TDK demonstrates retinal-projection smart glasses at CEATEC

• 

  TDK demonstrated smart glasses that project images directly onto the retina at the CEATEC technology exhibition.

• 

  The prototype uses TDK’s met aoptics mirror, which the company describes as the world’s first of its kind.

• 

  The mirror is 150 nanometers thick and has 80% visible-light transmittance, comparable to ordinary eyeglass lenses.

• 

  TDK says the glasses can show clear images regardless of eyesight while keeping both the real-world view and projected image in focus.

• 

  The prototype currently supports monochrome images, and TDK aims to demonstrate and mass-produce a full-color version within several years.

Who

TDK demonstrated the smart glasses.

What

A prototype projects images directly onto the retina using a metaoptics mirror.

When

October 13, 2026, when CEATEC opened.

Where

CEATEC at Makuhari Messe in Chiba, Japan.

Why

The design aims to provide clear projected images while avoiding the bulky curved mirrors that made earlier retinal-projection glasses look unnatural or obstruct vision.
