Abstract : Twenty subjects made a total of 400 threshold visual acquisitions of T-38 aircraft approaching from 9 miles out. Half of the acquisitions were made with the subjects wearing yellow ophthalmic filters, and the other half without filters. The researchers found no overall statistically significant difference in acquisition performance due to the use of yellow filters. (Author)
