What ethical considerations and future steps are necessary before human trials?

The ethical implications of enhanced vision, beyond blindness treatment, require careful consideration, especially regarding potential military or technological applications. Future steps include optimizing manufacturing, ensuring regulatory compliance, and conducting long-term efficacy studies before human trials are ethically permissible; implanting it in individuals with healthy eyesight is considered unethical.

How were these contact lenses developed, and what were the key challenges in their creation?

Unlike night vision devices, these contact lenses don't require external power. The lenses' transparency allows simultaneous viewing of infrared and visible light; however, tests show infrared vision is more accurate with closed eyes due to reduced visible light interference. This technology is currently limited to intense infrared sources.

How does the functionality of these infrared contact lenses compare to existing night vision technologies?

This innovation builds upon the existing understanding of light and its interaction with nanoparticles. By harnessing the energy of infrared light, the contact lens translates it into a visible spectrum, mimicking the infrared vision found in some animals. The resulting images are currently blurred, though.
