摘要：A method to find a visual axis of an eye includes illuminating a light sourcepinhole by a light including at least two different wavelengths; projecting an image of the
light source pinhole through a translatable pinhole and through a pupil of the eye onto aretina of the eye; generating a projected image of the translatable pinhole on an anteriorsurface of the eye or a contact lens; adjusting a position of the translatable pinhole in aplane about parallel to a plane of a cornea of the eye until two different dots viewed onthe retina merge into one dot; and indicating by the projected image of the translatablepinhole a location of where the visual axis of the eye intersects the cornea or the contactlens. An apparatus to measure a visual axis of an eye is also described.
