Are PC Screens Blinking?

Computer vision syndrome is a new situation created by the modern world, and it does not actually cause a flaw, that is, it does not "distract" the public. However, it usually causes people to feel 60-80 cm and hours of work, and those who have occult hyperopia or early-onset presbyopia (senility hyperopia) feel these hidden and indistinct refraction defects. Apart from that, the fact that computer screens are constantly flickering, that is, they are actually blinking 40 to 80 times in the first place, the sight is strong, which causes fatigue in the people watching carefully. During a careful glance, our blink count drops to 5-6 minutes per minute (normally 12-16 minutes per minute, which we normally do not need to see too sharp), while slowing down the mechanism that prevents our eyes from drying by clipping, increasing the rate of tear evaporation in air- is another factor that increases the drying of the surface of the eye. For this reason, in order to prevent eye strain and complaints of computer users, it is necessary to consider the following proposal:


The upper level of the computer screen should not exceed the eye level. This will result in slightly gentle position during your eyesight work, which will reduce the surface of the eye from which your eye can evaporate, by keeping your cover area somewhat narrow.


For a person looking at the screen at a distance of 60-80 cm, it is also important to balance the screen resolution with the screen resolution. 640x480 for 14 inch screen size; 600x800 for 15 inch screen size; 1024x768 is the ideal choice for 17 inch screen resolution. This situation will make the vision easier due to the large letters and image images.


Careful work and sharp vision effort will inadvertently reduce the number of blinks. For this reason, when you are facing the screen for 45 minutes, you should be paused for 15 minutes to perform a function that requires less visual attention.


If these measures do not relieve you, you should consult an ophthalmologist for hidden hypermetropia and early-onset premature aging hyperopia, while measuring your tear function.
