Blue skies: Be careful with smartphone photos of partial eclipses

Before the partial solar eclipse on Wednesday evening, the Austrian mobile industry association FMK warned against photographing the celestial event with smartphones. Prolonged focus on the partially darkened sun could damage the sensitive image sensor, according to the Forum Mobile Communication. Those wishing to capture the eclipse with a smartphone need a solar filter in front of the camera lens, as sunglasses or improvised filters offer insufficient protection. The reason lies in the concentrated light rays from the optics, which can damage the sensor. This applies to other cameras as well, but no other device category is as widespread and used by as many laypeople as smartphones. Experts assure that with proper preparation, impressive snapshots of the partial solar eclipse can be taken with a smartphone without endangering the technology. In addition to the solar filter, they recommend using the pro-mode of the camera app to set a low ISO value and short exposure time, thus avoiding overexposure and producing sharper and more detailed photos and videos. The solar eclipse will be visible as a partial event across the German-speaking region in the evening, starting around 7:22 p

After the solar eclipse, eye discomfort has raised concerns among observers. A growing number of individuals have reported pain or irritation in their eyes following the partial solar eclipse visible across German-speaking regions on Wednesday evening. Health experts warn that these symptoms could signal retinal damage, particularly if proper protective measures were not taken during observation. The warning comes amid heightened awareness of the risks associated with direct exposure to sunlight, even during a partial eclipse. The solar eclipse occurred around 7:22 p.m. local time, with the sun partially obscured over much of Central Europe. Observers noted the celestial event began shortly after sunset, with the sun positioned just 12 degrees above the horizon. Due to the nature of the partial eclipse, which did not fully block the sun’s light, all viewers were advised to take precautions. Despite this, many used smartphones or other devices to capture images of the event, often without adequate protection. This led to reports of eye strain, redness, and sensitivity, prompting calls for medical attention. Experts emphasize that prolonged viewing of the sun, even through non-specialized filters, can cause serious harm. The Federal Office for Radiation Protection issued guidelines stating that even indirect exposure can pose risks. It warned against using common sunglasses, welding goggles, or makeshift filters such as black film strips or folded blankets. These materials fail to block harmful ultraviolet and infrared rays, increasing the likelihood of retinal injury. Instead, certified solar viewing glasses, known as “SoFi” glasses, are recommended for safe observation. Smartphone users faced additional challenges. While some managed to capture clear images by adjusting camera settings, others inadvertently exposed their devices to damage. The Austrian Mobile Communications Association cautioned that focusing on the partially obscured sun for extended periods could destroy the sensitive image sensor in mobile phones. They urged users to employ solar filters specifically designed for cameras and to avoid relying on improvised solutions. Experts also suggested using the professional mode in smartphone camera apps, setting low ISO values and short exposure times to prevent overexposure and ensure clearer results. In response to the incident, several health professionals have called for greater public education on the dangers of unprotected solar viewing. Many who experienced discomfort have been advised to seek medical evaluation, especially if they notice persistent vision changes, blurred sight, or increased light sensitivity. Doctors stress that early detection is crucial, as delayed treatment can lead to permanent vision loss. Looking ahead, officials expect continued vigilance as similar astronomical events occur in the future. Public awareness campaigns are likely to intensify, particularly in areas where solar eclipses are more frequent. Meanwhile, manufacturers of optical equipment and smartphone accessories are being urged to provide clearer guidance on safe usage practices. As the region prepares for upcoming celestial events, the importance of adhering to safety protocols remains paramount.
