Watching solar eclipse without protection puts eyes at risk for thermal burns

The intense solar radiation coming from the bright crescent during the solar eclipse Aug. 21 can cause long-term or permanent blindness.

The American Astronomical Society recommends proper eye protection to prevent eclipse blindness.

Without it, the sunlight can trigger a series of chemical reactions in the retina, a layer at the back of the eyeball containing cells that are sensitive to light.

Observing the eclipse with a camera, a binocular or a telescope also has its risks. NASA experts suggest users to practice before the event to make sure that no mistakes are made.

Here are some tips and reminders to be prepared:

- The filters need to be in good condition. Look out for scratches, bubbles or dents.

- Make sure your handheld viewer covers both eyes. 

- Sunglasses are not enough protection. 

The goggles must be made out of polyester film coated in aluminum or black polymer.
