Looking after our Eyes in our Multi-Screen Daily LivesThe number of electronic devices that we use on a daily, hourly or even by the minute is on the increase. Quite commonly and rightly we blame our screens for a series of harmful effects on our eyesight and eye comfort. In some cases this is unsubstantiated, but in many cases the change in our lifestyle has led us to have dry eyes, with burning, stinging, redness, grittiness and a sensation of sand in the eyes.
In general, the images are seen on a screen, whether it be TV, computer, tablet, mobile phone or another electronic device is not a static image. They are instead produced by a continuous succession of images, and that is what is causing eye strain.
Another practice that influences our eye fatigue is, when we use computers or mobile phones, we stop blinking. We are constantly staring over at a short distance, which involves a larger focusing effort than we would use for seeing far away. The resultant eye strain makes our eyes feel tired, gives us eye discomfort and even headaches, particularly if you suffer from a minor refractive (glasses) error that has not been fully corrected with suitable glasses or contact lenses.
In short, looking at screens does not actually pose any serious risk for eyesight, but over exposing our eyes to them in unsuitable conditions, which can also include bright lights in the office and air conditioning, may go hand in hand with eye strain, which is particularly pronounced if there are previously uncorrected eye defects.
At Clinica London, we come across many people with non-specific eye problems, like sleepiness, irritated or dry eyes, due to their immense computer and mobile phone use. Virtually all of these symptoms can be ascribed to a reduction in blinking and subsequent decrease in the tear secretion, particularly in those areas with the air conditioning and low humidity.
