Optical module for protecting human eyes

An optical module for protecting human eyes, comprising:

• a first support element having a bottom plate and a sidewall on the bottom plate, wherein an accommodating space is surrounded by the sidewall;
• a plurality of first conductive paths in the first support element, wherein each of the first conductive paths has a first end and a second end, the first end is adjacent to a top surface of the sidewall, and the second end is adjacent to the bottom plate;
• a lens above the accommodating space and located on the top surface of the sidewall;
• a metal bonding layer bonding between the top surface of the sidewall and the lens, and having a plurality of openings, wherein positions of the openings are respectively correspond to positions of the first ends of the first conductive paths, and the lens is located on the metal bonding layer;
• at least one second conductive path on the lens and electrically connected to the first ends of the first conductive paths;
• and
• a light-emitting element located on the bottom plate of the first support element, wherein when a resistance difference is detected through the first and second conductive paths, the light-emitting element is switched off.
