When it comes to safely observing a solar eclipse, having the right equipment is crucial. Two popular options for eclipse enthusiasts are the Rainbow Symphony Eclipse Viewing Glasses and the Celestron EclipSmart Solar Glasses. In this comparison, we'll delve into the features, benefits, and differences between these two types of eclipse viewing glasses.

Safety Certification

Both the Rainbow Symphony Eclipse Viewing Glasses and the Celestron EclipSmart Solar Glasses meet the international safety standard for solar viewers, ISO 12312-2. This certification ensures that the glasses provide adequate protection for your eyes during a solar eclipse. The ISO 12312-2 standard requires that solar viewers block out at least 99.999% of both UVA and UVB radiation, as well as reduce the intensity of visible light to a safe level.

Optical Quality

The Rainbow Symphony Eclipse Viewing Glasses feature polycarbonate lenses with a scratch-resistant coating, providing clear and sharp images of the eclipse. The Celestron EclipSmart Solar Glasses, on the other hand, boast high-quality, optical-grade polymer lenses that offer excellent clarity and contrast. Both options provide a comfortable and immersive viewing experience.

Field of View

The Rainbow Symphony Eclipse Viewing Glasses have a slightly wider field of view (about 25°) compared to the Celestron EclipSmart Solar Glasses (about 20°). This means that you can see more of the eclipse's surroundings with the Rainbow Symphony glasses. However, the Celestron EclipSmart Solar Glasses have a more compact design, making them easier to store and transport.

Comfort and Ergonomics

Both pairs of eclipse viewing glasses are designed for comfort and ergonomics. The Rainbow Symphony Eclipse Viewing Glasses have adjustable temples and a soft, rubberized nose piece, ensuring a secure fit for various face shapes and sizes. The Celestron EclipSmart Solar Glasses feature a similar design, with adjustable temples and a contoured nose piece for added comfort.

Additional Features

The Celestron EclipSmart Solar Glasses come with a few extra features that set them apart from the Rainbow Symphony Eclipse Viewing Glasses. For example, they have a built-in filter that allows you to observe the eclipse in both solar and lunar modes. Additionally, the Celestron glasses include a carrying case and a neck strap for convenient storage and transport.

Price

The price point of these two types of eclipse viewing glasses differs slightly. The Rainbow Symphony Eclipse Viewing Glasses are generally priced lower, making them a more affordable option for those on a budget. The Celestron EclipSmart Solar Glasses, with their additional features and high-quality construction, tend to be pricier.

Conclusion

In conclusion, both the Rainbow Symphony Eclipse Viewing Glasses and the Celestron EclipSmart Solar Glasses are excellent options for safe and enjoyable eclipse viewing. When choosing between these two types of eclipse viewing glasses, consider your priorities: if you're looking for a more affordable option with a wider field of view, the Rainbow Symphony glasses might be the better choice. If you prefer a more compact design with additional features and high-quality optics, the Celestron EclipSmart Solar Glasses are worth the investment. Ultimately, both options will provide you with a safe and memorable eclipse viewing experience, making them great choices for anyone looking to witness this rare celestial event.
