Viewing the 2025 Total Eclipse Safely
Witnessing a total solar eclipse is a breathtaking experience, but it’s crucial to prioritize eye safety. Looking directly at the sun, even for a short time, can cause serious and permanent eye damage, including blindness. This is true for all phases of a partial eclipse, as well as the moments before and after totality during a total eclipse. Only during the brief period of totality, when the moon completely blocks the sun’s disk, is it safe to view the eclipse without eye protection.
The intense brightness of the sun, even during a partial eclipse, emits harmful ultraviolet and infrared radiation that can damage the retina, the light-sensitive tissue at the back of the eye. This damage can occur without any immediate pain or discomfort, making safe viewing practices absolutely essential.
Safe Viewing Methods for Solar Eclipses
Safe solar viewing requires the use of certified eclipse glasses or other specialized solar filters. These filters are designed to block out harmful levels of ultraviolet and infrared radiation, allowing you to safely observe the sun. Improper filters, such as homemade devices or sunglasses, even very dark ones, are insufficient and pose significant risks. Only ISO 12312-2 certified eclipse glasses should be used. These glasses will have this certification clearly marked on them.
It is also possible to indirectly view the eclipse using pinhole projection. This involves creating a small hole in a piece of cardboard and projecting the sun’s image onto another surface, such as another piece of cardboard. This method safely projects a smaller, inverted image of the sun. Ensure that you are not looking directly at the sun, even while setting up your pinhole projector.
Safety Differences Between Partial and Total Eclipse Phases
During a partial solar eclipse, the sun is only partially obscured by the moon. At no point during a partial eclipse is it safe to look directly at the sun without proper eye protection. The sun’s intense radiation remains a danger throughout the entire partial phase.
Only during the brief period of totality in a total solar eclipse is it safe to remove your certified eclipse glasses. Totality occurs when the moon completely covers the sun’s disk, creating a dramatic darkening of the sky. This period typically lasts only a few minutes. As soon as the sun begins to reappear from behind the moon, immediately put your eclipse glasses back on. Failure to do so will expose your eyes to harmful radiation. Observing the partial phases before and after totality requires certified eclipse glasses or other safe viewing methods at all times.
