Computer Vision Syndrome (CVS) can affect anyone who spends three or more hours a day in front of computer monitors, and the population at risk is potentially huge with onset of the pandemic, so so many are working from home. Very little today can be done without the aid of a computer, hence we sit or better stand in front of a display that can do damage to our vision if certain considerations are not taken into account. Many of our actions/habits have an unconscious effect that harms our eyes.

Worldwide, up to 70 million workers are at risk for computer vision syndrome,(US 30 million)  and those numbers are only likely to grow. Today I want to focus on the potentially adverse effect computer use can have on our eyes, forget carpal tunnel, neck, and other unintended bodily harms.

The most common computer-related complaint involves the eyes, which can develop a blurred or double vision as well as burning, itching, dryness, and redness, all of which can interfere with work performance. Please read carefully below what has been learned regarding CVS:

  • electronic characters, which are made up of pixels, have blurred edges, making it more difficult for eyes to maintain focus.
  • to give the eyes a comfortable focusing distance, the screen should be about 20 to 26 inches away from the face. The closer the eyes are to the monitor, the harder they have to work to accommodate it. With time you will not be able to focus at a distance and will require ‘prism’ lens not to see double.
  • the University of Pennsylvania’s ophthalmology department advises that the center of the monitor should be about four to eight inches lower than the eyes to minimize dryness and itching by lessening the exposed surface of the eyes because they are not opened wide. This distance also allows the neck to remain in a more relaxed position.
  • overly bright overhead light and streaming daylight force the eyes to strain to see what is on the screen. A bright monitor also causes your pupils to constrict, giving the eyes a greater range of focus.
  • wearing glare-reducing or tinted lenses can help to minimize glare (blue light filters)<-I do this with an orange lens glasses or could check device or glare reduction.
  • Ophthalmologists suggest adhering to the ’20-20-20′ rule: Every 20 minutes, take a 20-second break and look at something 20 feet away <-I use an app for this to remind me


Doc suggests applying warm moist compresses to the eyes every morning and having humidifier on when working or ‘zooming’ on your device.
