摘要

A red/green tester judging whether a glass lens or a contact lens is corrector not, or suitable or too strong, has a case (1). The inside of the case (1)is divided into left and right divisions by a partition plate (2). A red testlamp (3R) and a green test lamp (3G) are provided on the left and right sidesof the partition plate (2), respectively. A red film (5) and a green film (6)are provided on the front of the case (1) on the left and right sides of thepartition plate (2) respectively through an opal screen (4). Black fixed marks(8 and 9) which have identical patterns and sizes are provided in thepositions corresponding to the lamps (3R and 3G) on the fronts of both films(5 and 6). A switching circuit which, after operating or flashing the lamp(3G) for a certain time, operates the lamp (3G) and the lamp 3R simultaneouslyis provided. Thus, the red/green mark test can be carried out while theadjustment of the crystalline lens which is performed by the subjectunconsciously can be avoided as much as possible.
