Many people spend hours on computers, tablets, and smartphones, often late into the evening. But did you know that blue light from screens can interfere with your sleep? Understanding how it affects your body can help you protect both your eyes and your sleep quality.
How Blue Light Impacts Sleep
Blue light is a high-energy visible (HEV) light emitted by digital devices, LED lighting, and the sun. Exposure to blue light in the evening can:
- Suppress melatonin production, the hormone that signals your body it’s time to sleep
- Delay sleep onset and reduce overall sleep quality
- Disrupt your natural circadian rhythm
Even normal evening screen use can make it harder to fall asleep, leaving you tired and less alert the next day.
Can Blue Light Glasses Help?
Yes. Blue light glasses may reduce some of the effects of evening screen time. Wearing them 2–3 hours before bed can:
- Reduce melatonin suppression
- Improve sleep onset and quality
- Reduce eye strain and discomfort from prolonged screen use
