Buy Glasses For Kids - Proper Lens
The size of the lens mainly determines the size of the eyeglasses. The outer edge of the rim of the lens should be on the outer edge of the orbital bone. If it is larger than the face, the rim of the lens frame will be too big. If the lens is only as big as the eye, the frame can easily deform. Resin and hard lenses should be considered first because glass lenses are fragile and easy to damage children's eyes. Resin lens mainly needs the accuracy of the axis of scattered light. The matched luminosity must be accurate. There are no scratches, no bubbles, and no impurities on the lenses. The degree of the lens selected for the child must conform to the quality testing standards promulgated by the state, and the error of the diopter should be within the range of the requirements of the national standard.

The soft feature of plastic glasses makes them susceptible to scratching from a sharp object and why scratch-resistant coating is applied to form an additional protective layer. Plastic lenses do not provide ultraviolet protection.
