Forget Sunglasses: How to Keep Your Eyes Safe During the Solar Eclipse<\/span><\/strong><\/span><\/h2>\n

Forget Sunglasses: How to Keep Your Eyes Safe During the Solar Eclipse:- The total solar eclipse is coming, and as the excitement builds, so does the worry that it will leave behind a nation of eye problems.<\/span><\/p>\n

On Aug. 21, the spectacular sight of the moon covering the sun will be visible across North America for the first time in almost a century.<\/span><\/p>\n

We\u2019ll all be tempted to gaze up at the sky, but many people don\u2019t realize they can get hurt by staring directly at the sun without the proper protection, said Dr. Russell N. Van Gelder, professor of ophthalmology at the University of Washington School of Medicine.<\/span><\/p>\n

\u201cThe danger is real for permanent vision loss,\u201d Van Gelder, a clinical spokesman for the American Academy of Ophthalmology, told TODAY.<\/span><\/p>\n

\u201cIt\u2019s a big deal for us. We don\u2019t have a lot of public health issues in ophthalmology where we\u2019re really worried about things that threaten the eye health of the population \u2026 But this is an event that really hundreds of millions of people are going to be exposed to.\u201d<\/span><\/p>\n

Even if one-tenth of 1 percent of people ignore the warnings, there could be thousands of Americans who lose some vision, he noted. Children are at highest risk.<\/span><\/p>\n

Here\u2019s what you need to know:<\/span><\/p>\n

WHY YOUR EYES ARE IN DANGER<\/span><\/p>\n

You may remember taking a magnifying glass outside as a kid on a sunny day and burning a hole in a leaf or starting a small fire. It takes just a few seconds for the smoke to start.<\/span><\/p>\n

Your eye is basically a very powerful magnifying glass, Van Gelder said. If you stare at the sun, you\u2019re focusing all the energy of that light onto your retina, the light-sensitive tissue in the back of your eye, and essentially burning a hole. You won’t feel it because the retina doesn\u2019t have any pain fibers, but the damage can happen after a few seconds.<\/span><\/p>\n

We all have a natural aversion to staring at very bright lights, but we also have the ability to overcome it.<\/span><\/p>\n

\u201cThe worry in the eclipse is that people are so interested to see one of the great astronomic spectacles that they will suppress their inner drive to look away from the very bright light,\u201d Van Gelder said.<\/span><\/p>\n

HOW YOUR VISION COULD BE AFFECTED<\/span><\/p>\n

The damage is known as solar retinopathy. That can include blind spots, distortions or loss of contrast in your central vision, which is what you use to read, drive and work on the computer.<\/span><\/p>\n

There have been reports of people becoming legally blind in at least one eye after watching eclipses, Van Gelder said.<\/span><\/p>\n

Studies show about one-quarter of patients who develop solar retinopathy suffer permanent damage, he added.<\/span><\/p>\n

SUNGLASSES WILL NOT PROTECT YOU<\/span><\/p>\n

Regular shades will \u201cabsolutely not\u201d defend your vision from the sun\u2019s powerful rays, Van Gelder warned. Even the darkest sunglasses do not reduce the amount of light hitting the back of your eyes by that much.<\/span><\/p>\n

\u201cThey\u2019re not an acceptable means for protecting your retina,\u201d if you stare directly at the sun, he said.<\/span><\/p>\n

WHAT TO LOOK FOR IN ECLIPSE VIEWING GLASSES<\/span><\/p>\n

These glasses have special-purpose solar filters, like Mylar, and wearing them may mean a million-fold decrease in the amount of light getting into the eye, Van Gelder said.<\/span><\/p>\n

\u201cThese glasses basically turn day to night,\u201d he noted.<\/span><\/p>\n

You must look for glasses that meet the ISO 12312-2 international standard for such products, NASA advises. You can buy the glasses online \u2014 the cardboard-frame versions cost just a few dollars \u2014 but check the American Astronomical Society’s list of reputable vendors first. You can also get glasses from your local library.<\/span><\/p>\n

Wear the glasses any time you want to look at the sun, even if there\u2019s only a small sliver of the star peeking behind the moon in a partial eclipse. That little sliver is still as bright and damaging as looking at direct sunlight, Van Gelder said.<\/span><\/p>\n

WHEN IT\u2019S OK TO LOOK AT THE ECLIPSE WITH THE NAKED EYE<\/span><\/p>\n

It\u2019s only safe if you are in the thin path of totality, which will pass through parts of 14 states, AND during the brief time when the moon fully eclipses the sun, when day turns into night, Van Gelder said.<\/span><\/p>\n

The instant the totality is over, immediately look away and put the special glasses back on. Don\u2019t walk or drive in them because you won\u2019t see much.<\/span><\/p>\n

\u201cMy strong, strong advice is take the two minutes to order the glasses for yourself and your family and then enjoy the eclipse without worrying that you\u2019re going to blind yourself by looking at it,\u201d Van Gelder said.<\/span><\/p>\n
