be vacuum coated onto the resin lens and the hardened layer by an electron gun. This layered structure makes the eyeglass lens resistant to condensation. Some aspects of the present disclosure relate to an eyeglass lens with a resin lens, a hard coating, an anti-reflection coating, and an ultra-hydrophobic layer. The hard coating can be dip coated onto the resin lens, and the anti-reflection coating can be vacuum coated onto the hard coating. This layered structure reflects blue light to limit the amount of vision fatigue experienced by the wearer.
