Can't speak for the contacts but Transitions Xtractive also react to visible light, albeit not as strongly as for UV. Mine tint noticeably behind a windshield or inside a motorcycle helmet (and, unfortunately, large-windowed conference rooms). Never had issues in tunnels or buildings such that I needed to remove them though.
