We humans love to stare into our smart devices. We gaze for hours—about 10 hours and 39 minutes a day—at our computers， smartphones， tablets and televisions.1It might be mainly because as we stare at our devices we are exposing ourselves to blue light.

Blue light is a type of electromagnetic（电磁的） radiation with a very short wavelength that produces a high amount of energy. While its true that light can damage our eyes under certain circumstances， theres no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is， which is why blue?light?blocking glasses are so popular.2

Dr. Rahul Khurana， clinical spokesman for the American Academy of Ophthalmology， told Business Insider， “ 3However， theres no evidence that it may be causing serious damage.”

4In fact， the sun is the largest source of blue light. Moreover， blue light is also present in LED light. But if blue light isnt harmful， then why are we constantly rubbing our eyes when were looking at our screens？ The answer is eyestrain（眼疲劳）： More than 60 percent of people experience eye problems associated with digital eyestrain. And blue light， it seems， isnt the cause. Instead， our eyes are so strained because most of us blink less when we stare at our digital devices.5

A. So do the glasses work？

B. Is all this staring bad for us？

C. Blue light exposure is nothing new.

D. Visible blue light is much more complex than you might think it is.

E. In our day?to?day lives， we are exposed to both visible and invisible light.

F. Everyone is very concerned that blue light may be causing damage to the eyes.

G. So if eyestrain is the issue， blue?light?blocking glasses are probably of little use.
