An eye chart (1) of the present invention has a plurality of symbols (14) selected from a set of distinct symbols. The symbols in the set consist of numerals (18) of 3, 4, 6, 7, and 9 and letters (16) of A, E, F, H, J, K, L, P, T, X, and Y. In one embodiment, the symbols in the set further include a pictorial object. A method for vision testing of the present invention includes recording a value associated with an accuracy of identification of at least two of the letter, the numeral, and the pictorial objects on an eye chart by a person, and comparing the values for each eye of the patient. Because these symbols are distinct, the value recorded for visual acuity is accurate and consistent with each recordation. Further, the values are able to be used as aids in testing for neurological disorders or diseases. In another embodiment, the eye chart has symbols of red colors and of black colors. In another embodiment, the eye chart has variously colored symbols on colored backgrounds. Accuracy of identification of these colored symbols is recorded, compared, and used as an aid in diagnosing loss of color vision.
