Do you find your eyes become fatigued after only a short time on the computer? Are you always having to tilt your head back in order to read the screen? Here are some tips that can help correct these problems.

Make sure your prescription is up to date – Usually prescription changes happen gradually; often times you won’t notice the change until it has become significant. This leads to eye strain, particularly when working in the intermediate and close ranges such as computer work. To avoid this, it is important to have your vision checked every year to ensure you are getting the most from your glasses.

Have a dedicated pair of computer glasses – It may be tempting to try to find glasses that will work in all situations, but the truth is there is no pair of glasses that will work perfectly in all situations. If you do a lot of work on the computer, it is important to have a dedicated pair of computer glasses that are set to have the maximum clarity at the distance of your computer screen. The power of the lens needed for the distance of the screen is different than the power needed for distance or reading vision. If you’re over 40 and using bifocals, trifocals, or progressive lenses, the limitations of your lenses can greatly impact your ability to see the computer. A lot of times this will cause you to move your head to an unnatural position to see the computer screen in focus. This not only leads to eye strain, but also neck and back fatigue. In a pair of dedicated computer glasses the lenses are made to provide a large viewing area with that specialized power for the computer so you don’t have to adjust your head to see the screen. Because of this your head and neck will be in a normal position, reducing fatigue and improving productivity.

Make sure your lenses filter blue light – Blue light is generated by computer, tablet, and phone screens. This particular wavelength of light is damaging to the eye and disrupts sleep patterns. Prolonged exposure to blue light during the work day can cause eye fatigue. It is also important to have an anti-reflective coating on your lenses. This type of coating helps to reduce glare from your computer screen, allowing the eye to focus easier.

Use the 20/20/20 rule – When working on the computer your blink rate is often significantly reduced. Typical blink rates are around 60 blinks per minute, but when working on the computer this can drop to as little as 10 blinks per minute and studies show that many of those are not actually complete blinks. As a result, the eye dries out easier and becomes fatigued faster – often leading to Computer Vision Syndrome. You can help avoid this by practicing the 20/20/20 rule. Every 20 minutes look away from the computer screen at an object at least 20 feet away. Completely close your eyes slowly, then open your eyes and focus on the distant object; do this 20 times.
