What it is
A contact lens with integrated microelectronics for sensing or display.
How it works
Micro-scale power harvesting drives sensors or a single-pixel-class display element within the lens body.
Why it matters
A functional smart contact lens would remove the frame entirely, but safety and power remain unsolved.
Advantages
- Invisible to others
- Always aligned with the eye
Current limitations
- Power delivery
- Heat and oxygen permeability
- Regulatory approval burden
Commercial readiness
Research and prototype only. No consumer product is available.
