DID YOU KNOW?
Blue light at night can cause depression, but during the day, it can actually boost alertness and mood. [1]
KNOW THE RISK
- Blue light from electronics is linked to problems with sleep, eye strain, and even long-term vision risks. [1]
- It has a shorter wavelength and higher energy than other visible light, making it more likely to reach deeper into the eye and affect the retina. [1]
- Overexposure — especially before bedtime — can suppress melatonin production and interfere with sleep cycles, leading to fatigue, poor focus, and increased health risks over time. [1]
MITIGATE THE RISK
1. Use Blue-Light Filters
- Apply screen filters or wear glasses that block blue light. Most smartphones and computers now include a night shift or blue-light reduction mode. [1]
2. Power Down Before Bed
- Avoid screen use for at least 3 hours before sleeping to allow your brain’s natural sleep hormones to reset. [1]
3. Limit Screen Time for Children
- Children’s eyes are more sensitive to blue light, and excessive screen time can increase risks of digital eye strain, behavioral changes, and disrupted sleep. [1]
VISION AND SLEEP HEALTH REMINDER
Not all light is created equal. Use screens wisely, filter blue light, and give your eyes and brain time to rest — especially before bed. Small changes can lead to clearer vision and better sleep.
