Not all solar viewing glasses are created equal! Many glasses use a cheaper filter that severely reduces the brightness of the image of the Sun. Our solar viewing glasses have an optical density of 5 (or greater) and are CE certified. Meaning they meet the transmission requirements of the European standard for eye protection (EN 169/1992), yet still allow enough light through to see the Sun clearly. The pictures below show the difference.

With our Solar viewing glasses you can view solar events (Sunspots, eclipses, and transits of Mercury and Venus) with absolute safety. However, we do not recommend that you use solar glasses with cameras, binoculars, or telescopes.
