I bought these frames to put prescription lenses into them. Ive used these frames before but I bought them from a mall kiosk for like $20 so Im glad they are half the price on Amazon. I used Lensabl for my prescription lenses - when you pay, you can use your amazon account and I think thats a neat feature (google it, they're great for putting in prescriptions lenses for cheap if you want to use your own frames, you can even use sunglasses frames that you like). The total cost to use lensabl for me was $65 since they were offering a 15% discount on your first order but their cheapest option without the discount is $77 which is a steal! I was going to take these frames to Walmart or LensCrafters to have them put in prescription lenses but they were giving me estimates upwards of $120 bc they charge a fitting fee and said my eye sight is above 4x so I have to get special lenses but Lensabl didn't charge me extra for my worse than average eyesight, which is nice. They also donate a percentage of whatever you spend with them to children within low income families to get free eye exams and glasses so I think its a great cause to support. As far as these frames go - I think they're sturdy. My old pair lasted me like 3 years but Im also pretty careful and only wear them at night since I have contacts to wear during the day. When they finally broke it wasn't a big deal bc it was the arm that broke off due to a lost screw and I guess I could have replaced the screw but I needed new prescriptions anyways so the actual frames never broke but if I looked closely it did have small cracks but prob bc my eyesight is so bad that the lenses put pressure on the frame however Im impressed they never cracked all the way through or peeled or anything - the lenses always stayed put and never popped out. I used to have the green frames and they are really cool but I wanted purple this time. I was hesitant at first to buy the purple ones because the picture they have is kind of a burgundy color instead and I was worried it wouldnt be obvious that the glasses are purple. However Ive posted pictures comparing the actual frames to the picture and you can see that it is definitely more of a purple. So Im very happy about this purchase!  If you want to wear these glasses with the clear lenses that it comes with, I would not recommend that because the quality of the clear lenses are kind of hazy and when Amazon shipped these glasses to me they did not put it in a box but rather a packaging envelope and so the clear lenses were scratched up a tiny bit but I don't care because Im getting my prescription lenses into them! And no I was not paid or given any incentives to write a review about this seller/product/lensabl.
