We spend a lot of time in front of digital screens these days: A recent study reported that Americans spend around five hours a day staring at their phone, and that figure doesn’t even account for computer and tablet use.
Mobile phones, computers, and televisions emit blue light, and many worry about its effect on the eyes. At Austin Eye Clinic, our renowned ophthalmology and optometry specialists understand this concern, and we’re glad you’re proactively thinking about your eye health.
Today’s blog explores blue light: What it is, how it can affect your vision, and how to manage exposure.
What Is Blue Light?
Blue light is a type of high-energy visible light that comes from digital screens and LED lighting. It’s also present in sunlight. Its short wavelength means it has more concentrated energy than other colors in the light spectrum.
Some studies suggest that excessive exposure to this powerful light may cause vision and general health problems.
How Blue Light Affects Your Vision and Health
Many studies are currently investigating the effects of blue light on the human body. Previous studies have shown some worrying trends among people who spend a lot of time in front of screens, including:
- Temporary blurry vision
- Increased eye strain during long periods of screen time
- Dry eyes, as most people blink less when staring at screens
- Disrupted sleep patterns when using devices late at night
These problems don’t usually lead to permanent damage, but they can definitely make your day-to-day activities less comfortable. Simple adjustments can reduce the negative effects and help you maintain healthy eyes.
Simple Steps to Protect Your Eyes
You can take a few easy measures to lessen the impact of blue light on your vision.
- The 20-20-20 Rule: Every 20 minutes, take a 20-second break and look at something 20 feet away.
- Screen Brightness: Reduce the brightness of your screens and use night mode if you use your phone in the dark.
- Adjust Room Lighting: Change the lighting in your room to reduce glare and eye strain.
- Manage Sun Exposure: The sun is also a source of blue light, so it’s important to wear sunscreen and sunglasses to protect yourself outdoors.
When added to your daily routine, these small steps help keep your eyes comfortable while you enjoy an active lifestyle and embrace the benefits of modern technology.
