Night Lights is a common sight in our bed room, balcony and even corridor. They are small and colorful when we turn it on in the dark. Night Lights bring us not only light but also a warm feeling. Every time I look at the lovely pattern on it, I cant help but smile. Moreover, during the day time, the untiring night lights always seem to be ready to bring us a romantic atmosphere at night. From the perspective of science, night lights can effectively reduce eye strain. Low-light night lights can emit a soft white light, which can help us to reduce the light-induced pupil constriction. By doing so, we can reduce eye fatigue caused by screening and artificial lighting. In addition to its protective function, night lights can also create a pleasant atmosphere. We can put the night light of different shapes in the corridor, the entrance of the bedroom, the window, and so on. The colorful, lovely night lights always make the room look more dreamy and romantic. At the end of the day, night lights are really a warm and sweet thing, whether it is for eyesight protection or just for decoration.
