My 2 year old has used Miraflex glasses for almost a year. He now has 2 pair and as a parent, I couldn't be happier with them. They lose their shape easily but as long as you put the band around them at night it shouldn't be a problem. I think these frames are indestructible and perfect for toddlers!
Great frames for my 2 year old! I love that there are no hinges to come loose or break and that the material is so flexible (think Gumby). They're easy to put on and stay on well with the removable and adjustable elastic strap. These frames have survived tossing tantrums, though the nose bridge does have a few scratches as a result. Despite being a chunky frame, my son gets constant compliments on his "cool glasses."
