Why mono vision? Once you hit 40+ you'll be increasingly unable to see close up and you'll need bifocals. By 50, you can't read a book without bifocals. Monovision largely correct for both close and far vision, eliminating any need for bifocal glasses.
I considered Lasik, but my eye doctor advised me that Lasik can only correct for the distance vision and get me to 20/20, but I would still have to wear glasses for close vision....like reading my Garmin watch or seeing the readings on my bike power/cadence device.

I am in that 50+ age (52) where I will need to get bifocals SOON :)
I have been wearing glasses only for the past 10+ years, and wore contacts mostly prior to that.
I am interested in the laser procedure, but if not a candidate, or if I chicken out, I think these mono-vision lenses sound like a great compromise.
Can you tell me if there are side effects of having two differing lenses/corrections? I wonder about dizziness etc. Do they also correct for astigmatism?
Additionally, I wanted to add / ask that I was under the impression that laser procedures are now possible to correct for mono-vision, as your contacts seem to do.
thanks
There are no "side effects" that I'm aware of. I've worn soft contact lenses for 30+ years. As my vision began to change in my late 40's I was increasing becoming a guy who had to always carry bifocal glasses. I went to my eye doc thinking Lasik. He explained that Lasik wouldn't solve my close vision problem. They could correct my vision, but I would continue to lose close vision. He told me I would see perfectly for distance, but bifocals would be required for close vision.
As I understand it, the mono vision essentially corrects one eye for distance, the other for close vision. It takes a couple of days, but somehow your brain is wired to figure out which eye to use to process the visual info it sees, using the appropriate eye to give you 20/20 vision be the image close or far. I never experienced any kind of dizziness or any other side effect. The only downside is my vision is not quite as precise as if I only correct for distance or if I wear bifocals. Far distant horizons are not quite a sharp as with glasses. I still struggle a bit reading menu's in a dark restaurant or reading my Garmin 500 from the aero position when my face is 10 inches or so from the device. I'm told that eye dryness can come with age, but I haven't experienced it yet. For now, I'm completely happy with my soft contact lenses and the results I get with mono vision....no bifocals, unlike many of my older, Lasik corrected, bifocal wearing friends.
