Antireflective switchable glass construction

A method of reducing reflectivity in a switchable laminated glass construction, comprising:

• forming a glass lamination stack comprising
• a first glass substrate;
• a second glass substrate;
• a switchable functional film between the first and second glass substrates, wherein the switchable functional film comprises
• a switchable material layer,
• a first polymer substrate formed with a first transparent conductive coating, wherein the first polymer substrate is between the first glass substrate and the switchable material layer,
• a second polymer substrate formed with a second transparent conductive coating, wherein the second polymer substrate is between the second glass substrate and the switchable material layer, and
• at least one index-matching layer between the first transparent conductive coating or the second conductive coating and the switchable material layer;
• a first adhesive polymer interlayer between the first glass substrate and the switchable functional film;
• and
• a second adhesive polymer interlayer between the second glass substrate and the switchable functional film;
• and
• de-airing and autoclaving the glass lamination stack to provide the switchable laminated glass construction;
• wherein at least one of the first adhesive polymer interlayer and the second adhesive polymer interlayer is at least one darkened layer-having a darkness for reducing reflectivity from at least one of the first and second transparent conductive coating layers,
• wherein the switchable laminated glass construction has a reflectance equal to or less than 13% in a transparent state, as measured from at least one side of the switchable laminated glass construction.
