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.

Today, the typical child gives above 8 hours of his daily time to digital screen usage. This is expected to increase with time.
