What does it mean "ruby coated" on binoculars?
What is that red coating made of anyway, and what is it for and what benefits exactly?
This is what I found regarding ruby coating and its beneifts
Is "ruby" coating available on your binoculars?
No. First of all, the coating has nothing to do with the mineral ruby. Some manufacturers filter red to compensate for poor-quality optics that do not properly converge the color spectrum. By eliminating red from the spectrum, the optics appear to do a better job of minimizing color abberations- but gives the view through the binocular an unnatural greenish cast. Steer clear of "ruby" coating- it's simply a gimmick with no redeeming qualities. We've seen ads from unscrupulous vendors that claim magical "night vision" properties for their "ruby-coated" binoculars - "no batteries required". Rubbish...
