Directly Watching the Sun Can Cause Irreversible Damage
Residents of the Canary Islands are set to witness a partial solar eclipse this Wednesday, but failing to take proper precautions could lead to serious eye injuries and increase risks for drivers.
The eclipse will obscure up to 77% of the sun’s surface across the archipelago. As there will be no totality phase, it’s crucial to wear protective glasses throughout the observation.
Risks of Solar Viewing
The main hazard is solar retinopathy, a condition that can occur when looking directly at the sun without proper protection. What’s alarming is that damage can happen without immediate pain or symptoms, leading to blurred vision, dark spots, distorted images, or even loss of visual clarity hours or days later. In some cases, the damage may be irreversible.
To safely view the eclipse, only approved solar observation glasses that meet the EN ISO 12312-2:2015 standard should be used. Regular sunglasses, no matter how dark, are not sufficient. Homemade filters, smoked glasses, X-rays, or CDs also offer no protection.
It’s also vital to ensure telescopes, binoculars, and cameras have specific solar filters attached to the front. Looking through such devices without eclipse glasses can cause severe harm due to concentrated radiation.
Driving Caution
The DGT (General Directorate of Traffic) warns that driving during this event can be dangerous. If you’re behind the wheel, avoid looking at the sun or using eclipse glasses. Attempting to take photos or video while driving is also unsafe.
Drivers should adjust their speed, maintain a greater distance from other vehicles, and use sun visors if necessary. Stopping on the road or roadside to watch the eclipse is prohibited; drivers must find a safe, authorised parking spot if they wish to observe it.
Heavy crowds at viewing locations can lead to traffic congestion, pedestrians near roads, and access issues for emergency services. Thus, planning ahead and following guidance from security personnel is advised.
Official Viewing Point in Fuerteventura
The Castillo del Tostón in El Cotillo, Fuerteventura, has been designated an official viewing site by the Canary Islands Government. Staff will be present to distribute approved glasses for safe solar viewing.
