The Great American Eclipse Sun Valley Idaho August 21, 2017


On August 21, 2017, Ketchum and Sun Valley residents and visitors will experience a Total Solar Eclipse as the moon moves fully in front of the sun. This extraordinary moment marks the first total eclipse of the sun visible from all 48 contiguous United States since 1979 and the first visible from coast to coast in the US since 1918.

There will be several eclipses that pass over the US in the 21st century. This is only the first, but it has been a long time coming! If you miss this one, you will only need to wait seven years for another, it's true - but why wait?! And besides, the total eclipse in 2024 will also be visible from Mexico and Canada (in fact, Mexico is in many ways a better place to watch that one from!). So come on out for this one, and enjoy what will truly be considered "The Great American Eclipse!" 

People from all over the world begin to converge on the United States. Except for people returning home, visiting family, or conducting business at what happens to be just exactly the right time in history, these will be people who make it a point to travel to wherever the moon's shadow is going to touch the earth, and position themselves in a spot carefully chosen - sometimes years in advance - to ensure they see the sight. 

These people will make contingency travel plans in case of last-minute clouds. These people will fill hotel rooms, sometimes inadvertently displacing locals from their homes as space gets harder to come by. These people will travel through miles of desert or forest or frozen wasteland, braving the harshest of conditions...for a short glimpse at the eclipsed sun. 

These people are coming to America, because for the first time in 26 years, a total solar eclipse will occur in our great country, and we will play host to the world's eclipse-chasers. For those of us who already live here, but have never seen an eclipse, this is the opportunity of a lifetime - to see the most beautiful thing on the planet, and maybe not even have to get on an airplane to get to it!

August 21, 2017--Eclipse Day!

No human action can disrupt the incessant dance of the cosmos, and the moon's shadow will not wait on you if you're not ready. Like a mindless juggernaut, it plows its way through space toward a collision course with earth. As predicted by the astronomers decades in advance, the shadow arrives with perfect accuracy, and touches down in the north Pacific Ocean at 16:48:33 UT*, at local sunrise. (At that spot, the sun will actually rise while eclipsed. This is a sight few people - even veteran eclipse chasers - have seen, and from what we hear, it is quite uncanny.) 

A minute later, the entire shadow (the "umbral cone") will have made landfall - er, ocean-fall - and will be racing across the surface of the water at supersonic speed. Except for folks on ships at sea, and the occasional ocean-dwelling critter who dares to venture too near the surface, nothing sentient will note the passing of the umbra - until land gets in the way.


Armstrong-Root Welcomes World Renowned Ophthalmologist Dr. Bala Ambati 

In our continuing commitment to provide world class eye care to our patients we are most pleased to announce that beginning February 21, 2017 renowned ophthalmologist Dr. Balamurali Ambati will be seeing patients at our eye health clinic in Sun Valley/Ketchum, Idaho.

Dr. Ambati enjoys a reputation amongst his peers as one of the truly gifted eye surgeons in America. 

Having graduated Mount Sinai School of Medicine at seventeen and then ophthalmology residency at Harvard, Dr. Ambati is a true "Prodigy." His resume and biography are attached, please take the time to read them - We think you will be very impressed.

From 2008 to 2016, he worked at Moran Eye Institute at the University of Utah.

He recently moved to Eugene, Oregon, joining Pacific Clear Vision Institute & Surgical Center.

Consultations at Armstrong-Root begin on February 21, 2017 and will continue thereafter on a rotating six week basis. We anticipate that as his services are used that the frequency of his activities in Sun Valley will increase.

Armstrong-Root eyecare services are available daily. Examinations/refractions offered Mondays, Wednesdays, and Fridays. Please call for your appointment.


With summer around the corner, it's time for one of the indisputable laws of the universe to kick in: the more expensive your sunglasses are, the more likely you are to lose them. If you're prone to plunking your sunglasses in the lake and think it’s better to buy cheap ones instead, think again. Step away from the spinning rack at your local convenience store and take a second to consider the consequences.

The whole reason you're looking at $6.99 aviators in the first place is because it's bright outside. But those premature wrinkles from squinting all day under visible light isn't the biggest threat to your eyes; it's the invisible ultraviolet (UV) light that will hurt you, and you need sunglasses with built-in UV protection to safeguard your eyes. UV light is responsible for burning your winter-pale skin to a crisp, so you can imagine the effect such a burn might have on your un-sunscreen-able eyeballs. Plus, UV rays can damaga other parts of the eye and even contribute to cataracts and macular degeneration.

While super-dark shades might offer some protection against the obviously sunny day, if they are on a 2-for-1 deal alongside the beef sticks at the checkout line, they might not offer the 99 or 100 percent protection against UVA and UVB rays that eyecare professionals recommend.

Suppose you're at the Cadillac of gas stations, though, and those $12 Don Draper-style sunnies boast 100 percent UV protection. Jackpot! Not so fast, mad man. Another trait to look for in sunglasses is durability. Premium sunwear have impact resistance features that keep the lenses from breaking in a way that could endanger your eyes should a big impact occur.

Other considerations when it comes to purchasing sunglasses for your summer adventures is quality of optics — ask your golfing buddies to read a green when the middle of the lens has a wave like the North Shore of Oahu. And also consider the option of polarization. Never had polarized shades before? Get ready for a revelation, especially on the water. The lens technology blocks out a certain kind of reflected light that cuts glare and haze to make for a much more pleasant experience on the lake or the road (two spots where such reflected light waves are common).

On a lighter note, if you opt for mirrored sunglasses you always stand the chance of being mistaken for a big Hollywood star, or at least be able to watch a good-looking reveler walk by without getting a smack from your significant other.
