How to Make a Pinhole Projector to View the Solar Eclipse
Are you concerned that your eclipse glasses may not give you enough protection or that your children might attempt to take them off or peer over and around them during Monday’s eclipse?
You would not be alone in those fears. Thankfully, a handy hack to make eclipse glasses safer has been making the media rounds. All you need is a paper plate, some tape, a pen, a pair of scissors and of course eclipse glasses. The alterations are simple according to Topeka, Kansas NBC affiliate KSNT.
Place the eclipse glasses in the center of the paper plate. Using the pen, trace around the eclipse glasses, drawing two diagonal lines from the bridge of the nose to the edge of the plate. Cut out this area and tape the glasses in place. The plate will stop any sunlight from getting to your eyes around the edges of the glasses. Curious kids trying to sneak a peek over the tops of their glasses should be thwarted, too.
Ophthalmologists stress that even minimal exposure to the sun’s harsh rays can create a lifetime of vision problems, including permanent retinal damage.
In a statement released last month, NASA called out potential counterfeit eclipse glasses that do not provide adequate protection and released a list of reputable providers and a guide to identifying if your glasses are legitimate.
They listed American Paper Optics, Rainbow Symphony, Thousand Oaks Optical and TSE 17 as reputable producers of eclipse glasses whose products can be trusted, and also recommend AstroSolar Silver/Gold lensed glasses by Baader Planetarium.
Safe eclipse glasses will be certified by ISO with a reference number of 12312-2 printed on them.
