Scotland is set to witness its most dramatic solar eclipse since August 1999, with the moon expected to cover up to 95% of the sun. The celestial event will unfold over a period of two hours as the moon gradually moves across the face of the sun before moving away.
Astronomical societies across Scotland are organizing events where specialized eclipse glasses will be distributed. These glasses are essential for safe viewing and can also be purchased online. It is critical that viewers use certified eclipse glasses, which should be clearly marked with the safety certification ISO 12312-2 or ISO 12312-2:2015. Standard sunglasses are not sufficient to protect the eyes from the sun's harmful rays.
Experts warn against looking at the sun directly, even if it does not cause immediate discomfort. The retina can be significantly damaged by prolonged exposure, even from brief glances. Looking at the sun through clouds, which might seem less intense, also poses a risk to eye health.
Following the total solar eclipse in 1999, the Royal College of Ophthalmologists reported approximately 70 cases of vision problems among individuals who had watched the event. Notably, about 40% of these individuals had looked at the sun for less than a minute. Proper eye protection is therefore paramount to prevent similar occurrences during the upcoming eclipse.
