Stores and cultural venues across Amsterdam are running out of certified solar eclipse glasses as residents prepare for the upcoming celestial event.
Outlets including Atheneum bookshop, the ARTIS zoo museum shop, and branches of ANWB, Normal, and Kamera Express have already sold through their inventories.
The museum shop at NEMO Science Museum, which is hosting a viewing event on its roof terrace, has also run out of stock and confirmed that no additional deliveries are expected.
The high demand follows safety measures taken by major online retailers, with online store Bol removing dozens of solar eclipse glasses from its marketplace after failing to guarantee they met safety standards.
Severe risk of permanent eye damage
Ophthalmologist Hans Vingerling warns that looking directly at the sun without proper protection can cause immediate and irreversible harm. Because the retina lacks pain receptors, individuals will not feel damage occurring while looking at an eclipse.
Instead, injured viewers only notice the effect afterward when a dark spot appears in the center of their vision. Sunlight is powerful enough to burn the retina within seconds, and because retinal tissue cannot regenerate, the resulting vision loss is often permanent.
Improvised filters fail to protect eyesight
Eye specialists strongly advise against using makeshift solutions to view the eclipse. Standard sunglasses, no matter how dark, do not filter out the harmful radiation that damages human eyes during solar viewing.
Alternative home methods, such as looking through CDs, photographic negatives, smoked glass, or water reflections, are equally unsafe. Experts emphasize that homemade viewing contraptions should be avoided entirely in favor of certified equipment.
Look for official safety certification
To safely view the event, people must use purpose-built eclipse glasses that carry an official CE safety marking. Uncertified glasses purchased online may lack the necessary filters required to block dangerous rays.
Without certified protective gear, medical professionals advise using indirect projection methods, such as a pinhole projector, rather than looking toward the sun.
