I have Russian binoculars (BPC 7x50), looks like, maybe WWII or fow years latter, I dont know... Anyway, it has 2 pairs of glasses that you can put over normal, colorless glas (the ones through you look), one pair is red (when you look through it the picture is orange), and others are green. What is the purpose of these glasses??

Red is good for seeing through haze. It also darkens the sky, making bright objects like airplanes stand out better. I don't know what the green filters were good for. Making deserts look better, maybe.

A friend bought a Russian binocular with different colored lens
from a flea market. They had very poor optics and I doubt that they were military issue. Hope yours are different.,

The different color lenses help the eyes see in different situations. Red was probably for bright light, green for low light.

Very likely to help weed out camaflouged objects. They are filters.
