Even though I have 2 bad experiences, I will probably still try it one more time. Mainly because the lenses are more than 50% less than outside optical stores. Yes, I'm gluttoning for punishment.
Here's my experience. A few years ago, I bought 2 complete pairs of eyeglasses with progressive lenses. It came with Anti_reflective and Anti-Scratch coating. The only difference is the 2nd pair was not photochromatic / transition lenses.
I wore the 1st pair for a couple of years. Then the temple hinge broke. I had never had any of my past glasses break here. This pair was a Zegna brand frame which I paid a premium of $120.
Then, I wore the 2nd pair. After only 9 months of gentle washing with only water, the Anti-Reflective and Anti-Scratch started peeling. This has never happened to my previous glasses. When I went to Costco to ask about this, the optician said it was like this. NOTE: this did not happen to the 1st pair.
The other thing I am annoyed about is the fact that the lenses on the two pairs were different in quality even though I PAID THE SAME PRICE. The optometrist showed me on the computer that my 1st one was Hi-index 1.65 or 1.67 and the 2nd was only a 1.59 / polycarbonate. That's why the 2nd felt heavier. Because it was! At the time I purchased these 2 glasses, there was only 1 price for thinner lens ($130). They should be the same. In 2020, the polycarbonate is $130 and the Hi-Index 1.67 is $160 for progressives.
