摘要：
n n n n n n n Picture for duochrome test of a person with astigmatism with known angle (O) of cylinder where each color part (R G) comprises at least one tuple or is composed of at least one tuple where n is at least 2 parallel lines oriented according to determined angle of cylinder (O) of the person with astigmatism to which at least one tuple identical parallel lines is perpendicularly associated whereas line thickness (h) in the tuple is 0.035 to 6 mm distance (d) between lines in the tuple is 0.035 to 6 mm distance between two geometric centres of neighboring tuple lines is at least equal to the length (L) of the lines and the length (L) of each line in tuple is at least 0.105 mm.
