Solar eclipse glasses: Why do you need them and where can you buy them? | Top Stories
On August 11, people around the world will be treated to a partial solar eclipse.
But looking directly at the Sun can damage your retinas, causing permanent damage to your eyesight.
Provided there’s not complete cloud cover – in which case you won’t see much at all – you need to be prepared to look a little silly if you want to watch the spectacular event.
Good solar eclipse glasses filter out all of the harmful ultraviolet and infrared light and almost all of the intense visible light to allow you to view the eclipse safely.
If you can’t find CE-approved glasses, don’t rely on regular sunglasses – they won’t protect you.
Here are some of the best safety approved glasses:
Solar Eclipse Viewer by Thousand Oaks Optical
One of the best options is the Solar Eclipse Viewer by Thousand Oaks Optical.
The card-shaped device has a small filter window in the middle, allowing you to safely look at the partial eclipse.
The sun will appear in a natural orange colour when viewed through the filter.

Black Polymer Film Solar Filter Glasses by Thousand Oaks Optical
If you’re planning a viewing party, then Thousand Oaks Optical’s black polymer film solar filter glasses, which come in a pack of 25, could be a great option.
Like the Solar Eclipse Viewer, the glasses have black polymer film filters that allow you to look directly at the sun.
