PROBLEM TO BE SOLVED: To provide a light irradiation device for lens substrates, in which the lens substrate can be exposed uniformly to light when the lens substrate is irradiated with light and to provide a method for producing a lens.SOLUTION: The light irradiation device (1) for lens substrates includes: a long light source (111); a substrate holding means (131) for clamping the lens substrate (S) at the position opposed to the long light source; rotating means (132, 133) for rotating the lens substrate; and a repetitive movement means (14) for repetitively moving at least one of the lens substrate and the long light source so that the center of a light quantity distribution to be formed by the long light source is made to pass through, at least, a zone from the center of the lens substrate to one end thereof. |
