Quick Action Guide
🚨 NEVER DO THIS:
- • Look directly at the sun without protection
- • Use regular sunglasses, even very dark ones
- • Use homemade filters (exposed film, smoked glass, etc.)
- • Use binoculars or telescopes without proper filters
- • Look through camera, phone, or tablet
✅ SAFE OPTIONS:
- • Use ISO 12312-2 certified eclipse glasses
- • Make a pinhole projector
- • Watch online or on TV
- • Attend viewing parties at museums or planetariums
📞 CALL DOCTOR IF:
- • Child has eye discomfort after viewing
- • Headache or vision problems develop
- • Blurry vision or blind spots appear
Why Is It Dangerous to Watch a Solar Eclipse Without Eye Protection?
Looking at the sun without the right protection can burn a part of the eye called the retina in just a few seconds. And because it's not painful, kids don't know their eyes are being harmed. The sun's powerful rays can cause permanent damage even during an eclipse when the sun appears less bright.
Symptoms May Take Hours to Appear
When the retina is damaged, symptoms can take hours to develop. Mild symptoms may include:
- • Discomfort when looking at bright lights
- • Headaches
More Serious Symptoms
The longer someone looks at the eclipse without proper protection, the more serious the symptoms can be:
- • Blurry vision
- • Blind spots
- • Trouble seeing colors or shapes
Most of the time, symptoms go away on their own after a while. But it can take months. And sometimes they don't fully go away. If kids have any eye problems after viewing an eclipse, they should see an eye doctor immediately.
Safety Tips for Watching a Solar Eclipse
1. Wear Eclipse Glasses or Use a Handheld Solar Viewer
These have lenses that are thousands of times darker than those of regular sunglasses. Regular sunglasses won't protect a child's eyes during a solar eclipse.
The American Astronomical Society gives tips on using these special glasses and viewers safely. Choose ones that meet an eye safety standard called ISO 12312-2. Fake ones won't give enough protection. Don't use glasses or viewers if they're damaged.
2. Use a Pinhole Projector
This is a way to see the eclipse on another surface, like an index card or cardboard box by using a small hole. NASA has step-by-step instructions for making a safe pinhole projector that allows viewing the eclipse indirectly without any risk to the eyes.
3. Watch It Online or on TV
This is the safest option for children. Many websites, NASA's website, and television channels provide live coverage of solar eclipses with expert commentary. This completely eliminates any risk of eye damage.
4. Attend Viewing Parties
Places like museums, planetariums, and science centers may have solar eclipse viewing parties and offer proper eye protection. They often provide certified eclipse glasses and have experts on hand to ensure safe viewing.
Is It Safe to Take Pictures of a Solar Eclipse or Record It?
⚠️ It's NOT safe to photograph or record a solar eclipse with standard equipment.
Eclipse glasses and solar viewers shouldn't be used with a camera (or binoculars or a telescope). The lenses of these items can focus the sun's rays too strongly and harm your child's eyes. The intense light can cause instant and permanent eye damage.
Professional Photography
Professional photographers use special filters with their cameras that let them take images and videos safely. These filters are specifically designed for solar photography and block harmful radiation. For most families, it's best to simply watch and enjoy the eclipse safely rather than attempt to photograph it.
What Other Safety Tips Should We Follow?
If kids will be out in the sun during a solar eclipse, you'll want to protect their skin as well as their eyes.
- • Use sunscreen: Apply broad-spectrum sunscreen with at least SPF 30
- • Wear a hat: Broad-brimmed hats provide additional protection
- • Wear protective clothing: Long-sleeve shirts and pants help shield skin from UV rays
- • Stay hydrated: Bring water, especially for outdoor viewing events
What About Lunar Eclipses?
A type of eclipse that's safer to watch is a lunar eclipse. This is when the moon passes into the earth's shadow. Since the moon doesn't make its own light, there's no need to protect eyes or skin. You can watch a lunar eclipse safely without special eyewear - it's completely safe to view with the naked eye! Lunar eclipses also last much longer than solar eclipses, making them easier to observe.
Frequently Asked Questions
Q: Can I use sunglasses to view a solar eclipse?
A: No! Regular sunglasses, even very dark ones, do not provide adequate protection for viewing a solar eclipse. They are not designed to filter out the sun's harmful rays. Only ISO 12312-2 certified eclipse glasses are safe for direct viewing.
Q: How do I know if eclipse glasses are safe?
A: Look for the ISO 12312-2 standard label on the glasses. This is an international safety standard for filters used for direct observation of the sun. Make sure the glasses aren't scratched, torn, or damaged in any way. Also, buy from reputable suppliers like science museums or authorized dealers.
Q: Can my child view the eclipse through a pinhole?
A: A pinhole projector projects the eclipse onto a surface (like paper or cardboard), so your child looks at the projection, not at the sun directly. This is a safe viewing method. However, make sure your child understands not to look through the pinhole at the sun.
Q: What if my child accidentally looks at the sun?
A: If your child looks at the sun without protection during an eclipse, monitor them closely for symptoms like eye pain, blurred vision, or headaches. These may not appear immediately. If symptoms develop, contact an eye doctor right away. Most children recover, but some damage can be permanent.
Q: Is it safe during totality?
A: During the brief period of totality (when the moon completely covers the sun), it is safe to view without eclipse glasses. However, this moment only lasts seconds or minutes, and you must put the glasses back on immediately as the sun reappears. NEVER look at the partial eclipse without protection.
Q: Can I watch the eclipse through a tinted window?
A: No! Car windows, dark windows, or tinted glass do not provide adequate protection. The sun's rays are still dangerous when viewed through such materials. Always use properly certified eclipse glasses or use a pinhole projector method.

Solar retinopathy (damage to the retina from staring at the sun) can cause permanent vision loss. Always use certified ISO 12312-2 eclipse glasses or other safe viewing methods. If your child experiences any eye problems after viewing a solar eclipse, seek immediate medical attention from an eye care professional.
