眼鏡レンズの色収差と視機能におよぼす影響

抄録

Four kinds of ophthalmic lenses which have different Abbe numbers (v_d) with the same refractive index (n_d) for 588 nm have been prepared for our study. They have different chromatic aberrations even though they have the same powers.
In the first, axial and lateral chromatic aberrations of these lenses were calculated and measured. Then, the white light MTF curves of the visual system of the wearers were measured to estimate the influences of the chromatic aberrations.
As the results, it became clear that one can neglect the axial chromatic aberration in general. The lateral chromatic aberration, however, decreases the visual acuity of the subject considerably who sees through an eccentric portion of the lenses.
