A fibrous structure testable in a series of run-off tests, wherein each run-off test includes exposing the fibrous structure to a volume of a test solution and the fibrous structure initially is hydrophobic and has been treated to be hydrophilic, wherein the fibrous structure exhibits a run-off level that is less than 5 percent by weight throughout a series of run-off tests, and wherein the series starts with a first run-off test and ends with a fifth run-off test.

The invention concerns the preparation of an optical structure. On a polymeric substrate there is first provided a surface activation, and the deposit of a layer of SiO.sub.2, 2000 .ANG. thick after which there is a deposit of a plurality of functional layers and finally a deposit of SiO.sub.2, 3 microns thick followed by a deposit of Si.sub.3 N.sub.4 /SiO.sub.x N.sub.y 3 microns thick, the latter being produced under radio-frequency polarization. The thus obtained optical structure has properties of adhesiveness, resistance to abrasion and to thermal impacts.
