The spectacles consist of a spectacles frame, spectacle lenses and opaque material layers.

由镜架、眼镜片和不透明材料层组成。

These layers acted like the anti-reflective coatings on spectacle lenses and caused almost all the sunlight falling on the device to be absorbed.

这些覆盖层的作用就像眼睛镜片上的防发射层一样，因此差不多所有的照到装置上的太阳光都被吸收了。
