The eye-protection glasses against YAG laser disservice based on the bandgap reflection of one-dimensional photonic crystal is designed and manufactured. The light with wavelength of 1.06μm is reflected by the bandgap of one-dimensional photonic crystal (with the transmission below 10
-7
) and absorbed by the phosphatic glass substrate (with the transmission of 1%). It makes the glasses to be enough to protect the eyes from the disservice by ns-YAG laser with power energy of 1J/cm
2
for all incident angle. The glasses have the transmission beyond 70% for the visible lights
and avoid the second disservice to others by the reflected light from the glasses. The testing data of the eye-protection glasses agree well with theoretical calculations.
