1. A transparent or translucent coated article having a perceived reflectance F, wherein F=∫



  • S(λ



    )R(λ



    )dλ



    whereλ

    is wavelength, θ

    is incident angle, S(λ



    ) is human sensitivity function as a function of the wavelength and the incident angle, and R(λ



    ) is an average of p- and s-polarized reflectances, the coated article comprising;

    an optical substrate; and

    one or more layers of anti-reflection material coated on at least a portion of the optical substrate, said one or more layers of anti-reflection material having a thickness such that the perceived reflectance of the coated article is less than or equal to 1.25Fmin, where Fmin is a minimized perceived reflectance of the coated article.
