• Are blue-filtering sunglasses not recommended for those with anxiety?


    Question:

    I have switched to blue light- and UV-blocking glasses. They seem to block both blue light and UV light. Do you think that they are bad for people who suffer from anxiety and panic attack? Maybe blue light is important for those people?


    Answer:

    I don’t think there is enough data to answer your question. Seasonal affective disorder, which is basically depression when the days get short, is occasionally treated by light boxes. Whether blocking blue light can aggravate depression or anxiety has not been determined. However, based upon what is known it certainly is possible.

    Because blue light can adversely affect sleep and your body’s biological clock, in may be best to use blue blocking lenses after dark. UV-blocking lenses are universally recommended since the risks of UV light exposure far outweigh any documented benefits.
