The modified dynamic scaling hypothesis is formulated, which describes the non-equilibrium physical properties (in particular, features of light critical opalescence spectrum) for the spatially limited one-component nearcritical liquids. The dependence of width $Γ_{c}$ of the central component of Rayleigh line is obtained for liquids in a small volume of cylindrical geometry. It is shown that a reduction of the characteristic size of the system (for the chosen geometry – the radius of a cylinder)\textbf{ }leads to an increase in width $Γ_{c}$ of the central component.
