Common sense
Wearing sunglasses improperly can lead to eye diseases. There is no need to wear sunglasses in situations with dim light, such as on overcast days or indoors. Some people wear sunglasses regardless of the strength of the sunlight, even in twilight, dusk, or while watching movies or TV. This will inevitably increase the burden on the eye's adjustment, cause blurred vision, and in severe cases, symptoms such as dizziness and eye strain may occur. Babies and children with an immature visual system should not wear sunglasses. In addition to glass sunglasses, other sunglasses have low abrasion resistance, and users should pay attention to the condition of the sunglasses surface frequently. When wear and tear affects clarity, it should be replaced in time.
