Abstract: A programmable graphic projection light source system for ophthalmology includes a light source, a flexible screen, a reflective coating, and a light-shielding plate that is located between the light source and a pupil. The light source irradiates light away from the light-shielding plate. The flexible screen is located opposite the light-shieling plate crossing the light source. The reflective coating is located opposite the light source crossing the flexible screen.

After the light is reflected by a plane portion of the reflective coating, a part of the light transferring the pattern irradiates obliquely onto the pupil.
