My optics on my rifles are all Leupold. Love them and never had an issue. My binoculars are Vortex only because of them being on sale and cheaper than the Nikon I was looking at.
I need night scopes now though. Even with the bigger scope my eyes are getting old and cant see early morning.
As our eyes age, the pupils lose the ability to dilate. When you're young 7-8 mm is possible. At 50+ perhaps < 5 mm.
Why does this matter? Because the exit pupil of the optics = the entrance pupil of the eye. That is to say if you have 10x56 optics, their exit pupil is 5.6 mm. If your eye pupil does not dilate to more than 4 mm, you're wasting money on expensive optics and you'd be OK with 10x40 optics.
Or: You cannot compensate for aging eyes by buying "brighter" optics.
