Flat-panel computer screens like this are considered to be safe.

Can you get UV exposure from a computer monitor?
It all depends on the type of computer monitor that you use.
Old School Monitors Emit Very Low Amounts of UV Light
Old-school, big-box cathode ray tube (CRT) monitors will emit very low levels of UV radiation. According to the Robbins Eye Center of Bridgeport, CT, “Radiation levels from computer screens are so low that a lifetime of exposure will not damage the eyes.”
CRTs all have a fairly thick glass faceplate, and also have been made to emit less UV as of late. To make the picture brighter, the “blueness” has been reduced by pushing their color point to more of the center of the Color Chart. This reduces any amount of UV radiation (Dr Carlo Infante).
Still, if you spend hours in front of your screen at a time, it is best to switch to a flat-screen monitor, or to invest in a monitor anti-glare filter, like one from 3M (starting at $34.89, Amazon.com).
Modern Flat-Panel Screens Do Not
On the other hand, modern flat-panel screen monitors with both LCD and plasma technology emit no detectable UV light. In at least one study, researchers have attempted to measure any UV that might be radiated from LCD screens and were unable to detect any UVA or UVB using meters capable of measuring as low as 1 microwatt per square centimeter (XPS.org).
Keep in mind, though, that “flat-panel” and “flat-screen” are not the same. Flat-panel are safe, whereas flat-screen are almost always are CRTs (see above) that have a flat screen face.
Other Sources of Light Indoors
- Windows. 62.8% of aging UVA rays come in through windows – including in the car. [For more, please read: In the News: The True Effects of Sun Exposure]
- Fluorescent bulbs. Fluorescent bulbs emit a small amount of light in the UV spectrum (GELighting). While small, it is still detectable, which means it can lead to cumulative UV damage over time.
