How Blue Light Affects Your Eyes
In today’s digital world, we spend hours staring at screens—whether it’s a computer, smartphone, tablet, or television. While technology keeps us connected, it also exposes our eyes to blue light, which can cause digital eye strain and disrupt sleep patterns.
At L'Optique Optometry in Rochester Hills, we help patients protect their eyes from blue light exposure with blue light glasses and expert recommendations.
What Is Blue Light?
Blue light is a high-energy visible (HEV) light emitted by the sun, LED lights, and digital screens. While natural blue light from the sun regulates our sleep cycle and boosts alertness, too much artificial blue light, especially at night can lead to:
Digital Eye Strain – Eye fatigue, dryness, and discomfort from prolonged screen use.
Sleep Disruptions – Blue light suppresses melatonin production, making it harder to fall asleep.
Increased Risk of Eye Damage – Long-term exposure may contribute to retinal stress and increase the risk of macular degeneration.
Signs of Digital Eye Strain (Computer Vision Syndrome)
If you spend hours on digital devices and experience any of these symptoms, you may have computer vision syndrome (CVS):
✔ Dry, irritated, or watery eyes ✔ Headaches and eye fatigue ✔ Blurred or double vision ✔ Difficulty focusing on screens ✔ Neck and shoulder pain from poor posture
The good news? You can protect your eyes from blue light with simple adjustments and proper eyewear.
How to Reduce Blue Light Exposure & Eye Strain
1. Wear Blue Light Glasses
Blue light-blocking glasses help filter HEV light, reducing strain and improving comfort during screen use. At L'Optique Optometry, we offer a wide selection of prescription and non-prescription blue light glasses tailored to your needs.
2. Follow the 20-20-20 Rule
Every 20 minutes, take a 20-second break and look at something 20 feet away. This simple habit reduces eye strain and refreshes your vision.
3. Adjust Your Screen Settings
- Enable Night Mode or Blue Light Filters on your phone, tablet, and computer.
- Lower Screen Brightness to match room lighting conditions.
4. Use Proper Lighting
Avoid harsh overhead lighting and position screens to minimize glare from windows or lamps.
5. Blink More & Stay Hydrated
When staring at screens, we blink less, leading to dry eyes. Make a conscious effort to blink frequently and use artificial tears if needed.
6. Limit Screen Time Before Bed
Reduce screen exposure 1-2 hours before bedtime to allow your body to produce melatonin naturally for better sleep.
