The Great American Solar Eclipse 2017 is just around the corner. Are you ready?
Here are some quick tips you will need to know to insure that your family and friends can enjoy this “once in a lifetime” event and protect their vision at the same time.
Bonnie Tyler will sing “Total Eclipse of the Sun” while aboard a Royal Caribbean cruise ship. The ship leaves from Miami and will be situated within the path of totality as it leaves the coast of South Carolina.
The path of totality starts in Oregon and moves eastward through South Carolina. The path of totality is about 70 miles wide and will be the only area in the United States where a total eclipse of the sun will be experienced.
For 2 minutes and 4o seconds, those in the path of totality will essentially experience total darkness as the sun is completely blocked by the moon.
Those not within this 11 state swath will experience a partial eclipse.
Sunglasses offer no protection from the damaging UV light of the sun. Only ISO certified filters offer protection from direct sunlight.
ISO 12312-2 filters are used in “eclipse glasses” and solar viewers. These filters are strong enough to allow direct visualization of the eclipse.
ISO filters are the only way to directly visualize the eclipse without risk of solar retinopathy. Solar retinopathy is caused by the sun’s intense UV radiation causing damage to the rods and cones of your retina.
While gazing too long at the sun, UV damage to your retina is painless. Symptoms of solar retinopathy include:
Solar retinopathy can be permanent. Blindness can occur.
If you can not find certified ISO eclipse glasses, consider constructing your own pinhole camera.
Using simple materials found around the house (aluminum foil, white paper, tape, scissors), construct an easy to build pinhole camera.
A pinhole camera avoids direct sun light and, therefore, avoids any chance of developing permanent vision loss from solar retinopathy.
All the best,
