Disclosed is an eye examination apparatus that can be used in professional settings. The eye examination apparatus has a body having a first eye opening and a second eye opening for a user to see into the eye examination apparatus using two eyes. The eye examination apparatus also has a first camera coupled to the body and positioned to acquire ophthalmic images through the first eye opening, and a second camera coupled to the body and positioned to acquire ophthalmic images through the second eye opening. The eye examination apparatus also has at least one display coupled to the body and positioned to be viewable through the first eye opening and the second eye opening.

A vision test apparatus includes a hollow housing, a converging lens, and a diverging lens. The converging lens is arranged in the hollow housing, and includes a converging focal length. The diverging lens is arranged in the hollow housing at intervals relative to the converging lens, and includes a diverging focal length. Two optical axes of the diverging lens and the converging lens are overlap each other, and the diverging focal length partially overlaps the converging focal length. One end of the hollow housing adjacent to the diverging lens attaches a test optotype displayed by a display apparatus. The diverging lens demagnifies the test optotype to form a first virtual image within the converging focal length. The converging lens magnifies the first virtual image to form a second virtual image for a vision testing.
