I have several but similar problem I am 73 Last year I ordered a pair of Bushnell online, 10x50 insta focus, they are a little bigger than my US Camel 8x40 which zI like The insta focus are amazing just put them to your face and look, no fiddling with adjustment - 300ft at 1000ydsWhen I looked at binos I decided that the 10x42 ELs were too heavy to lug around the mountains. In the end I went with the Swarovski 10x32 EL and they are fantastic and I have really enjoyed using them for the last 5 years. I have compared then side by side with my cousins 10x42 ELs and I don't feel that I am missing anything in low light conditions, maybe 10 minutes at the most. Just like you I am getting very close to the big 60.
The US Camel - 430ft at 1000yds
To my old eyes both are great cheap binos
Just my 2 pence worth
