Blue light is a type of light that is emitted from the sun, electronic devices, and fluorescent lights. It is a short-wavelength light that can penetrate deep into the eyes and disrupt the body’s natural sleep-wake cycle.
There is growing research that suggests that blue light exposure can have a number of negative effects on our health, including:
- Eye strain
- Headaches
- Difficulty sleeping
- Increased risk of macular degeneration
- Increased risk of cancer
Do blue light glasses work?

Blue light glasses work by filtering out blue light from the light that reaches the eyes. This can help to reduce eye strain, headaches, and difficulty sleeping. However, blue light glasses do not block all blue light, so they may not be effective for everyone.
