Where's the science on "blue light exposure?" I'm thinking that since the claims on eyeglasses are suspiciously vague, that it's all just a way to up-sell.
What's more, is that I happen to be a fan of blue light, and don't want the colors I see all day distorted. If I want less "blue light exposure" from screens, then I can tune the screen.
If your blue-blocking glasses don't change how things look in the visible spectrum, then which spectrum of light are you blocking?
Fun with Water Bubbles
Artemis II astronauts having fun as they showcase the unique behavior of a ball of water in a microgravity environment. In space, a ball of water moves and shapes light in surprisingly complex ways.

South Korean startup LetinAR is pioneering the development of optical modules for AI-enabled smart glasses, a key component that determines usability, image clarity, and power efficiency. Founded in 2016 by longtime friends Jaehyeok Kim and Jeonghun Ha, LetinAR has spent the last decade perfecting its proprietary technology called PinTILT. Unlike traditional waveguide or birdbath lenses, PinTILT directs light precisely into the user's eyes, producing brighter images in thinner, lighter, and more energy-efficient lenses. This innovation addresses the major challenges in the wearable AI glasses industry, where every gram and battery hour counts. LetinAR has already secured $18.5 million in funding from Korea Development Bank and Lotte Ventures, with total funding reaching $41.7 million, and plans a 2027 IPO in South Korea. Its optical modules are currently used by companies like Japan's NTT QONOQ Devices and Dynabook, as well as in a Swiss AI-powered AR motorcycle helmet from Aegis Rider, set to launch in European markets in 2026. As global AI glasses shipments continue to surge—8.7 million units in 2025, projected to exceed 15 million this year—LetinAR positions itself as a critical supplier enabling wearable, practical, and high-performance AI glasses.

Ultrafast events in matter happen in femtoseconds, too fast for standard cameras.
A new imaging method now captures both light intensity and phase in a single shot, revealing hidden microscopic dynamics in real time.

Researchers have developed a new imaging technique that captures more information about ultrafast processes in the microscopic world than was previously possible. The technique offers scientists a powerful new tool to observe and analyze a wide range of ultrafast phenomena—which can happen in hundreds of femtoseconds—with unprecedented detail and speed. Writing in Optica, the researchers describe their new ultrafast imaging technique, called compressed spectral-temporal coherent modulation femtosecond imaging (CST-CMFI).
