What is Computer Eye Strain?
Computer eye strain or also known as computer vision syndrome describes the effects of blue light emitted from the computer screen and other electronic devices resulting in eye strain. Eye discomfort comes from using electronic devices for an extended period of time. Some people are affected, while others are not. However, researchers suggest that as computer and cell phone usage becomes an integrated part of our lives, the risk of computer vision syndrome will increase.
Symptoms of Computer Eye Strain Syndrome:
- Blurred Vison (very common)
- Dry Eyes
- Eye Strain
- Difficulty Falling Asleep
Causes of Computer Eye Strain Symptoms:
- Poor lighting
- When using a computer, especially at night, make sure to have enough background lighting so that the blue light gets “diluted” so-to-speak. This prevents your eyes from focusing only on the screen.
- Glare On Digital Screen
- Blue light emitted from your computer screen can also create a glare, which is completely unnatural to your eyes.
- Improper Viewing Distances
- Try to distance your self a few feet from your computer screen. This ensures that your eyes don’t absorb higher quantities of blue waves.
- Poor Seating Posture
- Posture is very important when using a computer. Always sit with a straight back, with your face a few feet from the computer screen.
How to Prevent Computer Eye Strain?
Preventing computer eye strain involves changing a few daily habits.
- Computer Glasses
- Yellow-tinted computer glasses are designed to block blue light (also known as “blue blockers”) emitted from your computer, tablet, or phone. The normal “visible” light that humans are designed to see does not include blue light. This is why eye strain from persistent computer use occurs. Consider looking at the chart below.
- Consider Tinting your computer/phone display.
- If you’re using Mac/Windows, head over to https://justgetflux.com/ and download a free program that will automatically tint your screen display based on the time. That way you can be sure that you have minimal exposure to blue light.
- Android and iPhone now have built-in apps that add a yellow tint to your device as well. Check out the guide here on how to activate “night shift” mode on iPhone
- Take a Breaks
- Rest frequently so that your eyes don’t get tired quickly from the computer. Research suggests that your eyes blink less when using a computer. What this does is it prevents your eyelids from moisturizing your eyeballs at a normal frequency.
- Consider buying computer glasses
- Shade Glass USA offers premium computer glasses that block blue light from all of your devices. Checkout their glasses here and see if it helps.
- Use Computer Eye Drops
- I was browsing Amazon and came across Similasan Computer Eye Drops. I tested these drops myself and they offer instant relief. Give them a shot! I’m ABSOLUTELY positive you won’t regret it.
Effects Of Computer Eye Strain On Sleep:
Computers and other digital devices have been proven (see sources below) to negatively affect your sleep. Here’s the quick breakdown:
When your body is tired, your brain releases a hormone called “melatonin”. The job of melatonin is to tell your brain that it is time to go to sleep.
When your eyes are constantly using a digital device, blue light tells your body to stay awake, thus inhibiting melatonin production.
This affects your Circadian Rhythm, which is your body’s natural regulatory sleep cycle manager.
