The practical utility of the dark focus came under serious doubt, however, when different measurement techniques - particularly those using objective, infrared optometers - yielded discrepant dark focus values.
One possible interpretation of this discrepancy is that measures from infrared optometers are more valid because they are not contaminated by subjective factors (such as perception of nearness; Rosenfield & Ciuffreda, 1991) that may be idiosyncratic to the laser optometer.
