Millions of people across Europe and the UK are seeking safe ways to view the solar eclipse on Wednesday, Aug. 12 [3].
Directly viewing the sun without proper protection can cause permanent retinal damage. Because certified eclipse glasses have sold out in many locations, public health warnings emphasize the need for alternative viewing methods to prevent blindness [5].
This event marks the fullest solar eclipse visible in the UK for the next 54 years [1]. While the primary view is centered over Europe and the UK, millions of people across 26 U.S. states and Washington, D.C., will see a partial eclipse [6].
Experts suggest several indirect methods to observe the event without looking directly at the sun. Sky News said three safe viewing methods are recommended [4], while Yahoo UK said five are suggested [5]. These methods typically include indirect projection, such as using a pinhole filter to cast an image of the eclipse onto a flat surface.
Other safe alternatives include using a colander to create multiple small projections, or viewing the event through specific safe optical devices. These techniques allow the observer to see the progression of the eclipse without exposing the eyes to harmful solar radiation.
Public safety officials said that standard sunglasses, smoked glass, or homemade filters are not sufficient to protect the eyes. Only ISO-certified eclipse glasses provide the necessary filtration to block the intense light and ultraviolet rays emitted by the sun.
As the eclipse progresses this Wednesday, viewers are encouraged to use these indirect methods to ensure they can experience the rare alignment without risking their vision [2].

The scarcity of certified eyewear highlights a recurring public health challenge during major astronomical events. When demand outstrips supply, the risk of retinal injury increases as untrained observers may turn to unsafe DIY filters. The shift toward promoting indirect projection methods—like pinhole viewers—is a necessary mitigation strategy to prevent a surge in emergency ophthalmology visits across Europe and the U.S.
