The present invention generally relates to systems and methods for simulation of web based content. A width of the flow path and a depth of the flow path at the orifice are set to be smaller than a width of the flow path and a depth of the flow path at the light-irradiated portion, and the flow path is configured to gradually decrease from upstream of the orifice in a cross-section area perpendicular to a liquid-delivering direction between the light-irradiated portion and the orifice. Also disclosed are ophthalmic lenses as obtained by the methods which are capable reducing aberrations of the eye.
