Anecdata being what it is the last non-Zenni glasses I bought were from Lenscrafters and had a blurry spot they refused to acknowledge or fix and I lived with it for years.
Zenni glasses are so cheap if you get a bad pair you just buy another.
Can't comment on weight differences and so on. I haven't had a problem with the weight of the lenses w/my prescription. My wife has a very strong prescription and purchases the highest index option and she hasn't noticed a difference. Index is index and material is material so unless you are comparing apples to oranges is it actually possible for them to differ?
Regarding clarity. I get more mileage from cleaning my glasses with dish soap then I do from the optical qualities of the lens. Maybe mine get dirty faster then most.
