It’s not the shape, it’s just the transitions themselves. Aesthetically, sunglasses have a handful of popular styles. Whatever frames you have for your regular vision correction, most likely aren’t one of those styles.
I’ve worn glasses my entire adult life and I had to get rid of them because being half blind every time I transition from outside to inside was interfering with my job.
It wouldn’t surprise me if they didn’t hold up more than a couple years if you were using them 40+ hours a week on commercial jobs for years on end, but for weekend home use? I’ve had my basic drill for like idk 10 years now and it still works as good as the day I bought it. I have a handful of Ryobi tools and recently picked up the bottom tier Ryobi 40v mower and have been nothing but impressed. I’ve done a lot of mowing of tall, wet grass the last few weeks and the thing just works.
Ryobi. I have a bunch of 18v tools and a 40v lawn mower and they’ve all been great. I could afford better I suppose but so far I haven’t had any reason to switch.
