How to protect our eyes from damage as we watch the eclipse?

[Wiota]

Do not stare directly at the sun at any time as this could cause permanent damage to your eyes, in particular the retina. Remember the only way to safely view the uneclipsed or partially eclipsed sun, is to project or filter the sun's rays. Even when filtering the sun's rays, wear a pair of sunglasses too for additional protection and make sure they offer 100% UV protection. For a quick and easy way to filter the sun's rays, you can make your own pinhole projector, which can also double as a fun activity for those with children.

the safest way to view the eclipse is to make a small hole in a card, hold it up to the sun and project the image on to the ground or a second piece of white card. People shouldn't view the sun directly through the hole. The eclipse can also be safely viewed through appropriate filters called eclipse glasses, which are available through astronomy clubs. It is essential that these glasses have no scratches or damage to the lenses.High protection welding goggles are also suitable (filter 14 or over), whereas sunglasses or 3D viewing glasses are not.

Never try to look directly at the sun unless using a store bought filter specifically designed for that. Stores that sell telescopes should also carry them. The best way is to look at a projection of the sun. Get a shoebox and poke a hole in one end. The hole should not be too big. Bigger than a pin hole but still pretty small. Place a piece of paper at the other end of the box. Point the end with the hole at the sun and watch the projection on the paper. Never look directly at the sun, even during an eclipse.
