I picked up some used ski goggles that have an orange-tinted plastic lens.

In addition to producing an orange tint, anything lit by sunlight actually seems to be brighter, not darker. For example, my living room is on the opposite side of the building facing the sunlight and somewhat dark. However, when I look at the room through the goggles, the room looks like it's getting direct sunlight and it looks about twice as bright.

This is counter-intuitive since a tinted lens should reduce the perceived brightness -not increase it.

 

Yellow glasses used for shooting do the same. The effect is generally attributed to two factors: 1) Reduction of UV glare, which makes objects appear sharper and brighter; and 2) Removal of blue light causes a reduction in total light, so our pupils dilate slightly. As our eyes are more sensitive to yellow, the yellow that passes seems brighter because of that dilation (https://www.physicsforums.com/threads/why-do-yellow-tinted-glasses-brighten-view.275874/ ).

I notice that the brightness is actually slightly reduced when the room is illuminated with just fluorescent light at night.

 

That's consistent with the model I gave.
