This strange crystal acts like metal and glass at the same time

Researchers have discovered that the crystal molybdenum oxychloride (MoOCl2) exhibits unique optical properties, acting like metal or glass depending on its orientation. This material's extreme light-bending capabilities could enable the development of ultra-thin optical components for future AR glasses and smart lenses.
Why it matters
This material science breakthrough could significantly reduce the size and complexity of hardware required for advanced wearable augmented reality devices.
Creating nearly invisible wearable technologies such as smart contact lenses and ultrathin augmented reality (AR) glasses will require a radical redesign of conventional optical components. Instead of relying on bulky lenses and hardware, researchers are exploring materials that can manipulate light at the atomic scale.
