Q:

My children never seem to be away from a digital device. Are there any vision problems associated with excessive usage? -- Worried

A:

Optometrists are increasingly concerned about excessive digital usage leading to a strain on the eyes. Children can avoid this by taking a 20-second break every 20 minutes and viewing something 20 feet or more away.

Optometrists are also increasingly concerned about the kind of light everyday electronics devices give off and how those rays might affect and even age the eyes.

In addition, children who normally do not require the use of eyeglasses, according to the American Optometric Association, may benefit from glasses prescribed specifically for intermediate distance for computer use. And children who already wear glasses may find their current prescription does not provide optimal vision for viewing a computer screen. An eye doctor can provide recommendations for each individual patient.
