There is no total solar eclipse at the north pole or south pole
A total eclipse can happen anywhere on earth. The last solar eclipse from the north pole was March 2015.
The last south pole eclipse was November 2003.
Food prepared during an eclipse will be poisoned by the radiation
Food poisoning from solar eclipse radiation is clearly a false idea. Such radiation would almost certainly affect other food than that which was being prepared, including crops in the field that had not been harvested. This myth came from a period when solar eclipses were surely terrifying to those who neither understood nor could predict them. So if you happen to catch some food poisoning from the macaroni salad during the eclipse, it has less to do with the radiation than the preparation of your meal.
Pregnant mothers should not watch an eclipse to avoid harm to the baby
This fallacy is related to that of harmful radiation being emitted during a solar eclipse. While there is electromagnetic radiation from the corona at the point of total eclipse, it remains perfectly safe. It is also true, however, that every living second our bodies are exposed to forms of radiation from the solar system, having nothing whatsoever to do with an eclipse. Such an emission appears largely harmless and has no impact on pregnancy or a developing fetus.
The remarkable and dramatic cosmic event of an eclipse has happened throughout the history of mankind. During this historical span, our scientific understanding of the solar system has grown enormously. Consequently, older ideas about the cause and impact of a solar eclipse have been replaced by detailed scientific explanations. Even so, many early ideas are remarkably resistant to scientific explanation and understandings.
Harmful rays from the solar eclipse cause blindness
At the point of total solar eclipse, the moon fully covers the sun. The corona that is emitted at the time of total eclipse is only electromagnetic radiation, sometimes with a greenish aura. This radiation is a million times fainter than the light that emits from the sun itself. There is no light emission from the corona itself that could penetrate space, our dense atmosphere, and cause blindness. Importantly, if you watch the sun before the total eclipse, you can catch rays of the brilliant solar surface that are powerful enough to cause retinal damage. Thus it is safest to use special viewing techniques for the eclipse to avoid this critical timing.
A solar eclipse is a sign of an exceptional galactic event taking place somewhere in time and space
Solar eclipses can be predicted mathematically across thousands of years with great precision. Sir Isaac Newton observed over 300 years ago that there is a remarkable clockwork regularity to the universe, sometimes punctuated by unpredictable events. The eclipse that we observe is part of that clockwork regularity.
The eclipse causes the moon to turn completely black
Although it is difficult to see any light on the moon, careful observation with high-powered telescopes reveals more correctly that there is light on the moon during the eclipse. This faint light is a reflection of light from the earth back to the surface of the moon, referred to as earthshine. Because of the brilliance of the corona during the eclipse, the moon appears black.

What is the eclipse expected to show?
The bright face of the sun is covered gradually by the moon during a partial eclipse, lasting a few hours. During the brief period of a total eclipse when the moon fully covers the sun (only a couple of minutes), the light of day gives way to a deep twilight sky. The sun’s outer atmosphere (called the solar corona) gradually appears, glowing like a halo around the moon in front of it.
Bright stars and planets become more visible in the sky.
Watching a solar eclipse is a memorable experience, but looking directly at the sun can seriously damage your eyes. Staring at the sun for even a short time without wearing the right eye protection can damage your retina permanently. It can even cause blindness, called solar retinopathy.
There is only one safe way to look directly at the sun, whether during an eclipse or not: through special-purpose solar filters. These solar filters are used in “eclipse glasses” or in hand-held solar viewers.
They must meet a very specific worldwide standard known as ISO 12312-2.
Remember: ordinary sunglasses, even very dark ones, or
homemade filters are not safe for looking at the sun.
It is not better to sit up straight to read. Long term research in Finland has demonstrated a difference in ultimate degree of nearsightedness depending upon childrens’ preferred reading position up to age 20.
Mean nearsighted presciption at baseline was highest in those who sat to read, as was prescription progression for all follow-up visits.
Nearsightedness progression from baseline to their early 20s was lowest for those who reported reading lying on their backs, by a difference of 0.96 D and 1.38 D for men and women compared with progression in those who read in a seated position. Overall, there was about one-third less myopic progression in those reading on their backs compared with those whose reading posture was sitting.
Specialized prescription glasses have been found to be helpful in patients with migraine headaches, blepharospasm (eyelid spasms), light triggered seizures, CVS (Computer Vision Syndrome) and other light-sensitive/triggered conditions.
The wavelength filtered by FL-41 was first described in a research project that took place in Birmingham, England in the early 90’s. In this study, children with migraine headaches wore FL-41 filtered lenses. The researchers found that wearing the FL-41 filter improved the light sensitivity in these children, as well as lessened the frequency and severity of their migraine headaches. Since that time, FL-41 filtered lenses have been used to treat these and other conditions.
Blepharospasm and migraine patients suffer more from light sensitivity, vs. people who do not struggle with these conditions. Research at the University of Utah have also found that when these patients have had their light sensitivity treated, their blepharospasm and migraine symptoms have improved.
Recent research tested FL-41 filtered lenses, head-to-head, against conventional gray sunglasses and standard rose tinted spectacles. Notably, the majority of patients prefer wearing FL-41 filtered spectacles. Glasses with the specialized wavelength treatment are available at Northwest Vision Optical in Bellevue and Kirkland by prescription.
For those who find Omega-3 supplementation helpful to eye comfort and health it is attractive to take the least amount possible. The Krill oil manufacturers have sponsored research to try to convince that their tiny pills are the equivalent of fish oil omega 3. It appears they are.
However, what they never tell you is that the dose of omega-3 (EPA + DHA) in each capsule of Krill Oil is typically a small fraction of that found in a good fish oil capsule.
Our research has shown that the minimal dose of Omega-3 which will influence ocular comfort is 1200mg per day. This would be two to three of a medical grade, tryglyceride omega-3 supplement such as Nordic Naturals or 16 Mega Red capsules. At a cost per day, Krill Oil is not affordable for treatment.
One alternative to capsules is found in Barlean's Organic Ultra High Potency Omega Swirl now available at Northwest Vision. This is not an oil. It is a tasty fruit-flavored milkshake-like swirl which is technically an emulsion. This allows it to be digested more easily, in fewer steps than a fish oil without burps found in poorly manufactured fish oil such as those in the ester form. Advantage? Easier to digest, more omega-3 absorbed, and tasty too. One tablespoon delivers more than 3 of the fish oil capsules in our example.
Ultimately how much you need and what form is an individual decision guided by our exam of your exact eye condition and symptoms. We will also guide you on dose and omega-3 form.
Recent research confirms Dr. Gilbert’s long belief in the importance of relaxing music before and during eye surgery. A recent study shows relaxing music played just before eye surgery leads to patients feeling less anxiety and requiring less sedation.
Awake eye surgery can be stressful for some patients. Music has long been known to reduce anxiety, minimize sedative need, and allow patients to better relax.
Anxiety was significantly reduced among the music group (anxiety score 23 out of 100) compared to the non-music group (score 65 out of 100). The music group also needed significantly less sedatives during surgery compared with the non-music group (16% vs 32%). Postoperative satisfaction was significantly higher in the music group (mean score 71 out of 100 versus 55 for the non-music group). Music, well chosen, can relax the patient and surgical staff making surgery more pleasant, perhaps even fun, and ultimately safer for all.
