How to Watch Without Risk

Your eyes are your most precious asset. Here is the science of safety.

The ISO 12312-2 Standard of  Sol & Salvo glasses are not toys; they are scientific instruments. They contain a specialized polymer film infused with carbon particles that filter out 100% of harmful ultraviolet and infrared rays.
 
Myth: "I can stack two pairs of sunglasses." -> FACT: No. This is still thousands of times too bright and will burn your retinas.
Myth: "I can use X-Ray film or smoked glass." -> FACT: Dangerous. These materials let invisible IR radiation through, cooking your eye without you feeling pain.

User Instructions

  • Inspect: Hold glasses to a light. If you see pinholes or scratches, discard them.

  • Wear: Place them on your face before looking up.

  • Observe: Enjoy the view! For comfort, take frequent breaks.

         Do not view continuously for more than 3 minutes.

  • Remove: Look down or away from the sun before taking them off.

  • The Golden Rule: If any part of the sun is visible (even 1%), you must wear the glasses!!!

The Totality Experience witnessing a total eclipse is a unique sensory experience.

As totality approaches:  The temperature drops suddenly.
The sky darkens to a deep twilight. Stars and planets become visible in broad daylight.
Nature reacts: birds go silent and retreat, as if night has fallen...

The different types of eclipses OR Why not all eclipses are the same?

The distance from the Moon to Earth and the exact alignment determine the type of visual spectacle:

  • Total Solar Eclipse: The "king" of eclipses. The Moon covers the entirety of the solar disk. Day turns into night for brief moments, allowing the solar corona (the Sun's outer atmosphere)—usually outshined by intense light—to be seen.

 

  • Partial Solar Eclipse: The Moon "takes a bite" out of only a part of the Sun. The visual result resembles a glowing crescent.

 

  • Annular Solar Eclipse: Occurs when the Moon is farther from Earth in its orbit and appears smaller in the sky. It cannot cover the Sun completely, leaving a spectacular "ring of fire" visible around the lunar silhouette.​

 

  • ​Hybrid Solar Eclipse: The rarest of all. Due to the Earth's curvature, the eclipse can appear total in some locations and annular in others during the same event.

The Frequency Mystery: Why Don't They Happen Every Month?

The answer lies in the tilt. The Moon's orbit is tilted by about 5 degrees relative to Earth's orbit around the Sun. During most New Moons, the Moon's shadow passes too "high" or "low" and misses the Earth.Eclipses only occur during so-called "eclipse seasons," which happen approximately twice a year, when the orbital planes intersect.
