How Computers and Blue-violet Light Affect our Eyes

Blue Protect Lenses

Wherever we look, our eyes are exposed to potentially HARMFUL LIGHT

We use computers, tablets and smart phones everyday, they cannot be avoided. All these devices omit harmful blue-violet light. We put our eyes through a lot on a daily basis by carrying out more and more visually demanding tasks.

Blue-violet light is all around us:

  1. Tablet devices
  2. Smart phones
  3. PCs and laptops
  4. Flat screen TVs
  5. Sunlight
  6. Energy-saving light bulbs

How can I tell if using computers is affecting my eyes?

If you have any of the symptoms listed below:

  1. Headaches or migraines
  2. Blurred vision
  3. Redness of the eye or sore eyes
  4. Fatigue or eye discomfort
  5. Aching around the eyes or eyestrain
  6. Flickering of the eyelid
  7. Dry, irritated, gritty eyes
  8. Watery eyes
  9. Increased blinking
  10. Increased sensitivity to light
  11. Intermittent double vision
  12. Difficulty refocusing eyes

Keep your eyes protected:

Blue-violet light can potentially damage the cells at the back of your eyes, reducing the risk of developing eye diseases such as age-related macular degeneration, which is one of the leading causes of blindness.

How can I help?

It has been scientifically proven that blue light is both stressful and harmful to the visual system. This is because blue light has a short-wavelength, which is close to UV light on the light spectrum and can cause more eyestrain. You can protect your eyes from excessive exposure to blue light from your computers/ tablets and smart phones with a blue-free coating treatment on your glasses. The blue-free coating will reduce the amount of blue light passing through your lenses into your eyes. This coating has been designed to reduce eye fatigue and help prevent disrupted sleeping patterns, as blue light affects levels of the sleep-inducing hormone melatonin more than any other wavelength.

Computer Vision Syndrome (or Digital Eye Strain) can be reduced by:

  1. Using the correct spectacles for your needs, which have been designed for the correct working distance from your computer. Wearing optimally corrected prescription glasses with a blue-free coating, which give the greatest comfort at the computer. The Health and Safety (Display Screen Equipment) Regulations from1992 state that, if an employee requires glasses specifically for the VDU, the employer is obliged to pay
  2. Positioning of your chair and computer to prevent back/neck problems. The ideal positioning of the computer screen should be approx. 20 inches away and slightly lower than your eye line
  3. Follow the 20/20/20 rule. Every 20 minutes, look at a distance 20 metres away, for 20 seconds to reduced eyestrain
Catch your eye problems early and prevent disease progression
