If you're planning to watch the solar eclipse on August 12, you'll need ISO certified eclipse glasses to view it safely. Aldi is currently offering The World of Calgary eclipse glasses at half price for just €1.49, making it an affordable way to protect your eyes during this celestial event.
Why You Need Certified Eclipse Glasses
Viewing a solar eclipse without proper protection can cause serious eye damage, including permanent vision loss. Regular sunglasses are not sufficient—they do not filter out the intense infrared and ultraviolet radiation that can harm your retina.
Eclipse glasses must meet the ISO 12312-2:2015 safety standard, which ensures they block out harmful rays while allowing you to see the eclipse safely. Always check that your glasses are undamaged and certified before use.

Aldi's Half-Price Deal on Eclipse Glasses
Aldi is selling The World of Calgary eclipse glasses for only €1.49, which is half the regular price. This offer is available while stocks last, so if you have an Aldi store nearby, it's worth checking out soon.
The glasses are ISO certified, so you can trust them to provide adequate protection. However, always inspect them for any scratches or damage before using them to view the eclipse.
Alternatives If You Can't Get to Aldi
If you don't have an Aldi nearby or they've sold out, Amazon offers several options for certified eclipse glasses. For example, EclipseSpecs provides a two-pack of ISO certified glasses, and Medical King offers a two-pack that includes smartphone lenses and an observation guide.
These alternatives are slightly more expensive but ensure you're prepared for the eclipse. Remember to verify the ISO certification before purchasing.
