Make a Projector to Safely See a Solar Eclipse
A total solar eclipse is one of the most awe-inspiring events in nature, but astronomers and ophthalmologists warn that looking at the sun without solar eclipse glasses or other protection can damage your eyes and cause permanent blindness. Totality, the brief period when the moon completely covers the sun, is the only safe time to watch with the naked eye. Lasting from seconds to a maximum of 7. The sun is basically a huge, continuous thermonuclear explosion, which produces intense radiation across the spectrum from infrared to ultraviolet light and beyond.
Infrared light is absorbed by many materials and is readily converted to heat, while ultraviolet light is the source of sunburn. Headaches and temporary distortion of vision are only the mildest effects from exposure to bright sunlight. According to the Cleveland Clinic, ultraviolet radiation can cause a number of eye disorders, including macular degeneration, solar retinitis and corneal dystrophies. Moreover, the effects are cumulative, so looking at the sun twice results in two times the damage compared to looking at it once, even if viewed on different days.
Although people have a natural aversion to extremely bright light, the temptation to gaze at the sun during a solar eclipse can be overwhelming, leading to lapses of good judgement. The darkness that accompanies an eclipse can override the reflex to squint and avert sight, increasing the amount of intense light striking the retina and making eye damage more likely. Because of its intensity, viewing even a small slice of the sun can be dangerous. If you want to watch a solar eclipse, use eye protection that filters the spectrum from infrared to ultraviolet.
You can use welder's goggles of Shade 12 or higher. Even better, use solar eclipse glasses that are specially made for viewing the sun. Make sure the lenses of your solar eclipse glasses are not torn, scratched or punctured. If the lenses are damaged or are coming loose from the frames, throw the glasses away. Because their larger optics collect and concentrate much more light than the lens of the eye alone, do not look at the sun through unfiltered telescopes, binoculars or photographic lenses — eclipse glasses do not protect your sight in this situation.
From start to finish a solar eclipse lasts several hours and you can watch all phases safely with a projector made from two pieces of cardboard. Punch a pinhole in one board and face it toward the sun. Using this simple method you can witness a rare astronomical event while also protecting your sight.
