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.

Why do spectacle lenses fog up?
The fog on the surface of the lens is essentially related to the saturation pressure and water vapor liquefaction. The air is full of water molecules, which are constantly doing irregular movements. When there is no temperature difference, water molecules keep hitting the surface of the lens and will keep bouncing off. The lower the temperature, the slower the speed of movement. Therefore, when water molecules hit the cold lens from the hot air, on the one hand, they move too slowly to fly out in time. On the other hand, because of the relatively low temperature of the lens itself and its vicinity, the water vapor will liquefy. As a result, more and more water will accumulate on the lens and form small droplets, eventually forming a foggy layer. As the lens heats up, the mist evaporates back into the air, and the fog disappears.
