Total eclipses of the Sun are amongst nature's most magnificent spectacles, and offer the opportunity for an exceptional educational experience. Many people never see one in their lifetime, but it has been estimated that this August's eclipse will be seen by more people than any other. It would be a sadly lost opportunity if they were denied the experience because they fear a danger that is easily avoided. The dangers of eye damage are real and precautions need to be taken. Staring at the bright solar photosphere can cause temporary or permanent retinal damage. Since the retina has no pain receptors the observer can be unaware that the eye is being `cooked', and the damage may only become apparent several hours later. However, when the photosphere is completely blocked by the Moon during the brief period of totality (two minutes or less), it is quite safe to look directly. In fact, you will not otherwise see anything at all. It is a complex message to get across to the public, and especially to children, that protection is required during the partial phases but not during totality, and that those outside the path of totality require protection for the whole eclipse. The National Eclipse Group was established by PPARC in 1997 to coordinate educational activities, issue public information and give authoritative advice for the 1999 eclipse. It has published a Solar Eclipse Safety Code, which is available on the national eclipse web site (mentioned above). It advises that the saf
