These are my second pair of lenses from Jacob. My first were single vision sunglasses. Without a doubt, the best optics and sun filtering glasses I’ve ever owned and I’m in my 70’s and worked outdoors for a living. This second pair are clear progressives. I generally wear bifocals and was skeptical about the adjustment. Jacob led me in that direction and I’m happy he did. That’s what makes this company so special. They are not only experts, they become your friends and earn your trust. The quick turnaround time and ease of shipping are just icing on the cake. Thanks again Jacob!
