Nowadays, according to studies, between 50 and 90% of people who work in front of a computer screen have some symptoms of eye problems. Therefore, you can damage your eyes by looking at a computer screen for too long time. So, you need eye drops to solve these problems.

Wachler says that people often blink around 18 times per minute, which refreshes the eyes naturally. But when looking at the screen of a computer or other digital device the flicker speed is reduced. So, generally the main problem is to be hours and hours of close focus without taking a break, but there are ways to combat the damage.
Another problem is sitting too close to your computer monitor or holding a digital device closer to your eyes than you would normally hold a book or newspaper. Therefore, your eyes will work harder than normal while you strive to concentrate on small print sizes.

This problem has been called the computer vision syndrome (CVS) which can cause eye pain, dry eyes, watery eyes, blurred vision, double vision, sensitivity to light, difficulty concentrating on images, neck pain, headache or a combination of all of the above.
However, there are quick and easy steps you can take to reduce these vision problems.
Like, lower your monitor, so the top of the screen should be level with the user's eyes, allowing a slightly lower viewing angle. Then you can reduce the brightness by tilting the monitor so you do not see reflections from the lights on the front surface of the monitor. In addition, the best viewing distance is between 20 and 40 inches from the eye to the front surface of the computer screen. Besides, correct breathing can relax the muscles of the eyes. And finally the most important thing is to take breaks frequently. By performing all of these tips you will reduce eyestrain and also improve your overall health.

I think that technologies bring many good things but also produce problems that had not existed before.
