The bifocal lens for eyeglasses is constituted of a single material with a uniform refractive index and is provided with a lens for presbyopia (1B) used for looking at something near at a portion of a body lens part (1A) used for looking at something in the distance. The lens for presbyopia (1B) is formed of an upper side which is generally horizontal when used, a lateral side on the ear side which continues to the upper side and expands toward the ear, and a lower side parallel to the peripheral shape of the lower side of an eyeglass frame to be generally circular-arc or generally rectangular as a whole.
