On Monday, August 21, 2017, a solar eclipse will occur across the United States. 

(See details at NASA's solar eclipse page:  


For those of you that will be observing the eclipse, it is critical to remember that it is NOT safe to directly look at the eclipse without proper eye protection, not even for a few seconds. Temporary, and sometimes permanent, loss of vision may occur if individuals fail to take proper safety precautions.  This damage will occur painlessly since the cells in the retina that are damaged during the eclipse do not have any pain receptors.  


Some key safety tip are listed below:


1.  Do not directly view the eclipse without ISO (International Organization of Standardizations) certified eye protection.


2.  NASA has released a list of vendors that are approved.  All approved glasses will be stamped with both the ISO approved symbol as well as the manufacturer's name:

                a. American Paper Optics (

                b.  Rainbow Symphony (Eclipse shades)

                c.  Thousand Oaks Optical (Silver-Black Polymer and SolarLite)

                d. TSE 17

                e.  Baader Planetarium (AstroSolar Silver/Gold Film)


3.  Be sure to inspect approved glasses to ensure that they are ISO and manufacturer stamped and inspect the lenses looking for any scratches or defects in the lenses.  Do not use them if they are scratched, wrinkled or more than three years old.


4.  NASA has found that several vendors NOT listed above are selling eclipse glasses that contain the ISO stamp even though they do NOT meet the required safety standard for direct viewing of the eclipse.  Only purchase from the NASA approved vendors.


5.  It is NOT safe to view the eclipse directly with any of the following: 

                a. Regular sunglasses, no matter how dark they are and no matter how many pairs you put together.

                b. Through any binoculars, telescopes or cameras (even cell phone cameras) without certified lenses that are approved and manufactured specifically for that device.  

                c.  It is NOT safe to view through these devices even if you are wearing approved direct viewing eclipse glasses.  

                d.  Approved direct viewing eclipse glasses are only safe to be used for direct viewing without looking through binoculars, telescopes or cameras.
