Wow. These are my first &#34;blue-blocker, fit-over glasses. I decided to go cheap.<br /><br />I'm a careful person and I take care of my things. I had read the other 1-star reviews, so I knew I would need to be careful. And I was.<br /><br />For $17.97 I thought I could get more use out of these than I did. But I didn't make it through even 5 or 6 uses -- over 10 days or so -- before the left-side lens frame broke about 1 inch below the nose-fulcrum.<br /><br />Wow. Poor engineering, poor quality, poor materials. In my estimation, these glasses would be properly priced at $1.79 not $17.97.
