A week ago tonight my son, Ethan, could have had some very serious skull injuries.  I believe the only reason he avoided a skull fracture and a concussion was because he was wearing rec specs.
My sons were taking turns pitching to each other.  Ethan was taking his turn catching, and missed a 60 mph fast ball just above his catcher's mitt.  The ball hit him square between the eyes--directly on the bridge of his rec specs.  From all that my husband could see it appeared as if the glasses had shattered right off of his face.  Naturally, my husband was worried about the cut between his eye brows and his massively bloody nose and took him to the ER, while I went out to the back yard to pick up what I imagined to be shattered pieces of glasses & lenses in the backyard before it got dark.
When I went back to where Ethan had been crouching down to catch, I found the frames lying in the grass perfectly intact with only a tiny scratch to show from the fast ball, and the lenses, without a scratch on them, had merely popped right out.  Not a thing was broken.  I am convinced that the nosepiece padding on the rec specs absorbed most of the blow, and saved him from being seriously injured.  Clearly these glasses were designed with the utmost safety in mind.
Ethan has had poor vision his whole life, but has played football, basketball, and baseball since he was 5 years old.  He has had his rec specs for 4 years, and has worn them for every one of those sports.  Luckily we have never had to experience an injury of this magnitude till now, and I have been encouraging all parents who have kids who need to wear glasses for sports to get rec specs. 
I would endorse this product 24 hours a day, 7 days a week....! 
Thank you!!
