A doctors organization says staring at blue light on LED screens can cause eye issues. 

"Especially from birth to age three, the crystal lens in their eyes are not fully developed. So, it causes a lot more damage.," said optometrist Dr. Bridgitte Shen Lee.

The American Academy of Pediatrics recommends limiting the screen time of kids older than two to two hours per day. 

Overexposure to blue light from screens can lead to macular degeneration and blindness.

Lee, however, said limiting screen time to two hours is not a realistic solution. 

"What we eye care providers would like to add to that, when the children are on digital devices, it’s important for them to wear eye protection," Lee said. 

That protection can be worn as a coating on eyeglasses and sunglasses with or without a prescription. 

Some shades of blue light are beneficial, such as blue light at night, according to Lee.
