Smartphones and tablets have become the predominant devices people use to help with their daily activities due to their easy access and practicality. They are always within an arm鈥檚 reach, and they are especially useful when you cannot use the computer. However, the excessive use of these devices has raised concerns about the welfare of the eyes and the vision. Therefore, it is important to pay attention to the ambient lighting when using smartphones because poor lighting may cause additional stress to your eyes.
, Director of the Center of Ophthalmology at 麻豆传媒AV在线看 Research Hospital, provides some instructions on using these technological devices without too much strain on the聽vision.
Six tips to avoid stress on your eyes
1. Keep them at the right distance:聽“It changes according to the device used: shorter distance for the聽smartphone聽as it is smaller, and further away for the聽tablet聽as it is bigger.”
2. The screen must have the right light:聽“Often we set a low screen brightness to save on battery power, but this is a cause of stress for the eyes.聽The eye聽tires if the smartphone or tablet has dimmed lighting because the pupil enlarges and the area in sharp focus becomes smaller. Thus, sometimes one does not understand what is being observed.”
3. What does a small screen mean? “The small size of the screen is a particular problem for those suffering from聽presbyopia, a visual disorder that is age-related and that can arise after the age of 40. People who are farsighted have difficulty focusing up close and reading well the information on a聽smartphone聽or a聽tablet.”
4. Choose聽an 鈥渋ntelligent鈥� smartphone聽and/or聽tablet:聽“There are devices that reflect ambient light and those who have their own lighting.聽The first require an intense ambient light, while the other devices have a measurement device that best adapts to the ambient light.聽It is up to the user to set the sensor properly.”
5. The resolution is fundamental:聽“It is very important that the screen has a good resolution: the lower the resolution, the worse the image quality, and the more the聽eye聽gets tired, even more so in those who have refraction disorders.”
6. Those who use a tablet should occasionally let the聽eyes聽rest:聽“The use of a smartphone聽is more persistent and frequent, while the use of a聽tablet聽can be prolonged or occasional.聽Therefore, it is important to take breaks to rest the vision and the eyes.”
If you can choose, choose the printed page
“For the聽eyes聽a printed page is always better than a “digital” page. Technological devices have made people proactive, everything is relying on the technology and its benefits and an effort is made 鈥嬧�媡o read even in poor conditions that can stress the vision.聽In cases of a printed page, there is no doubt聽that its content should be read under sufficient lighting and physically it should be in good reading conditions. The print also helps to store information, especially for those who have a good visual memory.”
