I know this is correct since I have -5.5 Diopters and when rolling the focus all the way to the right, I have what seems like a millimeter left. Interestingly and just FYI, the 10x42 EL has a full -8 Diopters at infinity value. If you are above 6D, this is important. If my vision gets any worse, I will have to upgrade from 8.5x42 EL to 10x42 EL , though at this point I am mostly interested in Zeiss.I much prefer to have the binos correct the vision for me, versus eyeglasses. There is just no need for eyeglasses when you two fabulous options available:  (1) use contact lenses - you should try  the daily ones, they are completely transparent, this is not the 70's or the 90's anymore, and cheap or (2)  don't use anything and let binos correct it for you. I have no astigmatism, have identical myopia and thus EL 8.5x42 works well for me.  If you have either astigmatism, this won't work and if you have different diopter values, this won't work either - very well. You can set the diopter wheel to whatever value but then once you put on eyeglasses or contacts,  you will have to reset the wheel back to zero - not convenient. Anyway, if I am wearing eyeglasses, I take them off, if I am wearing contacts, I don't adjust the focus all the way to infinity and that works very well either. Optically, my favorite has been Leica in the 8x42 configuration but they are unable to update the D at infinity value beyond -4, which is inexplicable and inadequate. I could only use them with eyewear and their ER was not that great.  Swaro is barely enough but I think my next device will be by Zeiss more likely 8x42 SF. Would be great to find out what their precise value is of D at infinity. I've also come to realize I cannot handle more than 8 to 8.5 power comfortably, so if they do come out with 50mm lenses, I will likely stick either with 8x42 or even 8x50, both great options.</blockquote>
