Morphology
Part of the meaning can be guessed because 'eyeball' = eye and 'one/1' together with the model-label pattern 'Mark I' suggests a first or basic version, i.e. unaided, human sight. However, many B1 learners will not recognise the 'Mark I' naming convention (and the given gloss lists 'mark' as a verb), so the intended sense is not fully predictable without prior exposure.
Etymology
The phrase mark 1 eyeball may come from the habit of calling the first model mark 1 and the simple human eyeball. The picture is the original, basic eye, so the phrase means using your own 'direct sight' or looking 'without tools'.
