ROTTERDAM - Eye specialists are urging people to protect their eyes when watching Wednesday’s solar eclipse. Looking directly at the sun without adequate protection can damage the retina, potentially causing permanent vision problems without any immediate pain.
According to specialists at Rotterdam Eye Hospital, only eclipse glasses that meet the ISO 12312-2 safety standard are suitable for directly viewing the sun. Regular sunglasses, welding glasses and improvised alternatives do not provide adequate protection.
Retinal damage can result in a dark spot or distorted vision and may not always disappear.
Doctors also warn against viewing the eclipse through CDs, DVDs, smoked glass, photographic negatives, reflections in water, or through a smartphone or camera screen.
A safe alternative is indirect viewing, such as making a small hole in a sturdy piece of paper and projecting the sunlight onto a wall. A colander can also be used to observe the changing shape of the sun.
