Longer Working Hours May Lead To Computer Vision Syndrome

B.C Optometrists Provide Tips To Office Workers On How To Minimize Eye Strain From Computer Use

  • ​If you have prescription glasses or contacts, wear them while using the computer.
  • Have an anti-reflective coating with a blue filter applied to your glasses to reduce the discomfort and monitor glare.
  • Follow the 20-20-20 rule. Every 20 minutes take a 20 second break and focus you eyes on something else for at least 20 seconds.
  • Try using artificial teardrops or concentrate on blinking regularly if your eyes bother you.
  • Arrange your computer monitor to be ergonomically correct. Place your monitor approximately 20" from your eye, with the center of the monitor just below your eyes. Make sure it's free from fingerprints and dust for clarity.
  • Adjust your monitor's brightness so it's not too bright or too dim.
  • Minimize monitor glare by using window treatments, dimmer switches and anti-glare screens.
  • Eliminate sources of bright light (windows or lights) from your field of vision.
  • Attach a clipboard alongside your monitor if you alternate between the screen and paperwork

New Innovative Lens Technology - Blue Light

For those of us who must spend time in front of screens, there are ways that we can more actively protect our eyes against the harmful effects of blue light. Advances in optical lenses have provided a great new option to help us filter out the high-energy light that would otherwise penetrate the front of our eyes and potentially result in digital eye strain. These lenses, which we generally refer to as blue-blocking or blue-filtering lenses, are a great option for anyone, young or old, who spends time in front of screens.

As we continue to integrate digital devices into various facets of our lives, it’s vital to remember the potential effects that these new technologies can have on our health. Protecting our eyes today can allow us to preserve our vision in the future.

Protect Those Peepers

Recent Canadian National Institute for the Blind studies statistics have found that 3 out of 5 workers with serious eye injuries were not wearing eye protection at the time of their accident. Of those who were wearing protection, 40% were wearing the wrong protection. Accidents can happen in the garden, playing a sport or at home. If you have only one good eye you need to wear protection all the time. Please ask about the right eye protection for you.

The Clear K Laser

Stay tuned for new AMD treatments:
Update on the LEAD study from the University of Melbourne using the 2RT and CPV lasers

Exciting news! The LEAD Study, published recently in the journal of Ophthalmology , confirms the value and safety of using the Clear K laser as a means of arresting progression of macular degeneration.

This study indicates that the Clear K laser could be used in those candidates with intermediate AMD without clinically significant reticular pseudo drusen. In the study treated patients were 4x less likely to progress than controls with 12 spot treatments in one eye.

This treatment is still in its early stages of trial but there is the potential for superior outcomes as the number of laser treatment spots are increased and as it is used in both eyes.

The Eye Deciphered

Harvard researchers were very excited to demonstrate that the retina holds the majority of the 20,000 genes in the human body! Not surprising, as we already know that the eye is a complex organ carrying more than 60 types of cell. These discoveries will help researchers find the cause of inherited diseases caused by genetic mutations, and provide gene therapy for diseases such as Retinitis pigmentosa.

Omega - 3 Oils and the Eye

Interesting research at the Geriatrics Institute, Sherbrooke found that incubating Retinal Pigment Epithelial cells in vegetable oils and then incorporating them into retinal cells, caused the cells to have beneficial effects. It seems that the vegetable oils increased membrane fluidity, which further facilitates light transmission through the eye. The investigators concluded that a diet low in trans unsaturated fats and high in both omega - 3 fatty acids and olive oil can reduce the risk of the eye developing retinopathies. The researchers further suggested that eye drops should all contain oil with biological properties rather that a neutral oil. ​
