I've worn glasses since about 1950, and varifocals for a fair proportion of that. I'm delighted with them The critical bit with varifocals is to get them made up to suit what you do. There are a lot of "options", apparently - or so my optician tells me.
I fly with mine, and have no problems.
The only catch is: if I nod at you, I'm not agreeing: just getting you in focus.
