I got these for my niece and she loves them. She is two and on the tiny side so these are perfect! She's not a huge fan of the strap but i think it will be helpful at the park or whatnot. They have great polarized lenses which are great protection! I love that they come with a little sleeve too.

Note! These are not for older kids. I would consider these toddler sunglasses, which I saw later in the description. I did find a two year old who immediately put them through a stress test. They fit really well and have a strap on the back to help them stay on, but it's not so restrictive that the kid can't remove them. They didn't break when they were stepped on or when the ear pieces were pulled outward.
