• A new study has shown how blue light can cause macular degeneration — one of the leading causes of blindness.
• Blue light harms our vision by damaging the eye's retina.
• The study found blue light turns a molecule in the eye into a cell-killing poison.
• It kills photoreceptor cells, which do not regenerate.
• Special sunglasses that filter blue light might hep, but specialists are undecided about how much good they actually do.
