Korean researchers shrink augmented reality lenses to fit everyday eyewear
Researchers in Korea have developed an ultrathin optical lens system that keeps digital images bright and legible even in direct sunlight, overcoming one of the main engineering hurdles preventing augmented reality glasses from looking and feeling like ordinary eyewear. The joint team from Pohang University of Science and Technology (POSTECH) and Samsung Research built a prototype featuring a…
Korean scientists have successfully engineered an ultra-thin optical lens system that enables augmented reality glasses to remain bright and clear, even under direct sunlight. This breakthrough addresses a significant challenge in developing wearable AR devices that mimic the appearance and feel of standard eyewear.
The research, a collaboration between Pohang University of Science and Technology (POSTECH) and Samsung Research, resulted in a prototype featuring a 1.5-millimeter-thick waveguide. This transparent channel directs light from a small projector into the user's eye, utilizing engineered nanostructures called metasurfaces. The findings were recently published in the journal Nature, as reported by the Ministry of Science and ICT.
For years, major technology companies such as Meta, Apple, Google, and Samsung have been striving to create lightweight smart glasses capable of overlaying information like turn-by-turn directions, translations, and messages onto the real world. However, engineers have faced a persistent trade-off: widening the viewing area to enable users to look around without losing the image usually results in light scattering and leaking out of the lens, diminishing the overall effectiveness.
