Abstract: An ophthalmic lens includes a first lens group having a positive refractive power, a second lens group having a positive refractive power, and a third lens group having a positive refractive power. The first lens group includes a first lens, and a lens in the second lens group closest to the first lens group is a second lens. The ophthalmic lens satisfies the condition of 0.65

Abstract: An imaging lens includes a first lens, a second lens, a third lens, a fourth lens and a fifth lens with refractive powers arranged in order from an object side to an image side of the imaging lens. The first lens is closest to the object side as compared with any other lens with a refractive power in the imaging lens, and the fifth lens is closest to the image side as compared with any other lens with a refractive power in the imaging lens. The imaging lens satisfies the conditions of 0.5
