Have you ever noticed that your eyes become dry and tired after long stretches working at a computer? When your eyes fatigue, it is more difficult to focus and read, especially for long stretches of time.
There are many causes of digital eye strain, as well as many ways to keep digital eye strain from causing problems. Following the 20/20/20 rule is an easy way to rest your eyes and prevent digital eye strain from prematurely ending a work or gaming session.
What is the 20/20/20 rule? It’s simple: every 20 minutes look at something 20 feet away (or more) for at least 20 seconds. This will give the focusing muscles that you employ when reading or focusing on a screen a chance to rest. Although this can work for short periods of time, a pair of computer or anti fatigue lenses is a much better alternative or addition!
Digital eye strain, as frustrating as it can be, can generally be managed. Request an appointment and we will work with you to determine the cause of your digital eye strain as well as the best ways to manage it.

Most people will experience a general feeling of eye fatigue. Specifically:
There has been a lot of discussion lately (both in the Optometric community and in general) regarding blue light and the impact it can have on our eyes. While studies are still ongoing, there is significant evidence to suggest that blue light – which is part of a spectrum called HEV light (high-energy visible light) – can have effects ranging from disrupting our sleep cycle to causing physical harm to our eyes.
We recommend wearing glasses that filter out blue light as well as employing software – such as f.lux – that adjusts the colour of your screen to reduce your exposure to blue light.
