In today’s world, we spend countless hours in front of screens—whether it’s for work, school, or leisure. While the convenience of digital technology has transformed our lives, it has also introduced a new challenge for our eyes: blue light exposure. Prolonged screen time is linked to digital eye strain, which can cause discomfort and even affect your vision over time. At Ishigo Optometry, we believe in protecting your eye health by offering insights and solutions to mitigate the effects of blue light.

What is Blue Light?

Blue light is a high-energy visible (HEV) light emitted by digital devices such as smartphones, computers, tablets, and televisions. While blue light is naturally present in sunlight, excessive exposure from screens can lead to eye strain, especially when we don’t take the necessary precautions.
 

What is Digital Eye Strain?

Digital eye strain, also known as computer vision syndrome, refers to the discomfort felt after long periods of screen use. Symptoms include:
 

• Blurred vision
   

• Dry eyes
   

• Headaches
   

• Eye fatigue
   

• Difficulty focusing
   

These symptoms often occur because our eyes must constantly adjust to the screen's brightness, contrast, and glare. Staring at screens for extended periods also reduces blinking, which can lead to dry, irritated eyes.
 

How Does Blue Light Contribute to Eye Strain?

While blue light exposure doesn’t directly damage the eye in the short term, it contributes to digital eye strain in two key ways:
 

• Higher Energy: Blue light scatters more easily than other colors, making it harder for the eye to focus. This increases the effort your eyes need to exert when looking at a screen.
   

• Disruption of Sleep Patterns: Blue light interferes with your body’s natural sleep-wake cycle, as it suppresses melatonin production. This can lead to poor sleep quality and further strain on your eyes due to fatigue.
   

Tips for Reducing Digital Eye Strain

Fortunately, there are several ways to reduce the impact of blue light and digital eye strain:
 

• Follow the 20-20-20 Rule: Every 20 minutes, take a 20-second break and look at something 20 feet away. This helps relax your eye muscles and prevent strain.
   

• Use Blue Light Filters: Many devices offer blue light filtering options that reduce blue light emission. You can also invest in blue light blocking glasses, which are designed to filter out the most harmful wavelengths of blue light.
   

• Adjust Your Screen Settings: Lowering the brightness and contrast of your screen can make it easier on your eyes. You can also adjust the color temperature to warmer tones, which emit less blue light.
   

• Maintain Proper Lighting: Reduce glare by ensuring your screen is not directly exposed to bright light sources. Position your screen so that overhead lighting doesn’t reflect off it.
   

• Invest in Blue Light Blocking Lenses: At Ishigo Optometry, we offer blue light blocking lenses that can be added to your prescription glasses or purchased on their own. These lenses are specifically designed to filter out blue light and reduce eye strain, offering an extra layer of protection for your vision.
   

When to Seek Professional Help

If you’re experiencing persistent symptoms of digital eye strain, it’s essential to schedule an eye exam. Dr. Ishigo at Ishigo Optometry can assess your vision, discuss your symptoms, and recommend customized solutions to help alleviate discomfort and protect your eyes from further strain. In some cases, updating your prescription or incorporating specific lens treatments may significantly improve your comfort during screen time.
