An ophthalmic apparatus capable of suppressing ghost, and securing a necessary amount of working distance even when an eye to be inspected has a diopter on a myopia side, includes: a large area image acquisition unit acquiring a large area image of a fundus of the eye to be inspected at a low resolution based on return light of first measuring light from the fundus; a small area image acquisition unit acquiring a small area image of the fundus at a high resolution based on return light of second measuring light from the fundus; and a dichroic prism combining the first measuring light and the second measuring light, and dividing the return light, in which the large area image acquisition unit includes an optical member having a positive optical power, which is arranged at a position opposite to the eye to be inspected with respect to the dichroic prism.
