Common sense of using sunglasses

Improper wearing of sunglasses can lead to eye diseases, and it is not necessary to wear sunglasses on cloudy days or in dark indoor conditions. Some people wear sunglasses regardless of the intensity of sunlight, even at dusk, in the evening, and when watching movies or TV. This inevitably increases the burden of eye adjustment, causing tension and fatigue in the eye muscles, leading to vision loss, blurred vision, and in severe cases, symptoms such as dizziness and blurred vision. Babies, children, and others whose visual system is not yet fully developed should not wear sunglasses. Except for glass sunglasses, the wear resistance of other sunglasses lens materials is not high. Users should regularly pay attention to the surface condition of the sunglasses and replace them in a timely manner when wear affects clarity.
