Complaining about unwillingness to spend a lot of time in front of the computer screen or cell phone is increasingly common.

Speaking like that, it seems like all the blame is on technology. In the opinion of the surgeon-ophthalmologist Renato Neves, president of the Eye Care Hospital of Eyes, it is all about knowing how to use the equipment without harming the vision. "Between 50% and 90% of people who use a computer at work or study often resent this exhausting experience at some point, resulting in decreased productivity, increased errors, and very often problems with vision. , then watch out for two key points: blinking and keeping the monitor's correct distance. "

 Blinking less, your eyes begin to become dry and irritated

Numerous studies prove that people spend much more time using the computer than they usually spend reading a book, for example. Regardless of content, getting 'glazed' eyes on the computer also means blinking less. "When you blink, you spread a teardrop layer all over the eye, keeping you hydrated." Blinking less, your eyes begin to become dry and irritated, "says Neves.

 When you read a book VS When you work on computer 

Still regarding the difference between reading on the computer and reading a book, the specialist calls attention to the positioning of the eyes. "When you read a book, you usually tilt your eyes downward, causing them to be covered in large part by the eyelid and somehow protected. In front of the computer, you usually keep your eyes straight, wide open, and more exposed to dryness. In addition to blinking less, we often come to Dry Eye Syndrome or Computer Vision Syndrome. "

 How far distance can harm the eyes

Neves also warns of how far distance can harm the eyes. "The ideal thing is that the computer monitor is within 50 centimeters of the user.When using a notebook, normally the eyes are within 30 centimeters or less of the screen.If anyone is accustomed to reading everything on the cell phone, The problem is that the eyes have to work much harder to focus on short distances - which requires more effort and causes visual fatigue. do is increase the size of the letters and keep the arm extended when exchanging messages over the phone or browsing the internet. "

In addition to blinking and keeping distance, other considerations of the physician contribute to prevent eye problems from excessive use of these technologies. "It's no wonder that the new equipment allows for various adjustments in terms of brightness, size, definition, contrast and color. Make the adjustments in a personalized way, trying to leave the screen background neither as clear nor as dark, adjusting the size of the letters and opting for a contrast that is comfortable to the eyes is best demanded.
