In order to ensure the safety of the prescription eyeglasses I buy for your kids, I always buy the prescription eyeglasses with the polycarbonate lenses. The polycarbonate lenses are much more durable than the normal ones, and also they are very light, wearing them can be very comfortable. This kind of lenses can still be the same as usual even when they fall onto the ground. Thus ensure that the broken lenses won’t hurt you’re my kid’s eyes.
