Abstract
(EN)
This lens is provided with: a transparent first substrate; a transparent second substrate provided facing the first substrate in the thickness direction of the first substrate; a first optical characteristic varying portion which is provided between the first substrate and the second substrate, and which has an optical characteristic which is varied by means of electric control; and a second optical characteristic varying portion which is provided between the first substrate and the second substrate, is provided displaced with respect to the first optical characteristic varying portion in the thickness direction, and which has a optical characteristic which is varied by means of electric control.
