The Five Reasons You Should Wear Blue Light Glasses When Using Computers

You spend 8 hours a day, five days a week staring at a screen, which is about half of your waking time — that's 1/3 of your life! Whether you work in an office or from home, there are plenty of reasons to wear blue light glasses.

Your eyes are delicate and need to be protected when using a computer for extended periods of time. Digital eye strain is a problem occurring globally and affects all working people. It can cause dryness, irritation, blurriness, headaches, insomnia and eye fatigue. It can also affect your posture and cause neck and shoulder problems due to these issues.

Here are the five most common ways computers damage your eyes.

Dry Eyes


Dry eyes are treatable, but they are more uncomfortable than most people realise. Dry eyes can be caused by technology because when you look at something close to your face, your eyes blink less frequently. Tears evaporate quickly, leaving the eye's surface dry. If this continues, your eyes may become:

  • light sensitive
  • red
  • inflamed
  • dry
  • fatigued

Taking breaks, wearing eye protection and using eye drops can be beneficial. When using technology for an extended period of time, take frequent breaks, blink frequently,


Excessive use of digital devices can cause tension headaches. This is due to the fact that staring at a screen for an extended period of time causes eye strain. Your eyes are straining to read small, dark text against a white screen (likely as you are right now). The muscles in the templates spasm as your eyes strain to see this information.

Sleep Quality

Blue light is everywhere. It’s in sunlight. But it’s especially common in digital devices. Blue light inhibits the release of melatonin, a hormone that causes us to sleep. While this is useful during the day, it is detrimental at night when we are attempting to sleep. Blue light exposure in the evening can fool our brain into thinking it's still daytime, disrupting circadian rhythms and leaving us feeling alert rather than tired.

Retina Damage

You're not alone if you bring your laptop or smartphone to bed. Unfortunately, staying up late on digital devices can cause retinal damage. The blue light emitted by LED devices can damage the retina and cause macular degeneration, a condition that affects your central vision. This risk increases with age.

Computer Vision Syndrome

How does working on the computer all day affect your eyes? Computer vision syndrome (CVS) is a condition that results from staring at the screen for long periods of time. Nearly everyone who works from a computer on a daily basis will experience some symptoms of CVS. The symptoms of CVS include blurry vision, eye strain, watery eyes and sensitivity to light.

How can we prevent the effects of prolonged screen time?

To begin, wear blue-light-blocking glasses. Blue light-blocking computer glasses are distinct from regular glasses. They are specifically designed to protect your eyes from the effects of excessive screen time and harmful blue light exposure. Blue light from electronics is linked to issues such as:

  • dry eye
  • blurry vision
  • eyestrain
  • macular degeneration
  • cataracts
  • sleep issues
  • headaches & migraines


Let’s have a look at the benefits of wearing blue light glasses:

  • Relieves eye discomfort, headaches and helps your eyes focus better.
  • Help reduce glare and sleep better by reducing blue light exposure from digital devices.
  • Reduction of damaging blue light
  • Helps in reducing CVS symptoms and preventing age-related macular degeneration.
  • Improved productivity
  • Improved sleep quality
  • Lowering stress hormone levels

There are so many benefits, to using blue light blocking glasses, and this is why blue light blocking glasses or filters, such as the Ocushield products, are used to limit the effects of blue light emitted from devices such as laptops and mobile phones.
