Are Nasa Glasses Safe For Watching The Eclipse

The eclipse glasses arrived on time made by one of the manufacturers approved by NASA for manufacture of glasses for eclipse viewing.

Item was as described and arrived on time. They look similar to solar eclipse glasses I have from NASA.

There are great eclipse-watching glasses

B&H was the only way left to get eclipse glasses in time. I got them early enough to distribute to family members. The glasses were NASA approved and worked fine.

Highly recommend these glasses for eclipse viewing. Sturdy and safe.

It worked well for the eclipse viewing I did. Seemed safe and made watching the event possible.

The solar glasses fit perfectly over my prescription glasses and make viewing a solar eclipse safe.

The glasses were excellent. They provided a clear safe view of the sun and eclipse.

This is a wonderful tool for solar viewing. We ordered four, one for each of us, for the 2017 eclipse. Using these magnified the sun ten times, to where the sunspots were easily visible. These are so much better than the glasses and made watching the eclipse more enjoyable. There seems to be some quality control problems though. Two of the four were perfect. One was distinctly lighter than the other three which caused a concern (there are three darkening filters inside each tube -- makes one wonder if one is missing in one). One arrived optically unaligned. With no time for exchange due to the nearness of the eclipse, we unscrewed the viewing lenses on the unaligned one to discover that the inside elements were at two different depths in the tube. It explained the problem. These are slid in and held in place by friction. This binocular arrived separately so its package may have been dropped in shipment. By lightly tapping the binocular against a padded hard surface, we were able to move both lenses forward. Then we cut a piece of soft lens cloth to cover the top of a nickel to push each lens back into the tube at the same depth. We added a nickel at a time until it focused mid-point in the binocular's center adjustment. We then reset the filters and screwed on the lens cap and it worked perfectly. We never unscrewed the cover for the less darkened binocular because we read that they are nitrogen filled. It works fine but it makes one wonder if it is working on two darkened filters rather than three. The cost is very reasonable and it made watching the eclipse more enjoyable. In the end we never used our glasses, only these.

These glasses were great for watching the 2017 solar eclipse. They were out of stock when I ordered them but B&H shipped them out exactly on the date they said they would and they arrived in plenty of time for the eclipse. Thank you for the great service!
