[Cataracts and contrast].
The value of visual acuity in patients with incipient cataract, as measured using the conventional Snellen charts amounts to normal or near normal values (6/9-6/6). Nevertheless, their contrast sensitivity determined using the Ginsburg charts or optotypes with lowered contrasts is markedly depressed. The measurement of the visual acuity alone is insufficient diagnostic purposes in these patients.
