I have used the crizal lens and found the following cons of using these lens :
• They can look dirty due to the clearness of the lenses.Although anti-reflective coatings are really not any dirtier than a regular pair of glasses, they're more noticeable because there isn't any glare to hide the dirt.
• As a result you may have to clean your lenses more frequently, which can especially be the case for some of the lower-cost AR coatings
• Generally they aren't recommended for reading glasses that rest on the low bridge of the nose. If you do spend a considerable amount of time using a tablet, just be sure you read in conditions that provide adequate light.
