Eclipse Glasses: Essential for Safe Sun Viewing
Understanding the Difference Between Regular Sunglasses and Eclipse Glasses
Eclipse Glasses: Specialized Protection for Solar Observation
Eclipse glasses are not your average sunglasses. They are specially designed to block harmful ultraviolet (UV) and infrared (IR) light emitted by the sun, making them essential for safe solar observation during celestial events like solar eclipses.
ISO Certification and Damage Assessment
Legitimate eclipse glasses meet rigorous standards and bear the ISO 12312-2 certification. Before using, inspect the glasses for any cracks, scratches, or damage. Damaged glasses can compromise protection and should not be used.
Regular Sunglasses: Not Safe for Sun Observation
Ordinary sunglasses, regardless of their darkness, are not safe for viewing the sun. They do not effectively block harmful UV and IR radiation, which can damage your eyesight.
Sun Observation with Eclipse Glasses
To safely observe the sun with eclipse glasses, follow these steps:
- Cover one eye with an eclipse glass.
- Hold your other hand over the eclipse glass, forming a "waffle" pattern with your fingers.
- Position your hand slightly above your eyes, at a 90-degree angle to the sun.
- Allow sunlight to filter through the waffle pattern and onto the eclipse glass.
Conclusion
Eclipse glasses are an essential tool for safe sun viewing. They provide unparalleled protection against harmful UV and IR radiation, while regular sunglasses do not. By following the proper usage instructions, you can enjoy celestial events like solar eclipses without compromising your eyesight.
