As mentioned above, the composite glass/plastic laminated optical lens structure of the aforementioned US Patent No. US-4793703 is obviously formed by combining the inorganic glass layer, the organic plastic layer and the adhesive layer, so there is no functional film layer in the inorganic glass layer, the organic plastic layer and the adhesive layer.

As mentioned above, the composite glass/plastic laminated optical lens structure of the aforementioned U.S. Patent No. US-4793703 includes an inorganic glass layer, a first organic plastic layer, a second organic plastic layer, a first adhesive layer and a second adhesive layer.

In addition, the middle layer is a color-changing layer, and the color-changing layer includes a photochromic dye. Between the front lens and the rear lens, the support structure can define a uniform thickness space, so that when the photochromic dye is filled into the uniform thickness space, a uniform thickness layer can be formed.

As mentioned above, the aforementioned US Patent Publication No. US-20150049303 has an outer surface on the front lens, and a functional coating can be optionally combined on the outer surface of the front lens, and has an inner surface on the rear lens, and another functional coating can be optionally combined on the inner surface of the rear lens.
