Disclosed is a multifunctional screen protector designed to enhance the user experience by integrating multiple advanced features into a single, flexible product. The screen protector incorporates a magnifying lens sheet that provides uniform magnification across the display, aiding users with near-vision difficulties. Additionally, it features an anti-glare coating to improve screen visibility in bright environments, and a blue light-filtering layer to reduce eye strain caused by prolonged exposure to high-energy visible light. To protect user privacy, an embedded privacy filter restricts the viewing angle, making the screen content visible only to the user. The screen protector is adaptable to both flat and curved screens, ensuring broad compatibility with a variety of electronic devices, including smartphones, tablets, and monitors. This invention offers a comprehensive solution that significantly enhances visual clarity, device protection, and user comfort, addressing the limitations of existing screen protectors.

A virtual reality (VR) system can be implemented to identify potential eye strain issues through prolonged engagement. The system employs an electronic device featuring a high-resolution VR headset with integrated eye-tracking sensors. It generates a VR user interface corresponding to a three-dimensional virtual environment and renders it on the VR headset. Within this environment, the system presents a series of progressively challenging visual tasks. Throughout these tasks, the system continuously monitors the user's eye movements and behavior using the eye-tracking sensors. The collected data is then evaluated for indicators of eye strain, potentially allowing for early detection and intervention in cases of visual discomfort during extended VR use.

A virtual reality (VR) system can be implemented to evaluate visual discomfort in users with eye strain sensitivity. The system utilizes an electronic device equipped with a high-resolution VR headset and eye-tracking sensors. The system generates a VR user interface that simulates visually demanding tasks and renders this interface on the VR headset. Within this virtual environment, the system presents a series of interactive scenarios designed to potentially induce visual stress. Throughout these scenarios, the system continuously monitors the user's eye movements and behavior using the eye-tracking sensors. The collected data is then analyzed for indicators of eye strain and visual discomfort, potentially providing insights into individual susceptibility to visual stress and informing strategies for mitigating discomfort in VR and other visually demanding environments.

A photovoltaic photo-thermal lighting comprehensive utilization skylight comprises a plurality of rectangular openings formed in a roof, and each rectangular opening is provided with a skylight body. The skylight comprises a heat insulation lighting window vertically arranged on the south edge of the rectangular opening and further comprises a supporting inclined plate arranged on the north edge of the rectangular opening, and a photovoltaic panel is arranged on the outer surface of the supporting inclined plate. The skylight further comprises a light reflecting plate which is arranged on the inner side of the supporting inclined plate and is parallel to the supporting inclined plate. Distances are reserved between the light reflecting plate and the supporting inclined plate and between the light reflecting plate and the heat insulation lighting window. The adjusting plate is hinged to the upper edge of the heat insulation lighting window. Through reasonable arrangement of component structures, natural light can be evenly distributed to all corners in a room, natural light is effectively introduced, the indoor lighting quality is improved, eye fatigue is reduced, and the visual comfort degree is improved; meanwhile, a ventilation channel is adjusted through an adjusting plate according to indoor and outdoor temperature and illumination intensity, natural ventilation is enhanced through hot pressure difference, indoor and outdoor air exchange efficiency is enhanced, air quality is improved, and indoor refrigeration and heating energy consumption is further reduced.

X-ray images generated by a biopsy tissue handling device are selectively modified to emphasize regions of interest and de-emphasize or eliminate image regions that are distracting, impair viewing attention, and / or cause eye strain. An image processor performs an image mask based on the geometry of a portion of a specimen tray that includes a storage compartment having a tissue specimen. A compartment mask is performed on a portion of an X-ray image that depicts the storage compartment including the tissue specimen. The compartment mask boundary substantially corresponds to the outline of the compartment. A partial structure mask is performed on a portion of the X-ray image that depicts the specimen tray and a corresponding wall of the storage compartment. The partial structure mask boundary extends along a corresponding length and partially through the corresponding wall of the specimen tray.
