FIELD: process engineering.
SUBSTANCE: proposed method comprises the stages that follow. Single substrate with optical quality zone is brought in contact with reactive mix to transmit actinic radiation through said single substrate so that portion of said reactive mix is polymerised and ocular lens workpiece is formed. Transmission of said actinic radiation is controlled by voxels. Ocular lens workpiece comprises first and second surface sections in optical quality zone, second section being formed in free manner. Proposed method comprises the stages that follow. Ocular lens workpiece is formed with first and second surfaces by irradiating reactive mix with first actinic radiation transmitted through the substrate. Note here that transmission of said actinic radiation is controlled by voxels to spread first portion of fluid over second surface and to irradiate lens workpiece with second actinic radiation.
EFFECT: lens with preset sizes and geometry.
