It is not uncommon for office workers who spend a good portion of their day in front of a computer to complain about headaches and neck, back and shoulder pain. Looking at automated screens for too long may also cause screen-induced eye strain, more commonly known as computer vision syndrome (CVS), and visual discomfort.

CVS is usually the result of digital screens that emit both ionizing and non-ionising light. The degree of the damage is often so low that it remains unmeasurable. One of the common causes of screen-induced eye strain includes the build-up of an electrostatic charge on the screen’s surface which collects dust on the screen. The charges and dust are factors that may lead to eye irritation.

Symptom of Eye Strain

Eye fatigue from excessive computer use can be mostly due to your eyes constantly adapting to different contrasts and brightness levels up to 30 000 times a day. Many people may become concerned how this could negatively affect eye health, but there is no evidence that digital displays cause eye diseases or permanent damage.

The extent to which an individual would experience sensitivity in their eyes largely depends on his/her visual abilities and the degree of the visual demands of a task. Poor computer design, workplace ergonomics, and highly visual demanding tasks can all contribute to the development of visual symptoms and complaints. 


How to Minimize screen induced eye strain :

  1. Check if your lens prescription is up-to-date.

  2. Sometimes changing your contact lenses to spectacles when working in front of a computer may help to reduce eye strain. If your eyes, with or without contact lenses, become dry, blink more or use eye drops as advised by your optometrist.

  3. Choose a comfortable and supportive chair that supports an ergonomic sitting posture. This also means adjusting your computer monitor and all other equipment at your work station to reduce strain.

  4. Every 20 minutes rest your eyes and allow them to wander around the room or look out a window. Do this by looking six to seven metres away for approximately 20 seconds. Taking a break with a brisk 10 to 15 minute walk at least every two hours also helps to refresh your eyes.

According to the Vision Council of America, untreated eye problems and vision loss reduce worker productivity by 20%. It is therefore important to schedule regular eye examinations with your optometrist. Not only does an eye test determine the condition of your eyesight, but it is also a general health check for abnormalities and early signs of eye problems.

It is important to Valuate Your Supplements and Vitamins before. Optometrists are often the first health care professionals to detect chronic systemic diseases such as high blood pressure and diabetes.
