Eye strain
Most employees who work in an office will spend the great majority of their day focusing on a computer screen, which can lead to a variety of eye and vision problems covered by the term Computer Vision Syndrome (CVS).
Dr Salber explains that these issues affect somewhere between 64 and 90 per cent of computer users after prolonged use, with symptoms including eyestrain, headaches, ocular discomfort, dry eye, diplopia (double vision) and blurred vision.
'The cause varies by symptom,' she explains. 'Eye strain may be caused by repeated use of the eye muscles in a repetitive pattern, similar to RSI of other muscle groups. Dry eyes may be related to reduced blinking, exposure to air conditioning, or both.'
Although it can be hard to limit your screen time during the working day, Dr Salber notes that there are a number of things workers can do to avoid eye and vision problems or reduce the symptoms.
'Proper positioning of the computer screen, avoidance of glare from the screen by use of anti-glare screens, and taking breaks from the computer are all ways that are recommended to avoid getting CVS,' she says.
'Over the counter products are available that can help with dry eyes, including both drops and gels. If visual symptoms persist, you should see an eye professional to be sure there are no other issues that require treatment, such as a change in refraction.'
