    摘要： An anti-fog article is obtained by coating a substrate with an anti-fog coating material to form thereon an anti-fog coating film that is hydrophillic, moisture-absorptive, insoluble and excellent in surface hardness. The anti-fog coating material contains a polyacrylic acid compound, polyvinyl alcohol and acetylacetone, and optionally sodium silicate.

    摘要： An observation optical system whose eye relief is below 25 mm includes an eyepiece lens (7) having a water absorptive antifogging coating (21) applied on one surface thereof, and a member holding the eyepiece lens (7). Further, an eyeball-characteristic detecting system includes a light source for illuminating the eyeball of an observer, a light receiving element arranged on detection of the reflected light from the eyeball (201) through the eyepiece to produce a signal, an optical member positioned in the path of the light from the light source to the light receiving element and having an antifogging coating (21) on one surface thereof, and a circuit receptive of the signal for detecting the characteristic of the eyeball (201).
