Planning to watch the eclipse? Read this first

On Monday, August 21, 2017, sky-gazers across the country will watch the solar eclipse. If you’re planning to watch, you’ll need to use eclipse glasses or hand-held solar viewers. Be sure to get the kind that actually protects your eyes. Eclipse glasses

Start by making sure that the glasses or viewers you’re considering have the manufacturer’s name and address printed somewhere on the product, and are certified as safe. The certification means the glasses and solar viewers have met an international safety standard and are safe for your eyes. Only consider products marked with ISO 12312-2, which means that the product has met the international safety standard. Check out this list from the American Astronomical Society of brands that meet the international safety standard.

What else do you need to know to watch the eclipse safely?

  • Be sure your glasses or viewers are new: glasses that are more than 3 years old, or are wrinkled or scratched, won’t protect your eyes.
  • Read – and follow – the instructions carefully. Don’t use homemade filters or ordinary sunglasses.
  • Never look directly at the sun without eclipse glasses or solar viewers that are certified as safe. (Again, look for ISO 12312-2 to be printed on the product.) It can lead to serious injury.
  • Don’t look at the uneclipsed or partially eclipsed sun through an unfiltered camera, telescope, binoculars, or other optical device – even using your eclipse glasses or viewer. Those optical devices concentrate the solar rays, will damage your eclipse glasses or viewer, and seriously injure your eyes.

This rare event will be exciting – and even better when you view the eclipse safely. Check out NASA’s Eclipse 101 for even more on the eclipse.

Thank you for all your helpful advice I wouldn't have otherwise known. I'll enjoy the eclipse more knowing my family is safe from harm. Can I find these glasses any place special or just the regular stores?

What glasses?

Can you please provide information regarding vendors that have the glasses available in the area or can mail.?

Can you give us some local places to obtain these glasses?

where can one purchase the glasses?

ISO standards for eclipse glasses

Hello I was wondering where would u be able to purchase the glasses I'm not sure but I hope the user name is correct,wondering if there's a way for me to get a response I wanted to do it with my 10 year old daughter but it might be a good suggest to annouce this publicly because if I never would have seen or looked at this email, I assumed that it was 100 % safe to go out and view the eclipse with no eye protection but I hope that I get a response & I'm marking this on my calendar thank you have a BLESS & WONDERFUL EVENING

where can we get them in the Burien area?

Great information! This type information should be part of daily news to make sure everyone is informed properly.

In NY Lowes, Target, and Home Depot are selling them. Which probably means Ace Hardware and other big distributors are as well.

What's wrong with eclipse glasses that are more than 3 years old if they have been kept safe? There's nothing about them that erodes, right? Have standards changed? This would mean that someone who used the older version in the past injured their eyes in doing so.

You're right. This is from the NASA article referenced in this post:
Some glasses/viewers are printed with warnings stating that you shouldn't look through them for more than 3 minutes at a time and that you should discard them if they are more than 3 years old. Such warnings are outdated and do not apply to eclipse viewers compliant with the ISO 12312-2 standard adopted in 2015.
