Message: <blockquote data-quote="Gilmore Girl" data-source="post: 3308815" data-attributes="member: 106744">My polycarbonate eyeglass lenses reveal subtle CA at times.  I only noticed it when I first began wearingthem, but now I don't see it anymore.  I assume that some CA seen through my bino could be, to some degree, caused from the eyeglasses.  Also, I know that if the EP is not aligned to my eyes properly then some CA will show at times...this is the difficulty with eyeglasses.CA is one of those things that, if controlled well enough in the center, I don't care much about.  If I happen to see a bit of it I'm not really bothered and normally I don't even notice it.    Also, CA has to be really bad to prevent positive ID of birds.It seems two top binos for CA control are the Kowa Genesis and Zeiss FL T.  At least, this is what I gleaned from reading user comments over the years on this forum.  I've never seen the Genesis in person...would like to and very curious if an updated model will come out in the near future.  Zeiss FL 8x32 I looked through several times...very nice.I never owned a  top $2k bino... I tried recently with the Ultravid HD Plus 8x32 (one I've always desired)...alas, ER is too short with my eyeglasses...total bummer and now I don't want to think about buying anything else.  I will stick with my Opticron for now...it gets the job done...it's quite good actually.</blockquote>
