Solar Eclipse Approaches - Learn Secure Viewing Methods Here

Preparing for a total solar eclipse can be a fascinating experience, but it's crucial to take some essential precautions to protect your eyes. While you might get the chance to witness one every 18 months or so, it's not something you'll want to miss because of a mishap.

So, here's the lowdown on observing this celestial wonder safely:

First things first, don't just sit back and stare at the sun during a total solar eclipse. You'll need some specialized gear to keep your peepers protected. Staring at the sun, even for a brief moment, can lead to significant and lasting damage to your vision.

Now, you might be wondering: why can't I just gaze up at the sun like I would any other time of year? Well, your eyes have those handy lenses that work like a magnifying glass, and when you look directly at the sun, the light gets concentrated right at the back of your eye – the retina. This concentrated light can cause burns or permanent damage to your macula, a critical area for vision.

If you decide to catch a glimpse of the solar eclipse, you'll want to invest in proper eye protection. Surgical ophthalmologist, Nicole Bajic, MD, suggests certain tips on how to choose the right equipment and avoid damaging your eyes:

What happens if you look at a solar eclipse without protection?

During a solar eclipse, the moon moves between the Earth and the sun, creating a shadow that travels over the Earth's surface. Depending on the kind of solar eclipse, the shadow can span up to 300 miles wide.

However, it's only safe to look directly at the sun during the brief moments of totality, when the sun is fully covered by the moon. Outside of these moments, you'll need to don your solar eclipse glasses or use specialized solar filters for your binoculars, telescopes, cameras, or phones to avoid causing lasting damage to your vision.

"You should check if you're in the path of totality, but it is only safe to look directly at the sun during a total solar eclipse when the sun is completely covered by the moon," remarks Dr. Bajic. "As the moon moves across the sun, if any part of the sun is exposed, you must be using specialized eye protection to prevent injury."

How to look at a solar eclipse

When choosing eyewear for a solar eclipse, it's important to look for certified options with a filter designation of ISO 12312-2. These specific glasses are thousands of times darker than regular sunglasses, blocking almost all visible light, ultraviolet, and infrared rays. They should be worn whenever looking directly at the sun, for any amount of time.

In the path of totality, these solar eclipse glasses should be worn before and after totality. It's important to remove your solar eclipse glasses immediately when the sun begins to peek through again – even if it's just a sliver of sunlight. During the brief moments of totality, you can safely remove the glasses to see the breathtaking sight of the moon completely covering the sun.

When using specialized solar filters for your optical devices, make sure to obtain expert advice from a local astronomer for proper installation and use. Do not rely solely on eclipse glasses if using these devices, as the concentrated sunlight can still cause eye or sensor damage.

A pinhole projection method can also be used to view the solar eclipse indirectly. To create one, use a colander, perforated spoon, or interlaced fingers to create a pinhole that projects an image of the partial phases of the solar eclipse onto a white surface. Just remember not to stare directly at the sun through the colander or other device.

In addition to protecting your eyes during the eclipse, don't forget to wear sunscreen daily, as the sun's rays have a direct impact on the health of your skin. Enjoy the solar eclipse knowing you're taking steps to ensure a safe and memorable experience for you and your vision!
