Do filters protect from X-rays & ultra-violet radiation?
The emissions of X-ray and ultra-violet radiation by modern monitors are so low as to be undetectable from background radiation. Thus we feel there is no danger here despite the ‘scare’ tactics used by some manufacturers and distributors to hype their filters. In any case, glass filters will reduce ultra-violet radiation because glass has that property, but we suspect few people want to use their filter as a sun shade. Only filters made with glass that contains lead can protect against X-rays. Very few, if any, of today’s filters are made using glass that contains sufficient lead for X-ray protection. But then there is no need as the CRT’s glass already shields against X-rays as explained above.
