All Thousand Oaks Optical products meet and exceed ISO 12312-2:201 5 (E)  requirements.  This means they've passed extensive testing for safe solar viewing.  Please read instructions fully before using. 

Viewer Cards
Thousand Oaks Optical Viewer cards can be used to view the sun at any time, whether there is an eclipse or not.  They may be looked through either side, however the black side is recommended to look through to avoid glare.
