Yes, prolonged and excessive exposure to screens can contribute to the development of certain eye diseases. The symptoms are red eyes, intermittent blurred vision, burning eyes and sometimes chronic headaches. This can happen on a computer screen, television or mobile phone. It is therefore advisable to take regular breaks every 20 minutes by closing your eyes or looking into the distance for 20 seconds. You will need to wear suitable optical correction depending on your vision test. You should also make sure that your direct and indirect lighting is appropriate, and if you spend long periods on a computer screen, don't forget to apply artificial tears regularly during the day. If the headaches persist and the symptoms worsen, consult your ophthalmologist in Geneva without delay.
