Are Kalichrome Lenses Effective In Hazy Environment?

Numerous authors have advocated the use of yellow tinted lenses (henceforth, the tradename Kalichrome will be used) in hazy or foggy environmental conditions to improve visibility. Many observers report that the apparent increase in brightness associated with the application of the Kalichrome lenses improves discrimination of the target. Others report an increase in contrast. Professional drivers, hunters, and target pistol enthusiasts, to name a
few, feel that these qualities of the Kalichrome lenses will improve their respective task performance relative to Kalichrome lens application.
