Hours and hours in front of cell phones and PCs and visual disturbances are becoming more and more frequent among Italians. First of all, ocular fatigue (or asthenopia) a disorder that often derives, even if not only, from the excessive use of electronic devices. The so-called blue rays that these devices emit – explains the site of ‘+ Sani + Belli’ – in fact require our eyes a much higher effort than normal to focus and so the muscles of the eyeballs risk not withstanding the effort. The eyes are in fact simple muscles and like everyone else they can suffer from work overload and go to stand-by. Here then, among the most common symptoms, pain, burning and dry eyes begin to manifest. But also photophobia, distorted vision, headaches and many others. However, ocular fatigue can also be a symptom of other diseases and for this reason it is essential for those who suffer from it to always contact a specialist. A thorough visit to a specialized ophthalmologist actually helps prevent the disease from worsening, which can become chronic and be associated with many other more annoying ailments, including headaches in its various forms. Fortunately, there are several techniques to relieve eye fatigue: use of artificial tears, thanks to which it will be possible to lubricate the ocular surface; use of lighting suited to the work environment, decreasing the pressure deriving from effort or the use of glasses suitable for our eye.
