Thanks for the replies, I would just like to add my vision was good before cataract & better after...the surgery & the YAG surgery were done to alleviate glare so probably not the glasses RX. I will look into other causes you mentioned with another doctor later in year I am recovering from ptosis lift. Also the Zeiss individual.
The IOL can move out of position, the membrane can cloud backover, there can be new problems like corneal or macular disease. The glasses RX can change.

What would cause Xaminer to develop a glare problem after a year with Crystalens?
Nothing dramatic: anti-reflect helps ;some but others don't like it. There is a new type of aspheric abberation reducing glasses, extra cost different brands one is "Zeiss Individual".
