Do you use your computer or cell phone most of the day? Did you know that looking at a screen all day can make your eyes tired?
Experts say that looking at computers, tablets and smartphone screens does not permanently damage your eyesight. However, there are reports that doing so can cause some annoying side effects such as headaches and poor eyesight.
Many adults and children experience eye problems and vision problems due to long-term use of devices such as computers and mobile phones. According to The American Optometric Association, vision problems are one of the most common health problems among computer workers. Studies show that 50-90% of computer users experience symptoms of computer vision syndrome. In addition, reports indicate that the longer you look at the screen, the worse the level of discomfort.
Looking at a computer screen most of the day can cause side effects such as eye strain, headaches, blurred vision, neck and shoulder pain.
In addition to the above symptoms, children may show attention deficits, poor behavior and irritability, which can lead to learning disabilities.
But you can also reduce these complications if you follow the right steps
-
Blinking - The average blinking eye should be between 12 and 18 beats per minute. However, the frequency of these blinks is very low when using a computer or mobile phone. Frequent cataracts are essential as tears help keep the eye active.

Font size - The computer screen should be large enough to read the letters, even at a distance.

Rule 20-20-20 - Follow the 20-20-20 rule, taking a 20-second break every 20 minutes to look at objects 20 feet away. This method is used by people who work with computers most of the day all over the world.
-
Computer screen - The computer screen should be 20 inches (arm's length) away from the screen, about 6-8 inches below your eye level, and the screen should be tilted at an angle of 15 degrees when using a computer. It is also important to keep the computer screen in low light. This should vary depending on the light in the room and it is not advisable to have only the screen light in the room where you are.

Room lighting - Avoid direct light on the computer screen. For this it is advisable to use an anti-glare screen. You can use curtains to control excess light inside your cabin.

How to hold the keyboard - The keyboard should be below the elbow and there should be a place to hold the wrist in front to keep the hands straight. This place should be smooth and you can use a comfortable chair to help keep your hands straight.
In addition to the above, if you spend most of the day working with computers, tell your family doctor and refer you to the right ophthalmologist. Many doctors offer this service for free, and if you follow the ophthalmologist's instructions, you can further reduce the risk of damage to your eyesight by looking at the screens.
