An eye observation apparatus includes a non-translucent peripheral frame member, a cylindrical light-transmitting member, and an imaging unit. The peripheral frame member includes a tight-fit inner cylindrical surface and a clearance-fit inner cylindrical surface. The cylindrical light-transmitting member includes a tight-fit outer cylindrical surface and a clearance-fit outer cylindrical surface, the tight-fit and clearance-fit outer cylindrical surfaces being coaxial with the tight-fit and clearance-fit inner cylindrical surfaces of the peripheral frame member. A radial clearance between the clearance-fit inner cylindrical surface of the peripheral frame member and the clearance-fit outer cylindrical surface of the cylindrical light-transmitting member is greater than a radial clearance between the tight-fit inner cylindrical surface of the peripheral frame member and the tight-fit outer cylindrical surface of the cylindrical light-transmitting member.
