KANASTAL Heart Shaped Sunglasses for Women Men, Oversized Trendy Love Shaped Retro Sunglasses UV400 Vintage Cute Eyewear Valentine's Day

These clip on sunglasses are extremely sturdy and reliable. I have had other clip ons over the years, that are too fragile. Especially, the very thin plastic link between the plastic lenses. The Kanastal clip on link is solid and won't break like the aforementioned. And to be able to flip up the sun glasses after going into a store or public car garage, is a lot more convenient than having to take them off in low lighting each time. Couldn't be happier with the product. Well worth the price.
