When a headache appears accompanied by visual abnormalities such as having blurred vision, it is usually due to the process known as eye fatigue or tired eyesight. We live in a society in which technological development is an essential part of our daily routines.
Due to this circumstance, our eyes make a lot of efforts throughout the day when they are exposed, either during working hours or during leisure time, to direct observation of screens. Whether on computers, mobile phones, tablets or television screens, the fact of staying with your gaze fixed for a long time can cause symptoms such as eye redness, general fatigue, headaches and blurred vision.
Blurred vision can lead to headaches
If we confine ourselves to the work area itself, there are studies that indicate that those employees who spend more than three hours working with a computer can easily generate symptoms such as those exposed – headaches and blurred vision – which, in turn, will be the triggering more serious problems related to decreased productivity and poor work performance. When the eyes are in front of a screen, they have to carry out a continuous focusing process to keep the vision clear since the images that are presented successively on the computer screen do not always have the same definition.
The factors that can generate the appearance of headaches accompanied by symptoms of eye fatigue such as blurred vision, can be of a very diverse nature: poorly corrected eye pathologies such as astigmatism, farsightedness or myopia, wearing contact lenses during more hours than recommended, accommodation disorders, a poorly lit work space, poor screen resolution, reflections and glare on the screen, poor ventilation of the room where we are, exposure to screens for many hours without a break, and even, emotional problems related to stress or anxiety.
To solve the appearance of these problems, it is necessary to attend, above all, to environmental factors, although it is also useful to seek advice from our trusted doctor in order to rule out more serious pathological processes. In any case, the appearance of headaches linked to blurred vision usually has as its starting point a situation of fatigue on our part and, therefore, we must follow a series of recommendations to avoid these ailments: lighting, ergonomics of the chair or armchair, the position in which we sit, a 10-minute break for every hour of exposure to a screen or avoiding tobacco smoke.
