Understanding Blue Light Eyeglasses & How to Protect Your Eyes
In our digital age, we’re constantly surrounded by screens—whether it’s our smartphones, computers, tablets, or TVs. While these devices have undoubtedly made our lives more convenient, they also expose our eyes to significant amounts of blue light. At La Mesa Family Optical, your local optician in La Mesa, CA, we believe it’s important to understand blue light and how to protect your eyes from its potential effects.
What is Blue Light?
Blue light is a high-energy, short-wavelength light that is part of the visible light spectrum. It’s naturally present in sunlight and plays a vital role in regulating our circadian rhythm, which is our body’s natural sleep-wake cycle. However, artificial sources of blue light, such as LED lights and digital screens, have become pervasive in our daily lives.
Potential Effects of Blue Light Exposure
Digital Eye Strain
Prolonged exposure to blue light from screens can cause digital eye strain, leading to symptoms like headaches, blurred vision, and dry eyes. This condition, also known as computer vision syndrome, affects many who spend long hours in front of digital devices.
Sleep Disruption
Excessive blue light exposure, especially before bedtime, can interfere with your circadian rhythm. It suppresses the production of melatonin, the hormone responsible for regulating sleep, making it harder to fall asleep and potentially leading to poor sleep quality.
Long-term Eye Health
While more research is needed, some studies suggest that long-term exposure to high levels of blue light may contribute to retinal damage and increase the risk of age-related macular degeneration.
How to Protect Your Eyes from Blue Light
Wear Blue Light Blocking Eyeglasses
At La Mesa Family Optical, we offer a variety of blue light-blocking eyeglasses that can reduce your exposure to harmful blue light. These glasses are available with or without prescription eyeglasses, making them suitable for everyone.
Follow the 20-20-20 Rule
To alleviate digital eye strain, practice the 20-20-20 rule. Every 20 minutes, take a 20-second break and look at something 20 feet away. This simple exercise can help reduce eye strain and fatigue.
Adjust Your Environment
Reduce overhead lighting to minimize glare on your screen and adjust the brightness and contrast settings on your devices to comfortable levels. Position your screen so that you’re looking slightly downward at it.
Limit Screen Time Before Bed
Try to avoid using digital devices for at least an hour before bedtime. This helps minimize blue light exposure and allows your body to produce melatonin naturally, promoting better sleep.
