I got a pair of prescription glasses about 2 weeks ago and noticed this clear "S" shape only on the right lens when I hold it in the light. I can also notice the blurriness when I have the glasses on. I have a short video of it. You can see it around the middle part of the lens. Is this some kind of defect?\n\n[MEDIA=youtube]dlAZ9oYtRBc[/MEDIA]\n\nI took it back to Walmart's Vision Center where I got it from and the representative there said they couldn't see what I was talking about because it's a little difficult to see it in the store light. They want me to bring it back when their manager is there to inspect it.
