    Porros for less tiresome views as we age?

    Hey, I don't even quite know what I said in that last post, but my advice is don't try to figure it out-if I can't, then forget it! ; ) I was probably tired-that's when words and thoughts go wrong for me. What I have learned lately is that setting the diopter well seems to make a big...

    Porros for less tiresome views as we age?

    No, it's not the bins, it's me I THINK this problem was due to my fatigues eyes, and not my comparison of roofs to Porros, so let's let this go for now. I did find the more I used the Sightron BSII 10x32s, the more comfortable they were for me. I've checked since, comparing them to other...

    Porros for less tiresome views as we age?

    OK, just played around with this, and the BSII's were open slightly more than my measured IPD, so maybe it had some effect on my eyestrain. But I don't remember having any trouble setting the IPD in any bins before-it is a pretty natural step for me in using binoculars. But, what has always...

    Porros for less tiresome views as we age?

    I don't have a particular way to set it, whether opening or closing to it-just til it feels right. I just measured my IPD in the mirror, and then went and measured the BS 10x32s, and they were open a little further than my measured distance. But yes, me too-if it feels constricted, I open it...

    Porros for less tiresome views as we age?

    Yes Bill, you are correct about my query being innocent that truthful. I'm not saying there is a difference, and I really didn't think it through-just surmised at that moment because the Porros seemed so easy to look through, and it seemed I was having a tough time with the roof, so it led me...

    Porros for less tiresome views as we age?

    Another sensible answer and comment, thank you-I set my IPD to what seems right, until I get the one circle without any blur in the middle. But I do sometimes move it around when I am looking very much closer to me, or very much farther away, depending on the binocular. If it doesn't seem off...

    Porros for less tiresome views as we age?

    Dennis, I was only referring to the one roof my eyes were having trouble with, the Blue Sky II 10x32. Now I'm going to have to pull out all my roofs and see if my eyes don't like them now too! But I never felt like this before about them, just since trying this new one out, and comparing with...

    Good point, Alex. Balance could indeed have a good or bad effect, but I didn't think of that for being able to hold lighter bins more steady. Makes sense too! Nice to have more than one head to use, isn't it, when you are looking for answers?! ; )

    Porros for less tiresome views as we age?

    My 8x32 Sightron is pretty much perfect in regard to smoothness, whereas the 10x32 has just the tiniest amount of stiction when you are trying to fine tune it after you stop and manoever back and forth. But I have tried other SII's that weren't as nice as either of these also. What I think...

    Porros for less tiresome views as we age?

    Thank you Arthur, yes, I understand what you are saying, and of course it makes sense. I don't have any other 10x32's to compare with the Sightrons, so was just using what I had to try and understand the differences. I will have a Mojave to compare soon though. One odd thing I did notice was...

    Porros for less tiresome views as we age?

    Well, specifically, I just got the Sightron 10x32 SII Blue Sky roofs, and found that either my cheap Nikon Aculon 10x42's, and my 8x32 EII's both gave an easier view to my eyes, than even the Sightron 8x32 SII Blues Sky roofs too. No fighting with focus with the Porros, to find the best view...

    Porros for less tiresome views as we age?

    Has anyone felt that the Porros promote a less tiresome or stressful view, especially for older eyes, possibly more forgiving to aging eyes? I had not felt this way until just recently, when I had started having some problem in my one eye, due to fluid loss, and an increase in floaters. It...
