Just a note. They (eye Dr. staff) told me it would take a long time to get used to the progressive lenses, and it did. Took a year and a half. But now they work great. Recently I needed new lenses and I opted for the transitions/extra-active lenses. They darken fairly fast and look dark grey in bright sunlight and black when snow is on the ground. However, you don't realize that looking through them. I did get a pair of clip-ons in amber for low light days and mornings and evenings. They are great for fishing and hunting but must be removed when the sun is up, too bright!
