How do we define eye fatigue? Eye fatigue can be defined as a condition, also known as asthenopia, which is characterised by the following manifestations: ■ Burning and stinging sensation in the eye. ■ Redness and sensitivity. ■ Watery eyes. ■ Visual problems. For example, problems with focusing, blurred vision, sensitivity to light, etc., may occur. ■ Headache. ■ Dizziness. ■ Cervical contracture and pain. What causes it? In most cases, this is due to excessive eye strain and unhealthy habits. It is true that for some users it is difficult to reduce the number of hours they spend in front of the computer, as it is an integral part of their work. However, there are tricks to make this exposure less harmful to the eyes and prevent it from triggering negative effects. The treatment for asthenopia basically consists of changing certain daily habits. Some people require special treatment or the use of eyeglasses to reduce eye fatigue. These types of solutions must be prescribed and monitored by a professional in this field. What is the treatment? Adjust the lighting: We must adjust the lighting of both the environment and the screens. When working at a desk, place a light behind you and focus it on the document. This way, the glare does not shine directly into your eyes. It is also important that the lighting on computer, tablet or mobile screens is not too bright. Keep your distance: The computer screen should be about 60 centimetres away from your eyes. If you use your mobile phone frequently, try to place it approximately 35 centimetres away. Protect yourself from light: Blue light is highly damaging to our eyesight. Fortunately, there are prescription and non-prescription lenses that block this type of light. Take breaks during work: Work for periods of about 20 minutes and take a short break. During the work break, however, avoid picking up other electronic devices such as mobile phones. You can use this time to do some back stretches. Pay attention to the hours of sleep: Ideally, you should sleep about eight hours a day, but you should also make sure that you get a good night’s sleep. Create a pleasant environment in your bedroom before going to bed. Use artificial tears: You can buy artificial tears in any pharmacy to relieve dryness. If the drops you use have preservatives, do not use them more than four times a day. If you have red eyes, it is better not to use them. Blink frequently: Another trick to refresh your eyes is to blink your eyes repeatedly. This action produces tears to moisten the inside of the eye. Take up hobbies that take you away from screens: Enjoy your free time away from screens. Choose to do some sport, for example, go for a run or go hiking.
