Then how does this explain my being blurred at all distances? I was not always blurred at all distances, it stated with the 'age' related need for a pair of reading glasses. I'm 56 and see blurred at all distances. Had a cataract removed from my left eye about 8 years ago. The one in the right is on a scale from 1-100 a 15, a long way from removal. I wear tri-focals which need changing every year as my reader needs strengthening by a quarter power.
If you point a diverged laser beam at a wall and look at it, what do you see? As you move your head, how does what you see change?
Your prescription has probably gone up over time (usually becoming more farsighted/less nearsighted in the 50's) and the lens hazes and stiffens over time due to UV light absorption (of course, your intraocular lens implant does not "flex" like your natural lens).
The midrange focusing ability changes usually around the mid-fifties which is when most people need to get the trifocal or progressive multifocal to try to help at that distance. It's best if patients can start in a progressive in the beginning and they will never notice those midrange troubles. I usually prescribe the Ovation brand of progressives or one of the other newer brands for my patients. The el-cheapo progressives many opticals advertise are based on 20 year old lens designs that are not nearly as clear and smooth as the newer designs. As with everything else, you get what you pay for.
