I don't think any person can "tell" you what to get. Nor can they make sweeping statements like "Varifocals (which I assume is another term for progressive lenses) should be banned for pilots".
Glasses are such a personal thing that it is presumptuous for someone to stipulate to another what is, or is not acceptable.
I tried bi-focals and hated the bloody things. I've used progressives now for about 10 years or so, never had any problems with them, and for me, I reckon they're the greatest thing since sliced bread.
