As screen time continues to rise in both work and everyday life, blue light has become an important topic in modern eye care. Blue light is a high-energy visible light emitted by digital devices and artificial lighting, and prolonged exposure may contribute to eye strain and visual discomfort. During comprehensive eye exams in Buckhead, our doctors at Family Eye Care Center of Atlanta help patients recognize the effects of blue light and explore personalized solutions for long-term eye health.
 

What Is Blue Light?

Blue light is part of the visible light spectrum - the light we can see with our eyes. It has a shorter wavelength and higher energy than other visible light colors. Blue light comes from both natural and artificial sources:

• Natural source: The sun (the largest source of blue light)
• Artificial sources: Digital screens, LED lighting, fluorescent lighting, and televisions

During daylight hours, blue light helps regulate our circadian rhythm, boost alertness, and improve mood. However, problems can arise when we’re exposed to high levels of artificial blue light for extended periods. Excessive or prolonged exposure to blue light may contribute to several eye-related and health concerns.
 

Digital Eye Strain

One of the most common issues we see during eye exams in Buckhead is digital eye strain, also called computer vision syndrome. Symptoms often include:

• Eye fatigue
• Dry or irritated eyes
• Headaches
• Blurred vision
• Neck and shoulder discomfort

Blue light scatters more easily than other visible light, making it harder for the eyes to focus. This forces your eyes to work harder, especially during long periods of screen use.

Sleep Disruption

Blue light plays a major role in regulating sleep. Evening exposure - especially from phones, tablets, and laptops - can suppress melatonin production, the hormone that helps you fall asleep. Poor sleep doesn’t just affect energy levels; it can also impact long-term eye health and overall wellness.
 

How Can You Protect Your Eyes from Blue Light?

The good news is that there are effective ways to reduce blue light exposure without giving up your devices. One of the most popular options is personalized eye glasses in Buckhead that include blue light filtering lenses. These lenses are designed to reduce the amount of blue light reaching your eyes, helping to minimize eye strain and improve visual comfort.

At Family Eye Care Center of Atlanta, we customize lenses based on your prescription, lifestyle, and screen usage - whether you work at a computer all day or switch between devices.
 

Practice Proper Screen Habits

Simple changes can also make a big difference:

• Follow the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds)
• Increase font size and screen contrast
• Position screens slightly below eye level
• Reduce screen brightness, especially at night
