That light from the sun (and space - ie. other suns and gas clouds, etc - no matter how infinitesimally small) that passes through the atmosphere, and directly and indirectly (after bouncing around off other subjects) lights our target subject and then further passes through haze, smog, atmospheric turbulence, glare etc before reaching the outer coating of the objective lens we can regard as 100%.  From that point the losses start - different wavelengths are affected to different degrees by mechanisms of reflection and transmission, absorbtion, heat dissipation etc.  It's not like your 80, or 92% transmitting binocular transmits that as a Nullabor Plain flat spectral graph nice and neatly right from the front without any effects occurring throughout the binocular along the way before hitting your eyeball (and the process from there btw until final interpretation by tha grey stuff in ya noggin' is a whole 'nuther story -- suggest peeps look up Gij's excellent treatise on the subject for further info <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /> ....... NoSiree!  Each coating layer slightly modifies the raw data that is sent to it, and only in concert as an overall integral (along with all the other losses) transmute that original target subject image that reaches the outer extremitities of the objective into the one that forms at the exit pupil. All of those losses add up to 'visual junk' that leads to degradation (no matter how small) of the original image   :cat:Designers and manufactures go to great lengths (or not <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />  and spare no expense (or do <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />  in an effort (or not <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />  to minimize this degradation.  They also 'block' certain frequencies such as the Ulta Violet range to protect our eyesight, seek to balance colour representation, and overcome physical limitations with transmission etc.  Thus they each arrive at a different (though broadly the same) 'Flava' of the actual view represented according to the economic, knowledge, design, and manufacturing limitations of the ideal or practical criteria laid down.  What we actually want is more transmission -- not less!  :t:3<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />Bring on the 100% transmission binoculars with deep space nanocarbon black coated internal tube surfaces ........ :clap:Of course you won't be able to look directly at intense reflected sunlight off bright chrome surfaces (it's been quite a while since I've seen a chrome bird anyways <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />, water etc, but I would much rather choose not too, or elect to wear sunnies etc, rather than have the bin limited by 20 -10% inherent transmission loss (along with it's associated image degrading crudola) which at other times is most inconvenient!  Chosun  :gh:</blockquote>
