Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
We propose to test the hypothesis that regional changes in the choroidal thickness may be induced differently after short-term exposure to specific visual stimuli.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
normal healthy group
Adaptive optics system: this system controls the optical quality of the eye at the peripheral visual field temporarily.
adaptive optics system
the system consists of a wavefront sensor and a deformable mirror that measure and correct (or modify) the eye's optical imperfections (aberrations).
