In today’s technology-driven world, digital devices are almost impossible to avoid. From smart phones to computers and tablets, they’re an essential part of modern living. Unfortunately, many digital device users complain about eye fatigue and discomfort, especially after long periods of use.
However, studies suggest that the digital screen itself isn’t the cause of these symptoms. Digital screens give off little to no harmful radiation (such as x-rays or UV rays).
Digital screens do, however, expose your eyes to blue light. The blue light exposure you get from screens is minimal compared to the amount of exposure from the sun. And yet, there is concern over the long-term effects of screen exposure because of the proximity of the screens and the length of time spent looking at them.
The possible causes for eye strain include fatigue, dry eyes, bad lighting, or how you sit in front of these screens. Here are a few tips that will help you to ease any strain on your eyes:
1. Get a comprehensive eye exam
Having a routine comprehensive eye exam is an essential part of taking care of your eyes. Make sure you tell your optometrist how often you use your computer or other digital devices at work and at home.
2. Use proper lighting
Eye strain is often caused by excessively bright light from either outdoor sunlight coming through the window or harsh interior lighting. Eliminate exterior lighting by closing blinds or drapes, especially if that light source is in front of you or right behind you.
It might also hep to avoid working under overhead fluorescent lighting. If possible, switch off the overhead lights and use floor lamps instead that can provide softer, LED lighting.
3. Minimise glare
The glare from light reflecting off walls and finished surfaces as well as reflections on your computer screen can also cause computer eye strain. Consider installing an anti-glare screen on your display and, if possible, paint bright walls a darker colour with a matte finish.
If you wear glasses, purchase lenses with an anti-reflective (AR) coating. AR coating reduces glare by minimising the amount of light reflecting off the front and back surfaces of your eyeglass lenses.
