Static retinoscopy results with and without a fogging lens over the non-tested eye

This study addressed the question: "Should both eyes be fogged during static retinoscopy?" Static retinoscopy measures were taken on young patients. (N = 50; mean age = 9 years, 4 months). Outcomes revealed no differences except with hyperopic patients, where the lack of a fogging lens over the partner eye resulted in a significant underestimate (p less than .001) of the refractive status. This argues against the use of a lens bar for retinoscopy especially in vision screening programs involving young children.
