Because the harmful light waves in ultraviolet rays can damage the human cornea, lens, and retina, if they are exposed to strong sunlight for a long time, they are easily damaged. Moreover, children's eyeballs are still in the stage of growth and development, and have not stabilized yet, and they will suffer more damage. Therefore, the anti-ultraviolet function of the sun needs to be taken seriously. The choice of lens needs to choose those with wear resistance and drop resistance, such as resin lens material and PC material, which are good and resistant to damage.
