You’ve probably heard all the warnings, “never stare directly at a solar eclipse”. Although most people heed this advice, there are still things you need to be aware of before you view an eclipse. These helpful eclipse safety tips will make it easier to see the event with loved ones and ensure a safe and enjoyable experience.
Why Are Eclipses So Dangerous?
A solar eclipse is dangerous because you could damage your vision and not realize it. The eye’s retina does not feel sensations of pain. It’s not like looking at the sun directly, but harmful rays are still getting through. This is why it is so important to use some kind of solar filtering device when you view solar eclipses.
You Can Use Welder’s Glass
If you have a welder’s helmet with a shield you can use this to look at the solar eclipse. However, there are some things which friends or relatives may advise that you should not consider. For example:
* Smoked glass
* Tinted windows
* Standard sunglasses
* Photographic film – although a certain type of black and white exposed film can be used, unless you are an experienced photographer, it’s best not take chances with something as precious as your sight.
* Telescopes or cameras without proper filtering devices
Eclipse Safety is all about using the right kind of eye protection. Here is what you can safely use:
* Welder’s goggles
* Pinhole projector – make a simple projector with two surfaces. Cut a hole in one surface and use the other for the projector screen. People sometimes use cardboard boxes or paper plates to make homemade viewers like these.
* Telescope projector – shine the light from the large end to the small end of the telescope and project the image onto a white flat surface.
* Approved viewings – eclipse glasses and viewers are so inexpensive there is no need to try and make your own homemade device. It’s time consuming and for a dollar or two you can enjoy the eclipse in the most convenient manner. Make sure your viewers filter out infrared as well as ultraviolet light. Most people are aware of the dangers or UV light, but solar infrared light can also be damaging.
* Approved solar filters for telescopes and cameras
Don’t Forget the Kids
Kids sometimes don’t exercise proper judgment and should always be supervised during the entire eclipse event. Just telling them “not to look” is not good eclipse safety. For maximum fun, consider wacky and far out solar eclipse glasses for the children.
