Premium Fit, Premium Price: Ray‑Ban Meta Optics for Prescription Glasses

Engadget’s review of Ray‑Ban Meta Optics finds second‑gen frames offer a noticeably better, more discreet fit with swappable nose pads and moldable tips, plus longer battery life and a new action button. However, the base $499 price plus expensive prescription lenses can push total cost beyond $700, and Meta’s privacy concerns—especially around data use and potential facial recognition—make it a niche purchase for those who need vision correction and value comfort.

"Advancements in Ultra-flat Optics for Broadband Thermal Imaging"

A multi-institutional research team, led by the University of Washington, has developed ultra-thin meta-optics for broadband thermal imaging, addressing the need for lighter and thinner imaging systems with uncompromising image quality. Leveraging a new design framework called "MTF-engineering," which incorporates artificial intelligence and a figure of merit, the team demonstrated thermal imaging with meta-optics in both laboratory and real-world settings. The research represents a significant step toward achieving imaging quality comparable to commercial refractive lens systems, and the team has made their framework available for use in designing meta-optics.

Meta-optics reveals attosecond physical processes in vacuum tunnel.

A new meta-optics for microscopes with extremely high spatial and temporal resolution has been developed at Harvard and successfully tested at Graz University of Technology. The lens of the microscope has made it possible to use extreme ultraviolet radiation for the first time, enabling it to follow ultra-fast physical processes in the attosecond range. The possible applications for the new research field of attosecond microscopy are manifold, especially in semiconductor and solar cell technology.
