I don't think it does wonders for near/far focusing problems caused by aging. You still end up with what is the equivalent of a fixed focus camera lens but what IS in focus is much better. Sometimes they do one eye to favor near and the other to favor far and let your brain make up the difference.
There are a few techniques that are being used to permit both near and vision. One approach, in use for many years, called monovision, sets one eye to focus on distance, and the other on near. It works reasonably well for many people, but reduced depth perception, and some people have trouble adapting. Newer approaches include two types of corneal implants that provide near vision without sacrificing distance. Another approach attempts to set the eye to have two fields of focus.
i have perfet eyes, so i dont need it! :wiggle:
I would love to try it but no Money!!!
I would have a problem with that depth perception part and I figured it would mess with that. Twice a day I park next to a telephone pole where I can slide up so my right side mirror is within 2 inches of it consistently. I occasionally meet tractor trailers in a narrow spot where there is parking on both sides of the road with my snow plow on with no problems but most others even with today's tiny cars stop and wait for the truck to come through. I would not want to lose that ability. I have enjoyed that kind of depth perception for over 60 years and I thoroughly enjoy it.
