instrument for detecting color-vision anomalies
Etymology
'anomaloscope' originates from modern scientific coinage based on Greek elements: 'anomalos' meaning 'uneven, irregular' and 'skopein' meaning 'to look' or 'to examine'.
'anomaloscope' was formed in scientific/medical usage in the late 19th to early 20th century by combining Greek roots and adopted into English to name an instrument for observing anomalies in color perception.
Initially formed to mean 'an instrument for observing irregularities,' it came to have the specific meaning of 'an instrument for testing color-vision anomalies.'
