I got it (I hope). If I had no long distance needs, the highest prescription strength I may need up until age 65 is about 2.75 -3.00.. Since I have long distance lenses, even if they are minimal, it means I will likely exceed 3.00 before age 65. Particularly, since I am already at 2.75 at age 47. Is this correct?
(The twenty plus lens are used for those who see exceptionally well far away, which eventually creates a close up issue requiring strong lenses)
Hope I understood this all correctly.
Thanks for the mini education class on aging eyes. Stay safe
