Yi Seed can Change Shi Visual Net film Examination Guang Xi System, go out comprising building Agencies an optical path Trail Yi Guang Learn Mo Group, Let set on The optical paths Trail one projection object, Ji mono- Hair Guang Mo Group. The Hair Guang Mo Group have mono- Bei Jing Hair light parts of Yi Zhu Hair Guang Jian With. The main Hair light part With The back scape Hair light parts of The divide the aforementioned optical path Trail Productivity of the Do phases Right light Line of raw different colour systems, make the Visual Net films of one eyes of image projecting what of The missiles. Thereby, the shape Like for cooperating The missiles, in the case of not needing Geng Change missiles, the bias light of the raw effects of Yi Tong Time Productivity, and change the mode of Change bias light Yan colors, Examination Guang Time Quasi Indeed are substantially improved.一種可變式視網膜驗光系統,包含建構出一光路徑的一光學模組、設置在該光路徑上的一投影物,及一發光模組。該發光模組具有一主發光件與一背景發光件。該主發光件與該背景發光件分別相對前述光路徑產生不同色系的光線,使該投射物的影像投影於一眼睛的視網膜。藉此,配合該投射物的形狀,在不需要更換投射物的情形下,以同時產生作用的背景光,及改變背景光顏色的方式,大幅提升驗光時的準確性。
