VISION ASSISTANCE DEVICE

摘要

A vision assistance device includes a lens (112) based on a transparent material, a conductive transparent thin film (114) contacting the lens (112) and containing carbon nanotubes, electrodes (115, 116) electrically connected to the conductive transparent thin film (114), and a portable power supply (117) electrically connected to the electrodes (115, 116). The vision assistance device prevents fogging and retains heat.
