Smartphones, computer screens and tablets display affects the eyesight differently due to pixels. As we focus hard on pixels, our eyes have to work more as compared to while reading a traditional book. Even though digital screen resolution is improving continuously with the help of advanced technology, a few problems still arise due to prolonged usage of computers and other digital devices.

Digital eyestrain is a categorization of eye and vision-associated problems that are caused by extended computer or digital device use. The sufferers habitually undergo eyestrain, puffy eyes and dryness due to less blinking. Blurry vision is also common owing to screen glare. Headaches also spring up because of a low resolution or due to a bad posture, straining the eyes. The symptoms result from using a digital screen for two or more hours every day.

Researchers have indicated we tend to blink less while reading on the computer and this gives way to quite a few problems. The eyes get tired, become dry and itchy. It is interesting to know that e-readers, like Kindle or Nook, enjoy a type of display that is different from computer screens. It is known as E-Ink and strongly resembles the appearance of ink on printed-paper. This is why users of these gadgets are less likely to face eyestrain and affect the eyesight.

Using digital devices in poor light also makes it harder for the eyes to focus, triggering eye fatigue. The risk and intensity of eyestrain increases with the duration of the time you spend looking at a computer strain, and this can also cause headaches. Even though the theory that staring at screens can cause continuing vision problems is still under research, there has been some evidence to establish a connection.
