On the day of a solar eclipse, millions of people around the world gather to witness this awe-inspiring natural phenomenon. However, looking directly at the sun during an eclipse can be extremely harmful to the eyes. This is where eclipse glasses come in.

What are Eclipse Glasses

Eclipse glasses are specially designed eyewear that allows viewers to safely observe solar eclipses. These glasses are made with a special solar filter that blocks out harmful ultraviolet (UV) and infrared (IR) radiation while still allowing you to see the sun.

How Do Eclipse Glasses Work

Eclipse glasses work by reducing the amount of visible light that reaches your eyes. The special solar filter in the glasses blocks out the harmful radiation from the sun, protecting your eyes from damage.

Why are Eclipse Glasses Important

Looking directly at the sun, even during an eclipse, can cause serious and permanent damage to your eyes. Without proper eye protection, you risk burning the sensitive tissues in your eyes and potentially causing blindness.

Case Studies

In 2017, during the total solar eclipse that swept across the United States, there were reports of people experiencing eye damage from looking at the sun without proper protection. However, those who used eclipse glasses were able to safely observe the eclipse without any harm to their eyes.


According to the American Astronomical Society, over 200 million people viewed the 2017 solar eclipse, with many using eclipse glasses to protect their eyes. This demonstrates the importance of using proper eye protection during celestial events.


Eclipse glasses play a crucial role in ensuring the safety of your eyes during solar eclipses. By using these specially designed eyewear, you can enjoy the wonders of the universe without risking damage to your vision.
