Overview
- On Saturday, July 18 the Colegio de Ópticos‑Optometristas de Castilla y León published a detailed safety decálogo urging the public to follow certified guidance for the August 12 total solar eclipse.
- The college says only ISO 12312‑2 certified eclipse glasses or certified solar filters fitted in front of binoculars, telescopes or cameras provide safe direct viewing and that improvised methods such as sunglasses, radiographs or CDs are unsafe.
- Opticians warn that glasses must remain on for every non‑total phase and may be removed only during true totality inside the path of totality because looking at the sun outside totality can cause painless, permanent macular burns.
- Regional authorities have announced exceptional mobility measures, including a one‑day truck circulation ban and plans to clear major roads to prevent dangerous roadside stopping, while transport operators warn of possible delivery delays.
- Rural low‑light areas expect a large tourism influx and scientific outreach events over the next years, so officials are combining public education, medical readiness and local service planning to protect visitors and maximize economic benefits.
