title: Accommodation as the primary cause of low-luminance myopia. Experimental evidence.
abstract: Low-luminance myopia of subjects with one normal eye and one aphakic eye was measured with a laser optometer. Low-luminance myopia was registered in the normal eyes, but no such myopia could be found in the aphakic eyes. The same subjects' aphakic eyes were further tested with miotic and dilated pupils. Miosis or mydriasis did not significantly alter the results as compared with measurements obtained with normal pupil size. These results would appear to be the first direct experimental evidence that accommodation is the primary cause of low-luminance myopia.
