The study, published in the June edition of the medical journal Photochemistry and Photobiology, found that CLF (compact fluorescent light) bulbs give off UV emissions strong enough to damage skin.
The damaging UV rays were found to be caused by small cracks in the phosphor coating of energy saving light bulbs.
Normal light bulbs did not give off levels of UV radiation that were considered to be a risk.
The researchers suggested that as a result of their research people with sensitive skin should avoid being at long-term close distance from to energy saving lights, in particular computer screens.
They suggested the use of a second glass screen to protect users from yhe UV emissions from CLF bulbs.
