These are really inexpensive and are good for kids that will abuse or lose them. My kids say they are comfortable and my older son who is nine can even wear them over his regular glasses. For the price I am very satisfied.
Pros: Comfortable for my seven & nine year olds.
Cons: Plastic lenses can be scratched relatively easily.
