In spite of the fact that FIRST explicitly allows lightly tinted Yellow, Rose, Blue, and Amber tints, the generalization, mentioned several times, that tinted glasses are only for outdoor use is too broad.
It is typically the colors listed that are used for contrast enhancement, color correction, and/or glare reduction in an indoor setting as well.
Adding gray to the list would be useful - UVEX, for instance, has a gray lens that still allows 80% of visible light to pass, while reducing the amount of transmitted IR.
