Some people choose to wear blue light-filtering glasses in the evening, particularly when using screens, to reduce blue light exposure. Exposure to blue light in the evening may stimulate melanopsin-containing retinal cells, signaling the brain to remain alert and thereby making it more difficult to initiate sleep.1Some individuals may opt to wear blue light–filtering glasses during evening screen use to mitigate this effect.2 However, current evidence is limited, and further research still needs to be studied. 

If you’re experiencing ongoing sleep difficulties, it's best to speak with a healthcare professional or sleep specialist for guidance tailored to your needs.
