how to make a solar filter glass to see the solar eclipse
Answers
Answer:
If you are not the DIY type, the American Astronomical Society has compiled a list of vendors where you can buy safe eclipse glasses. Use protective gear. NASA recommends welder's glasses rated 14 or higher. These can be found at your local welding supply store.

Answer:
Step 1: Gather Your Materials
Here’s what you’ll need to create your own pair of solar eclipse glasses:
A large piece of poster board or card stock.
A template for your glasses (draw an outline or print out a template).
A solar filter.
A roll of blue painter’s tape.
Scissors.
A pen.
If you have a pair of recycled 3D glasses on hand, you’re in luck! You can skip the poster board and template for an easy alternative.
Step 2: Prep Your Frames
If you’re making your own frames from scratch, start by laying out poster board or card stock on a flat surface. Next, draw your outline or place your printed template on top. Once your paper is prepped, use your scissors to cut out the frames. You should have one rectangular piece with cutouts for your nose and eyes, as well as two separate handles for your ears.
If you’re repurposing an old pair of 3D glasses, simply pop out the old lenses and you’re ready for the next step.
Step 3: Insert Your Solar Filter Lenses
Next, measure and cut the solar film so that it completely covers the eye holes of your glasses. Make sure not to puncture or scratch the film while handling it because any deformity can diminish its protective quality. Also, be sure not to cut the film too close to size; you want there to be a decent overlap so that no light can leak through the edges of the eye holes.
Step 4: Secure With Tape
Once your solar film is in place, secure it to your frames of choice with your roll of blue painter’s tape. If you’re making your solar eclipse glasses out of poster board or card stock, it’s time to tape the earpieces in place as well.
Step 5: Go for a Test Run
To determine the safety of your glasses, it’s time for a test run! Go into a dark room, put the glasses on, and have a friend shine a flashlight in your direction. If any of the bright light comes through (without the yellow/orange hue), you have a leak.
If that happens, it’s better to find out now than when you’re viewing the actual eclipse. Simply follow the steps laid out above again, using a new piece of solar film. If all goes well in your test run, then you’re ready for the real deal!
