Eclipse Safety
To have a safe and enjoyable eclipse viewing experience, please follow all NASA viewing guidelines for eye safety, including...
- It is never safe to look directly at the sun, even if the sun is partly obscured.
- When watching an eclipse, you must wear safe solar viewing glasses (eclipse glasses) at all times. ***Texclipse Music Festival is a verified and reputable seller.***

PLEASE BE WARY OF PRODUCTS THAT CLAIM TO BE SAFE BUT AREN'T. Be very careful and don't use any product unless claims of safety can be verified. For the 2017 eclipse, there were many reports of unsafe eclipse glasses being distributed as well as reports of counterfeit eclipse glasses printed with names of reputable manufacturers, including many that were sold on Amazon. Leading up to the 2017 eclipse, the American Astronomical Society provided guidance on how to tell if your eclipse glasses or viewers are safe. Before using your glasses or viewers, make sure that they are not damaged in any way (lenses shouldn't have scratches or wrinkles) and that you read all of the safety instructions that came with them. Children should always be supervised by a responsible adult when using eclipse safety glasses or viewers. Unless a product has been specifically designed for safe solar viewing and has been certified as meeting international standards for such products, it's best to assume that a device, method, or instrument is unsafe. Don't risk it! Unfortunately, the media doesn't always get it right and there is a great deal of misinformation in print and online about what's safe and what isn't. Items such as regular or polarized sunglasses, smoked glass, exposed film, medical x-rays, homemade filters, and many others are all unsafe. You can use welder's glass to view an eclipse, but it must be #14 welder's glass; any rating below #14 is not safe. It's also safe to view an eclipse using indirect methods, such as projecting an image of the eclipsed Sun onto a white screen. To make an indirect viewer, search online for "pinhole projector" and follow the instructions provided by a trusted organization like NASA.
If the eclipse will become total in your location (i.e., if you're in the narrow path of totality), don't remove your eclipse glasses until the very last bit of the Sun is gone and you can no longer see any light through them. Again, it's only safe to look with unprotected eyes when the Sun is 100 percent blocked by the Moon and only the soft wisps of the solar corona are visible. Once totality begins, it's important to know precisely when totality will be ending in your exact location so that you can once again put on your eclipse glasses before the first brightness of the exposed Sun is revealed. You should also allow for a very generous margin of error to ensure that you are no longer looking with unprotected eyes when totality ends (and keep in mind that your clock or watch may not be in sync with astronomical time!). Additionally, NASA advises that you should pay careful attention to the edge of the Moon opposite of where the Sun last appeared. When you start to notice a very slight crescent-shaped brightening, you’ll know that totality is coming to an end. This is your signal to look away or put your eclipse glasses back on before the first flash of exposed sunlight. As mentioned earlier, children should always be supervised by an adult who fully and clearly understands safe eclipse viewing procedures.
Note that attempting to view an eclipse using cameras, binoculars, telescopes, or other optical devices without proper solar filters is extremely hazardous and can permanently damage the eyes in an instant. These devices need specially designed solar filters that fit snugly on the front end (the Sun side) of the device. Never attempt to view an eclipse through an optical device using eclipse glasses or any type of filter that attaches to the viewing side (as opposed to the Sun side) of the instrument; the focused light will destroy the filter and enter and damage your eyes. Since viewing or photographing a solar eclipse with an optical device requires specialized equipment and knowledge, we recommend consulting with a qualified astronomer or just enjoying the eclipse with your own eyes (using safe eclipse viewing procedures, of course).For more information on how to safely view a solar eclipse, please see the excellent pages on viewing safety by the American Astronomical Society and NASA.
