No idea about dads but I wear these and they are great. I lose them all the time and they’re cheap enough that I don’t mind, and they also provide some impact protection.

Something I learned is that I stopped losing my sunglasses when they cost a fair amount. When I purchase cheap ones and don’t give a shit, they break or are lost, and end up costing more. When I got nicer ones I never lost or broke them. Just a one time payment.
Now I wear prescription glasses (I did wear contacts), so they’re both expensive and I can’t live without them. Obviously losing or breaking them isn’t something that happens now.
I also thought that until I lost my pair of very nice Costa Mesas. Luckily I didn’t pay anywhere close to retail, but still, losing a $50 pair fucking hurt.
