This is the second time I've used the lens replacement service. Both have been well executed. My prescription is fairly strong, and I'm always a bit worried the lense clarity or alignment will be "off" and I'll experience various brain-corfusing distortions. But in both cases, lensabl got it right. I ordered the highest-index lenses, had them roll and polish, and all was done perfectly. I hope you have an equally good experience.
