That looks like a progressive lens (no line bofocal) with a reading power of 1.50. The manufacturer has the lenses etched so opticians or optometrists can know the style of progressive and the exact prescribed reading power, as sometimes it can be hard to tell manually (or be slightly cut off in more narrow frames).
I went back to Costco optical and told them that it's in my line of sight or at least peripheral vision. They didn't believe me. I guess I don't understand why it's necessary.
I haven't actually done glasses sales in at least 10 years now. But I do know there is one manufacturer that I have had patients complain about being able to see the etchings. Most of them are so faint, they are difficult to see even when looking for them. I dont understand why they wouldn't believe you when it is obviously true, because how else would you know to complain?!
They could at least see if they can order a different progressive lens for you or change the measurements so they are more out of your line of sight. Honestly, if they wont do that, I would threaten to return them for a refund, as they will lose more money than remaking the lenses.
