A cornea shape measurement apparatus includes: a first projecting optical system configured to project a first target on the cornea a first imaging optical system configured to capture a reflection image of the first target projected on the cornea a second projecting optical system configured to project a second target different from the first target on the cornea to measure a corneal shape a second imaging optical system configured to capture a reflection image of the second target projected on the cornea and a calculation controller configured to adjust the amount of projection light of the second projecting optical system based on the reflection image of the first target, the reflection image having been acquired by the first imaging optical system, and measuring the corneal shape of an examinees eye based on the reflection image of the second target, the reflection image having been captured by the imaging optical system.
