I did some more research. This website lists all of the Clarion IOL offerings:

A summary. My nonprofessional comments in square brackets.

Clareon® Monofocal
Provides clear distance vision. You may need glasses for clear near and intermediate vision.
[covered by many insurance policies]

Clareon® Toric
Provides clear distance vision while correcting astigmatism. You may need glasses for clear near and intermediate vision.

Clareon® Vivity®
Allows you to see clearly at far and intermediate distances. You may require glasses for reading small print.
[bifocal - maybe fainter/fewer halos than trifocals]

Clareon® PanOptix®
The first trifocal lens available in the United States. Enjoy a full range of vision and exceptional clarity, and reduce your need for glasses.
[trifocal]

Clareon® PanOptix® Pro
The next generation of PanOptix innovation for a full range of vision and less reliance on glasses. Take vision to the power of Pro.
[trifocal, said to correct astigmatism too]

Besides significant cost, I suspect that the bifocal and trifocal offerings will reduce contrast to some degree.

Some bifocal and trifocal IOLs cause visual halos for nighttime driving.

Good research there Pipe, I'm sure there are better versions coming out all the time.

Back when the doc was going over my options he said I had three choices.

1)Monofocal which he described just as your description, see far but need readers.

2)I forget the name but multi powered that improved mid and short distance (maybe PanOptics). Side effect is may slightly notice the "rings" and some report slight glare from say headlights.

3)Vivity, similar to above, may need readers for the smallest print. But rather than "focus rings" the transition is more gradual so you don't notice them and no flares from headlights.

Since one problem I was starting to have was poor night vision and headlight glare was really bothersome, and I preferred to do away with readers if possible, I chose #3.

In regards to halo’s at night it was something I was worried about because I did a lot of driving in the dark. Post procedure for a couple months it was bothersome but not a problem. Not a problem for me anyway, but ymmv. Everything I had read was that it goes away after a time so I wasn’t too concerned. It has gone away to a point that I don’t notice it anymore but if I look for it I can see it. Halo isn’t really accurate to me, more like concentric rings around lights that converge into the light source as you get closer. I used to look at lights ( not really recommended ) while driving to try and count the rings.

Thinking about it halo might be accurate with only one correction in the lens. The Panoptix has several rings thus the multiple rings around lights. In any case, what may seem bad at first does go away for all or most of us.
